+<p>Blob provides the means to contain any opaque data. It is named after the term "Binary Large OBject" commonly used to describe unstructured data (such as encoded images) which is stored in a database. While the function of Blob is very simple (store a pointer and and size associated with allocated data), the Blob class provides some very useful capabilities. In particular, it is fully reference counted just like the Image class.</p>
+<p>The Blob class supports value assignment while preserving any outstanding earlier versions of the object. Since assignment is via a pointer internally, Blob is efficient enough to be stored directly in an STL container or any other data structure which requires assignment. In particular, by storing a Blob in an <a href="http://www.sgi.com/tech/stl/AssociativeContainer.html">associative container</a> (such as STL's '<a href="http://www.sgi.com/tech/stl/Map.html"><i>map</i></a>') it is possible to create simple indexed in-memory "database" of Blobs.</p>
+<p>Magick++ currently uses Blob to contain encoded images (e.g. JPEG) as well as ICC and IPTC profiles. Since Blob is a general-purpose class, it may be used for other purposes as well.</p>

+<h1 align="center">Magick::Color</h1>
+<p><a href="#Color">Color</a> is the base color class in Magick++. It is a simple container class for the pixel red, green, blue, and alpha values scaled to fit ImageMagick's Quantum size. Normally users will instantiate a class derived from Color which supports the color model that fits the needs of the application. The Color class may be constructed directly from an SVG-style color string.</p>
+<h4>Quantum</h4>
+
+The base type used to represent color samples in ImageMagick is the Quantum type. Pixels are represented by a structure of Quantum values. For example, an RGB pixel contains red, green, and blue quantums, while an RGBA pixel contains red, green, blue, and opacity quantums. The maximum value that a Quantum can attain is specified by a constant value represented by the MaxRGB define, which is itself determined by the number of bits in a Quantum. The QuantumDepth build option determines the number of bits in a Quantum.
+
+<h4>Quantum</h4>
+
+Quantum is the internal representation of a pixel in ImageMagick. ImageMagick may be compiled to support 32, 64, or 128 bit pixels of type Quantum. This is controlled by the value of the QuantumDepth define. The default is 32 bit pixels (QuantumDepth=8), which provides the best performance and the least resource consumption. If additional color precision or range is desired, then ImageMagick may be compiled with QuantumDepth=16 or QuantumDepth=32. The following table shows the relationship between QuantumDepth, the type of Quantum, and the overall Quantum size.

+<h3><a name="Color"></a>Color Class</h3>
+<p>The Color base class is not intended to be used directly. Normally a user will construct a derived class or inherit from this class. Color arguments are must be scaled to fit the Quantum size. The Color class contains a pointer to a Quantum, which may be allocated by the Color class, or may refer to an existing pixel in an image.</p>
+<p>An alternate way to construct the class is via an SVG-compatible color specification string (e.g. Color("red") or Color ("#FF0000")). Since the class may be constructed from a string, convenient strings may be passed in place of an explicit Color object in methods which accept a reference to Color. Color may also be converted to a std::string for convenience in user interfaces, and for saving settings to a text file.</p>

+<p>Drawable provides a convenient interface for preparing vector, image, or text arguments for the Image::draw() method. Each instance of a Drawable sub-class represents a single drawable object. Drawable objects may be drawn "one-by-one" via multiple invocations of the Image <a href="Image++.html#draw">draw</a>() method, or may be drawn "all-at-once" by passing a list of Drawable objects to the Image <a href="Image++.html#draw">draw</a>() method. The one-by-one approach is convenient for simple drawings, while the list-based approach is appropriate for drawings which require more sophistication.</p>
+<p>The following is an example using the Drawable subclasses with a one-by-one approach to draw the following figure:</p>
+<p class="image"><font color="#000000"><font color="#000000"><img
+ src="Drawable_example_1.png" name="Graphic1" align="bottom" border="3"
+ height="200" width="300" alt="example" /></font></font>
+</p>
+<div class="viewport">
+#include <string>
+#include <iostream>
+#include <Magick++.h>
+
+using namespace std;
+using namespace Magick;
+
+int main(int /*argc*/,char **argv)
+{
+ try {
+ InitializeMagick(*argv);
+
+ // Create base image (white image of 300 by 200 pixels)
+ Image image( Geometry(300,200), Color("white") );
+
+ // Set draw options
+ image.strokeColor("red"); // Outline color
+ image.fillColor("green"); // Fill color
+ image.strokeWidth(5);
+
+ // Draw a circle
+ image.draw( DrawableCircle(100,100, 50,100) );
+
+ // Draw a rectangle
+ image.draw( DrawableRectangle(200,200, 270,170) );
+
+ // Display the result
+ image.display( );
+ }
+ catch( exception & error_ )
+ {
+ cout << "Caught exception: " << error_.what() << endl;
+ return 1;
+ }
+
+ return 0;
+}
+</div>
+<p>Since Drawable is an object it may be saved in an array or a list for later (perhaps repeated) use. The following example shows how to draw the same figure using the list-based approach:</p>

+
+ // Create base image (white image of 300 by 200 pixels)
+ Image image( Geometry(300,200), Color("white") );
+
+ // Construct drawing list
+ std::list<Magick::Drawable> drawList;
+
+ // Add some drawing options to drawing list
+ drawList.push_back(DrawableStrokeColor("red")); // Outline color

+<h2 style="text-align:center">Vector Path Classes</h2>
+<p>The vector paths supported by Magick++ are based on those supported by the <a href="http://www.w3.org/TR/SVG/paths.html">SVG XML specification</a>. Vector paths are not directly drawable, they must first be supplied as a constructor argument to the <a href="#DrawablePath">DrawablePath</a> class in order to create a drawable object. The <a href="#DrawablePath">DrawablePath</a> class effectively creates a drawable compound component which may be replayed as desired. If the drawable compound component consists only of vector path objects using relative coordinates then the object may be positioned on the image by preceding it with a <i>DrawablePath</i> which sets the current drawing coordinate. Alternatively coordinate transforms may be used to <a href="#DrawableTranslation">translate the origin</a> in order to position the object, <a href="#DrawableRotation">rotate</a> it, <a href="#DrawableSkewX">skew</a> it, or <a href="#DrawableScaling">scale</a> it.</p>

A path data segment must begin with either one of the "moveto" commands or one of the "arc" commands.

+<p>The ColorspaceType enumeration is used to specify the colorspace
+that quantization (color reduction and mapping) is done under or to
+specify the colorspace when encoding an output image. Colorspaces are
+ways of describing colors to fit the requirements of a particular
+application (e.g. Television, offset printing, color monitors).
+Color reduction, by default, takes place in the <i>RGBColorspace</i>.
+Empirical evidence suggests that distances in color spaces such as
+<i>YUVColorspace</i> or <i>YIQColorspace</i> correspond to perceptual
+color differences more closely han do distances in RGB space. These
+color spaces may give better results when color reducing an image.
+Refer to <i>quantize</i> for more details.

+Photoshop bitmap (PSD) files.

+<div class="doc-section">
+<h1 align="center">Magick::Exception Classes</h1>
+<p><i>Exception</i> represents the base class of objects thrown when
+Magick++reports an error. Magick++ throws C++ exceptions synchronous
+with the operation where the error occurred. This allows errors to be
+trapped within the enclosing code (perhaps the code to process a
+single image) while allowing the code to be written with a simple
+coding style.</p>
+<p>A try/catch block should be placed around any sequence of
+operations which can be considered an important body of work. For
+example, if your program processes lists of images and some of these
+images may be defective, by placing the try/catch block around the
+entire sequence of code that processes one image (including
+instantiating the image object), you can minimize the overhead of
+error checking while ensuring that all objects created to deal with
+that object are safely destroyed (C++ exceptions unroll the stack
+until the enclosing try block, destroying any created objects).
+</p>
+<p>The pseudo code for the main loop of your program may look like:
+</p>
+<div class="viewport">
+using namespace std;
+for infile in list
+{
+ try {
+ // Construct an image instance first so that we don't have to worry
+ // about object construction failure due to a minor warning exception
+ // being thrown.
+ Magick::Image image;
+ try {
+ // Try reading image file
+ image.read(infile);
+ }
+ catch( Magick::WarningCoder &warning )
+ {
+ // Process coder warning while loading file (e.g. TIFF warning)
+ // Maybe the user will be interested in these warnings (or not).
+ // If a warning is produced while loading an image, the image
+ // can normally still be used (but not if the warning was about
+ // something important!)
+ cerr << "Coder Warning: " << warning.what() << endl;
+ }
+ catch( Magick::Warning &warning )
+ {
+ // Handle any other Magick++ warning.
+ cerr << "Warning: " << warning.what() << endl;
+ }
+ catch( Magick::ErrorFileOpen &error )
+ {
+ // Process Magick++ file open error
+ cerr << "Error: " << error.what() << endl;
+ continue; // Try next image.
+ }
+ try {
+ image.rotate(90);
+ image.write("outfile");
+ }
+ catch ( MagickExeption & error)
+ {
+ // Handle problem while rotating or writing outfile.
+ cerr << "Caught Magick++ exception: " << error.what() << endl;
+ }
+ }
+ catch( std::exception & error )
+ {
+ // Process any other exceptions derived from standard C++ exception
+ cerr << "Caught C++ STD exception: " << error.what() << endl;
+ }
+ catch( ... )
+ {
+ // Process *any* exception (last-ditch effort). There is not a lot
+ // you can do here other to retry the operation that failed, or exit
+ }
+}
+</div>
+<p>The desired location and number of try/catch blocks in your program
+depends how sophisticated its error handling must be. Very simple
+programs may use just one try/catch block.</p>
+<p>The <i>Exception</i> class is derived from the C++ standard
+exception class. This means that it contains a C++ string containing
+additional information about the error (e.g to display to the user).
+Obtain access to this string via the what() method.  For
+example:
+</p>
+<pre class="code">
+catch( Exception & error_ )
+ {
+ cout << "Caught exception: " << error_.what() << endl;
+ }
+</pre>
+<p>The classes <i>Warning</i> and <i>Error</i> derive from the
+<i>Exception</i> class. Exceptions derived from <i>Warning</i> are
+thrown to represent non-fatal errors which may effect the
+completeness or quality of the result (e.g. one image provided as an
+argument to montage is defective). In most cases, a <i>Warning</i>
+exception may be ignored by catching it immediately, processing it
+(e.g. printing a diagnostic) and continuing on. Exceptions derived
+from <i>Error</i> are thrown to represent fatal errors that can not
+produce a valid result (e.g. attempting to read a file which does not
+exist).

+offsets are measured from the indicated edge of the object to the

+<h3><a name="PostscriptPageSize"></a>Postscript Page Size Extension
+To Geometry Specifications</h3>
+<p>Any geometry string specification supplied to the Geometry
+constructor is considered to be a Postscript page size nickname if
+the first character is not numeric. The Geometry constructor converts
+these page size specifications into the equivalent numeric geometry
+string specification (preserving any offset component) prior to
+conversion to the internal object format. Postscript page size
+specifications are short-hand for the pixel geometry required to fill
+a page of that size. Since the 11x17 inch page size used in the US
+starts with a digit, it is not supported as a Postscript page size
+nickname. Instead, substitute the geometry specification "<kbd>792x1224>"</kbd>
+when 11x17 output is desired.
+</p>
+<p style="margin-bottom: 0in">An example of a Postscript page size
+specification is <kbd>"letter+43+43>"</kbd>.

+<p>Image is the primary object in Magick++ and represents
+a single image frame (see <a href="http://www.imagemagick.org/Magick++/ImageDesign.html">design</a> ). The
+<a href="http://www.imagemagick.org/Magick++/STL.html">STL interface</a> <b>must</b> be used to operate on
+image sequences or images (e.g. of format GIF, TIFF, MIFF, Postscript,
+& MNG) which are comprized of multiple image frames. Individual
+frames of a multi-frame image may be requested by adding array-style
+notation to the end of the file name (e.g. "animation.gif[3]" retrieves
+the fourth frame of a GIF animation.  Various image manipulation
+operations may be applied to the image. Attributes may be set on the
+image to influence the operation of the manipulation operations. The <a
+ href="http://www.imagemagick.org/Magick++/Pixels.html"> Pixels</a> class provides low-level access to
+image
+pixels. As a convenience, including <tt><font color="#663366"><Magick++.h></font></tt>
+is sufficient in order to use the complete Magick++ API. The Magick++
+API is enclosed within the <i>Magick</i> namespace so you must either
+add the prefix "<tt> Magick::</tt> " to each class/enumeration name or
+add
+the statement "<tt> using namespace Magick;</tt>" after including the <tt>Magick++.h</tt>
+header.</p>
+<p>The preferred way to allocate Image objects is via automatic
+allocation (on the stack). There is no concern that allocating Image
+objects on the stack will excessively enlarge the stack since Magick++
+allocates all large data objects (such as the actual image data) from
+the heap. Use of automatic allocation is preferred over explicit
+allocation (via <i>new</i>) since it is much less error prone and
+allows use of C++ scoping rules to avoid memory leaks. Use of automatic
+allocation allows Magick++ objects to be assigned and copied just like
+the C++ intrinsic data types (e.g. '<i>int</i> '), leading to clear and
+easy to read code. Use of automatic allocation leads to naturally
+exception-safe code since if an exception is thrown, the object is
+automagically deallocated once the stack unwinds past the scope of the
+allocation (not the case for objects allocated via <i>new</i> ). </p>
+<p>Image is very easy to use. For example, here is a the source to a
+program which reads an image, crops it, and writes it to a new file
+(the
+exception handling is optional but strongly recommended): </p>
+<pre class="code">
+#include <Magick++.h>
+#include <iostream>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ InitializeMagick(*argv);
+
+ // Construct the image object. Seperating image construction from the
+ // the read operation ensures that a failure to read the image file
+ // doesn't render the image object useless.
+ Image image;
+ try {
+ // Read a file into image object
+ image.read( "girl.gif" );
+
+ // Crop the image to specified size (width, height, xOffset, yOffset)
+ image.crop( Geometry(100,100, 100, 100) );
+
+ // Write the image to a file
+ image.write( "x.gif" );
+ }
+ catch( Exception &error_ )
+ {
+ cout << "Caught exception: " << error_.what() << endl;
+ return 1;
+ }
+ return 0;
+}
+</pre>
+The following is the source to a program which illustrates the use of
+Magick++'s efficient reference-counted assignment and copy-constructor
+operations which minimize use of memory and eliminate unncessary copy
+operations (allowing Image objects to be efficiently assigned, and
+copied into containers).  The program accomplishes the
+following:
+<ol>
+ <li> Read master image.</li>
+ <li> Assign master image to second image.</li>
+ <li> Resize second image to the size 640x480.</li>
+ <li> Assign master image to a third image.</li>
+ <li> Resize third image to the size 800x600.</li>
+ <li> Write the second image to a file.</li>
+ <li> Write the third image to a file.</li>
+</ol>
+<pre class="code">
+#include <Magick++.h>
+#include <iostream>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ InitializeMagick(*argv);
+
+ Image master("horse.jpg");
+ Image second = master;
+ second.resize("640x480");
+ Image third = master;
+ third.resize("800x600");
+ second.write("horse640x480.jpg");
+ third.write("horse800x600.jpg");
+ return 0;
+}
+</pre>
+During the entire operation, a maximum of three images exist in memory
+and the image data is never copied.
+<p>The following is the source for another simple program which creates
+a 100 by 100 pixel white image with a red pixel in the center and
+writes it to a file: </p>
+<pre class="code">
+#include <Magick++.h>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ InitializeMagick(*argv);
+ Image image( "100x100", "white" );
+ image.pixelColor( 49, 49, "red" );
+ image.write( "red_pixel.png" );
+ return 0;
+}
+</pre>
+If you wanted to change the color image to grayscale, you could add the
+lines:
+<pre class="code">
+image.quantizeColorSpace( GRAYColorspace );
+image.quantizeColors( 256 );
+image.quantize( );
+</pre>
+<p>or, more simply: </p>
+<pre class="code">
+ image.type( GrayscaleType );
+</pre>
+<p>prior to writing the image. </p>
+<center>
+<h3> <a name="BLOBs"></a> BLOBs</h3>
+</center>
+While encoded images (e.g. JPEG) are most often written-to and
+read-from a disk file, encoded images may also reside in memory.
+Encoded
+images in memory are known as BLOBs (Binary Large OBjects) and may be
+represented using the <a href="http://www.imagemagick.org/Magick++/Blob.html">Blob</a> class. The encoded
+image may be initially placed in memory by reading it directly from a
+file, reading the image from a database, memory-mapped from a disk
+file, or could be written to memory by Magick++. Once the encoded image
+has been placed within a Blob, it may be read into a Magick++ Image via
+a <a href="Image++.html#constructor_blob">constructor</a> or <a href="Image++.html#read">read()</a>
+. Likewise, a Magick++ image may be written to a Blob via <a
+ href="Image++.html#write"> write()</a> .
+<p>An example of using Image to write to a Blob follows: <br />
+  </p>
+<pre class="code">
+#include >Magick++.h>
+using namespace std;
+using namespace Magick;
+int main(int argc,char **argv)
+{
+ InitializeMagick(*argv);
+
+ // Read GIF file from disk
+ Image image( "giraffe.gif" );
+ // Write to BLOB in JPEG format
+ Blob blob;
+ image.magick( "JPEG" ) // Set JPEG output format
+ image.write( &blob );
+
+ [ Use BLOB data (in JPEG format) here ]
+
+ return 0;
+}
+</pre>
+<p><br />
+likewise, to read an image from a Blob, you could use one of the
+following examples: </p>
+<p>[ <font color="#000000">Entry condition for the following examples
+is that <i>data</i> is pointer to encoded image data and <i>length</i>
+represents the size of the data</font> ] </p>
+<pre class="code">
+Blob blob( data, length );
+Image image( blob );
+</pre>
+or
+<pre class="code">
+Blob blob( data, length );
+Image image;
+image.read( blob);
+</pre>
+some images do not contain their size or format so the size and format must be specified in advance:
+<pre class="code">
+Blob blob( data, length );
+Image image;
+image.size( "640x480")
+image.magick( "RGBA" );
+image.read( blob);
+</pre>

+Methods</h3>

+<i>Image</i> supports access to all the single-image (versus
+image-list) manipulation operations provided by the ImageMagick
+library. If you
+must process a multi-image file (such as an animation), the <a
+ href="http://www.imagemagick.org/Magick++/STL.html"> STL interface</a> , which provides a multi-image
+abstraction on top of <i>Image</i>, must be used.
+<p>Image manipulation methods are very easy to use.  For example: </p>
+<pre class="code">
+Image image;
+image.read("myImage.tiff");
+image.addNoise(GaussianNoise);
+image.write("myImage.tiff");
+</pre>
+adds gaussian noise to the image file "myImage.tiff".
+<p>The operations supported by Image are shown in the following table: <br />

+<h3> <a name="Image Attributes"></a> Image Attributes</h3>

+Image attributes are set and obtained via methods in Image. Except for
+methods which accept pointer arguments (e.g. c<tt>hromaBluePrimary)</tt>
+all methods return attributes by value.
+<p>Image attributes are easily used. For example, to set the resolution
+of the TIFF file "file.tiff" to 150 dots-per-inch (DPI) in both the
+horizontal and vertical directions, you can use the following example
+code: </p>
+<pre class="code">
+string filename("file.tiff");
+Image image;
+image.read(filename);
+image.resolutionUnits(PixelsPerInchResolution);
+image.density(Geometry(150,150)); // could also use image.density("150x150")
+image.write(filename)
+</pre>
+The supported image attributes and the method arguments required to
+obtain them are shown in the following table: <br />

+<h3> <a name="Raw Image Pixel Access"></a> Low-Level Image Pixel Access</h3>
+</center>
+Image pixels (of type <i><a href="http://www.imagemagick.org/Magick++/Quantum.html">Quantum</a> </i>)
+may be accessed directly via the <i>Image Pixel Cache</i> .  The
+image pixel cache is a rectangular window into the actual image pixels
+(which may be in memory, memory-mapped from a disk file, or entirely on
+disk). Two interfaces exist to access the <i>Image Pixel Cache.</i>
+The
+interface described here (part of the <i>Image</i> class) supports
+only
+one view at a time. See the <i><a href="http://www.imagemagick.org/Magick++/Pixels.html">Pixels</a> </i>
+class for a more abstract interface which supports simultaneous pixel
+views (up to the number of rows). As an analogy, the interface
+described
+here relates to the <i><a href="http://www.imagemagick.org/Magick++/Pixels.html">Pixels</a> </i> class as
+stdio's gets() relates to fgets(). The <i><a href="http://www.imagemagick.org/Magick++/Pixels.html"> Pixels</a>
+</i>class provides the more general form of the interface.
+<p>Obtain existing image pixels via <i>getPixels()</i>. Create a new
+pixel region using <i>setPixels().</i></p>
+<p>In order to ensure that only the current generation of the image is
+modified, the Image's <a href="Image++.html#modifyImage">modifyImage()</a> method
+should be invoked to reduce the reference count on the underlying image
+to one. If this is not done, then it is possible for a previous
+generation of the image to be modified due to the use of reference
+counting when copying or constructing an Image.<br />
+</p>
+<p>Depending on the capabilities of the operating system, and the
+relationship of the window to the image, the pixel cache may be a copy
+of the pixels in the selected window, or it may be the actual image
+pixels. In any case calling <i>syncPixels()</i> insures that the base
+image is updated with the contents of the modified pixel cache. The
+method <i> readPixels()</i> supports copying foreign pixel data
+formats
+into the pixel cache according to the <i>QuantumTypes</i>. The method <i>writePixels()</i>
+supports copying the pixels in the cache to a foreign pixel
+representation according to the format specified by <i>QuantumTypes</i>.</p>
+<p>The pixel region is effectively a small image in which the pixels
+may be accessed, addressed, and updated, as shown in the following
+example:</p>
+<pre class="code">
+<img class="icon" src="http://www.imagemagick.org/Magick++/Cache.png" name="Graphic1" width="254" border="0" alt="cache" />
+Image image("cow.png");
+// Ensure that there are no other references to this image.
+image.modifyImage();
+// Set the image type to TrueColor DirectClass representation.
+image.type(TrueColorType);
+// Request pixel region with size 60x40, and top origin at 20x30
+ssize_t columns = 60;
+Quantum *pixel_cache = image.getPixels(20,30,columns,40);
+// Set pixel at column 5, and row 10 in the pixel cache to red.
+ssize_t column = 5;
+ssize_t row = 10;
+Quantum *pixel = pixel_cache+row*columns+column;
+*pixel = Color("red");
+// Save changes to underlying image .
+image.syncPixels();
+ // Save updated image to file.
+image.write("horse.png");
+</pre>

+<h1>Magick::Image Data Structures</h1></center>
+The class Magick::Image is a simple handle which points to a reference-counted image representation. This allows multiple Magick::Image instances to share the same image and attributes. At the point in time that the image data, or image attributes are modified and the current reference count is greater than one, the image data and attributes are copied to create a new image with a reference count of one and the reference count on the old image is decremented. If the reference count on the old image becomes zero, then the associated reference and data are deleted. This strategy represents a simple (but effective) form of garbage collection

+<h1 align="center">Installing Magick++</h1>
+<h3>General</h3>
+<p>In order to compile Magick++ you must have access to a standard C++ implementation. The author uses <a href="http://gcc.gnu.org/index.html">gcc 3.4 (GNU C++)</a> which is available under UNIX and under the <a href="http://www.cygwin.com/">Cygwin UNIX-emulation environment</a> for Windows. Standards compliant commercial C++ compilers should also work fine. Most modern C++ compilers for Microsoft Windows or the Mac should work (project files are provided for Microsoft Visual C++ 8.0).</p>
+<p>It was decided that Magick++ will be around for the long-haul, so its API definition depends on valuable C++ features which should be common in all current and future C++ compilers. The compiler must support the following C++ standard features:</p>
+<ul>
+<li>
+<p style="margin-bottom: 0cm">templates</p></li>
+<li>
+<p style="margin-bottom: 0cm">static constructors</p></li>
+<li>
+<p style="margin-bottom: 0cm">C++-style casts (e.g. static_cast)</p></li>
+<li>
+<p style="margin-bottom: 0cm">bool type</p></li>
+<li>
+<p style="margin-bottom: 0cm">string class (<tt><string></tt>)</p></li>
+<li>
+<p style="margin-bottom: 0cm">exceptions (<tt><exception></tt>)</p></li>
+<li>
+<p style="margin-bottom: 0cm">namespaces</p></li>
+<li>
+<p>Standard Template Library (STL) (e.g. <tt><list></tt>, <tt><vector></tt>)</p></li></ul>
+<p style="margin-bottom: 0cm">The author has personally verified that Magick++ compiles and runs using the following compiler/platform combinations:</p>

+<h4>Building From Source</h4>
+<p>Magick++ is now built using the ImageMagick configure script and Makefiles. Please follow the installation instructions provided by its README.txt file. The following instructions pertain to the Magick++ specific configuration and build options.</p>
+<p>To install ImageMagick plus Magick++ under Unix, installation should be similar to</p>
+<p><tt>./configure [ --prefix=/prefix ]</tt><br />
+<tt>make</tt><br />
+<tt>make install</tt></p>
+<p>The library is currently named similar to 'libMagick++.a' (and/or libMagick++.so.5.0.39) and is installed under prefix/lib while the headers are installed with Magick++.h being installed in prefix/include and the remaining headers in prefix/include/Magick++.</p>
+<p>To influence the options the configure script chooses, you may specify 'make' option variables when running the configure script. For example, the command</p>
+<blockquote><tt>./configure CXX=CC CXXFLAGS=-O2 LIBS=-lposix</tt></blockquote>
+<p style="margin-bottom: 0cm"><br />
+specifies additional options to the configure script. The following table shows the available options.</p>

+<h3 align="center">Windows '9X, NT, 2003, 2008, XP, & Windows 7</h3>
+<h4>Visual C++</h4>
+<p>Windows NT through Windows Vista are supported by the ImageMagick source package for NT available in the 'win2k' subdirectory of the ImageMagick ftp site (and mirrors). The ImageMagick source package for NT provides sources to ImageMagick, Magick++, add-on libraries (e.g. JPEG), and a ready-made Visual C++ 8.0 build environment. Please read the configuration and build instructions in README.txt (under the heading "Windows Win2K/XP VISUAL C++ 8.0 COMPILATION") in order to build Magick++.</p>
+<h4>Cygwin & GCC</h4>
+<p>It is possible to build both ImageMagick and Magick++ under the Cygwin Unix-emulation environment for Windows NT. Obtain and install Cgywin from <a href="http://www.cygwin.com/">http://www.cygwin.com/</a> . An X11R6 environment for Cygwin is available from <a href="http://www.cygwin.com/xfree/">http://www.cygwin.com/xfree/</a> .To build using Cygwin and GCC, follow the instructions for building under Unix.</p>

+<p>A montage is a single image which is composed of thumbnail images composed in a uniform grid. The size of the montage image is determined by the size of the individual thumbnails and the number of rows and columns in the grid.</p>
+<p>The following illustration shows a montage consisting of three columns and two rows of thumbnails rendered on a gray background:</p>
+<p class="image"><img src="montage-sample-framed.jpg" name="Graphic1" align="bottom" width="378" height="238" border="0"/></p>
+<p>Montages may be either "plain" (undecorated thumbnails) or "framed" (decorated thumbnails). In order to more easily understand the options supplied to <a href="STL.html#montageImages"><i>MontageImages()</i></a>, montage options are supplied by two different classes: <a href="#Magick::Montage"><i>Magick::Montage</i></a> and <a href="#Magick::MontageFramed"><i>Magick::MontageFramed</i></a>.</p>

+<p>The <i>Pixels</i> class provides efficient access to raw image
+pixels. Image pixels (of type <a href="Quantum.html"><i>Quantum</i></a>)
+may be accessed directly via the <i>Image Pixel Cache</i>. The image
+pixel cache is a rectangular window (a view) into the actual image
+pixels (which may be in memory, memory-mapped from a disk file, or
+entirely on disk). Obtain existing image pixels via <i>get()</i>.
+Create a new pixel region using <i>set().</i> </p>
+<p>Depending on the capabilities of the operating system, and the
+relationship of the window to the image, the pixel cache may be a copy
+of the pixels in the selected window, or it may be the actual image
+pixels. In any case calling <i>sync()</i> insures that the base image
+is updated with the contents of the modified pixel cache. The method <i>decode()</i>supports
+copying foreign pixel data formats into the pixel cache according to
+the <i>QuantumTypes</i>. The method <i>encode()</i> supports copying
+the pixels in the cache to a foreign pixel representation according to
+the format specified by <i>QuantumTypes</i>. </p>
+<p>Setting a view using the Pixels class does not cause the number of
+references to the underlying image to be reduced to one. Therefore, in
+order to ensure that only the current generation of the image is
+modified, the Image's <a href="Image++.html#modifyImage">modifyImage()</a>
+method should be invoked to reduce the reference count on the underlying
+image to one. If this is not done, then it is possible for a previous
+generation of the image to be modified due to the use of reference
+counting when copying or constructing an Image. </p>
+<p>The <i>Quantum</i>* returned by the <i>set</i> and <i>get</i>
+methods, and the <i>void</i>* returned by the <i>indexes</i>
+method point to pixel data managed by the <i>Pixels</i> class. The <i>Pixels</i>
+class is responsible for releasing resources associated with the pixel
+view. This means that the pointer should never be passed to delete() or
+free(). </p>
+<p style="margin-bottom: 0cm;">The pixel view is a small image in which
+the pixels may be accessed, addressed, and updated, as shown in the
+following example, which produces an image similar to the one on the
+right (minus lines and text): </p>

+<h1> Magick++ STL Support</h1>
+Magick++ provides a set of <a href="http://www.sgi.com/tech/stl/">Standard
+Template Libary</a> (<a href="http://www.sgi.com/tech/stl/">STL</a> )
+algorithms for operating across ranges of image frames in a container.
+It also provides a set of STL unary function objects to apply an
+operation on image frames in a container via an algorithm which uses
+unary function objects. A good example of a standard algorithm which is
+useful for processing containers of image frames is the STL <i><a
+ href="http://www.sgi.com/tech/stl/for_each.html"> for_each</a> </i>
+algorithm which invokes a unary function object on a range of container
+elements.
+<p>Magick++ uses a limited set of template argument types. The current
+template argument types are: </p>
+<a href="http://www.sgi.com/tech/stl/Container.html">Container</a>
+<blockquote>A container having the properties of a <a
+ href="http://www.sgi.com/tech/stl/BackInsertionSequence.html"> Back
+Insertion Sequence</a> . Sequences support forward iterators and Back
+Insertion Sequences support the additional abilty to append an element
+via push_back(). Common compatable container types are the STL <<a
+ href="http://www.sgi.com/tech/stl/Vector.html"> vector</a> > and <<a
+ href="http://www.sgi.com/tech/stl/List.html">list</a> > template
+containers. This template argument is usually used to represent an
+output container in which one or more image frames may be appended.
+Containers like STL <<a href="http://www.sgi.com/tech/stl/Vector.html">vector</a>
+> which have a given default <i>capacity</i> may need to have their <i>
+capacity</i> adjusted via r<i>eserve() </i>to a larger <i>capacity</i>
+in order to support the expected final <i>size</i> . Since Magick++
+images are very small, it is likely that the default capacity of STL <<a
+ href="http://www.sgi.com/tech/stl/Vector.html"> vector</a> > is
+sufficient for most situations.</blockquote>
+ <a href="http://www.sgi.com/tech/stl/InputIterator.html">InputIterator</a>
+ <blockquote>An input iterator used to express a position in a
+container. These template arguments are typically used to represent a
+range of elements with f<i>irst_</i> representing the first element to
+be processed and <i> last_</i> representing the element to stop at. When
+processing the entire contents of a container, it is handy to know that
+STL containers usually provide the begin() and end() methods to return
+input interators which correspond with the first and last elements,
+respectively.</blockquote>
+<p>The following is an example of how frames from a GIF animation <font
+ color="#000000"> "test_image_anim.gif" may be appended horizontally
+with the resulting image written to the file <kbd>appended_image.miff</kbd>:</font></p>
+<pre class="code">
+#include <list>
+#include <Magick++.h>
+using namespace std;
+using namespace Magick;
+
+int main(int /*argc*/,char **/*argv*/)
+{
+ list<Image> imageList;
+ readImages( &imageList, "test_image_anim.gif" );
+
+ Image appended;
+ appendImages( &appended, imageList.begin(), imageList.end() );
+ appended.write( "appended_image.miff" );
+ return 0;
+}
+</pre>

+sequences of image frames are shown in the following table: <br />

+<h3> Magick++ Unary Function Objects</h3>
+</center>
+Magick++ unary function objects inherit from the STL unary_function
+template class . The STL unary_function template class is of the form
+<pre class="text"><tt><font color="#000099">unary_function<Arg, Result></font></tt></pre>
+and expects that derived classes implement a method of the form:
+<pre class="text"><tt><font color="#000099">Result operator()( Arg argument_);</font></tt></pre>
+which is invoked by algorithms using the function object. In the case
+of unary function objects defined by Magick++, the invoked function
+looks like:
+<pre class="text"><tt><font color="#000099">void operator()( Image &image_);</font></tt></pre>
+with a typical implementation looking similar to:

+where <i>contrast</i> is an Image method and <i>_sharpen </i>is an
+argument stored within the function object by its contructor. Since
+constructors may be polymorphic, a given function object may have
+several constructors and selects the appropriate Image method based on
+the arguments supplied.
+<p>In essence, unary function objects (as provided by Magick++) simply
+provide the means to construct an object which caches arguments for
+later use by an algorithm designed for use with unary function objects.
+There is a unary function object corresponding each algorithm provided
+by the <a href="https://www.imagemagick.org/Magick++/Image++.html"> Image</a> class and there is a contructor
+available compatable with each synonymous method in the Image class. </p>
+<p>The unary function objects that Magick++ provides to support
+manipulating images are shown in the following table: <br />

+<h3> Query Image Format Support</h3>
+</center>
+<p>Magick++ provides the <a name="coderInfoList"></a> <i>coderInfoList()</i>
+function to support obtaining information about the image formats
+supported by ImageMagick. Support for image formats in ImageMagick
+is provided by modules known as "coders". A user-provided container is
+updated based on a boolean truth-table match. The truth-table supports
+matching based on whether ImageMagick can read the format, write the
+format, or supports multiple frames for the format. A wildcard specifier
+is supported for any "don't care" field. The data obtained via
+coderInfoList() may be useful for preparing GUI dialog boxes or for
+deciding which output format to write based on support within the
+ImageMagick build.</p>
+<p>The definition of coderInfoList is: </p>
+<pre class="code">
+class CoderInfo
+ {
+ public:
+
+ enum MatchType {
+ AnyMatch, // match any coder
+ TrueMatch, // match coder if true
+ FalseMatch // match coder if false
+ };
+
+ [ remaining CoderInfo methods ]
+
+ }
+
+ template <class Container >
+ void coderInfoList( Container *container_,
+ CoderInfo::MatchType isReadable_ = CoderInfo::AnyMatch,
+ CoderInfo::MatchType isWritable_ = CoderInfo::AnyMatch,
+ CoderInfo::MatchType isMultiFrame_ = CoderInfo::AnyMatch
+ );
+</pre>
+<p>The following example shows how to retrieve a list of all of the
+coders which support reading images and print the coder attributes (all
+listed formats will be readable): </p>
+<pre class="code">
+ list<CoderInfo> coderList;
+ coderInfoList( &coderList, // Reference to output list
+ CoderInfo::TrueMatch, // Match readable formats
+ CoderInfo::AnyMatch, // Don't care about writable formats
+ CoderInfo::AnyMatch); // Don't care about multi-frame support
+ list<CoderInfo>::iterator entry = coderList.begin();
+ while( entry != coderList.end() )
+ {
+ cout << entry->name() << ": (" << entry->description() << ") : ";
+ cout << "Readable = ";
+ if ( entry->isReadable() )
+ cout << "true";
+ else
+ cout << "false";
+ cout << ", ";
+ cout << "Writable = ";
+ if ( entry->isWritable() )
+ cout << "true";
+ else
+ cout << "false";
+ cout << ", ";
+ cout << "Multiframe = ";

+<h3 style="text-align: center;">Obtaining A Color Histogram  </h3>
+<p>Magick++ provides the <a name="colorHistogram"></a><span
+ style="font-weight: bold;">colorHistogram</span> template function to
+retrieve a color histogram from an image. A color histogram provides a
+count of how many times each color occurs in the image. The histogram is
+written into a user-provided container, which (for example) could be a <span
+ style="font-style: italic;"><vector></span> or a <span
+ style="font-style: italic;"><map></span>.  When a
+<map> is used, the <span style="font-style: italic;">Color</span>
+is used as the key so that quick lookups of usage counts for colors may
+be performed. Writing into a <span style="font-style: italic;"><map></span>
+may be slower than writing into a <span style="font-style: italic;"><vector></span>
+since the <span style="font-style: italic;"><map></span> sorts the
+entries (by color intensity) and checks for uniqueness. Each histogram
+entry is contained in type <span style="font-style: italic;">std::pair<Magick::Color,unsigned
+long></span><span style="font-style: italic;"> </span>with the first
+member of the pair being a <span style="font-style: italic;">Color,</span>
+and the second member of the pair being an '<span
+ style="font-style: italic;">unsigned long</span>'. Use the <span
+ style="font-style: italic;"><pair></span> "<span
+ style="font-style: italic;">first</span>" member to access the Color
+and the "<span style="font-style: italic;">second</span>" member to
+access the number of times the color occurs in the image.</p>
+<p>The template function declaration is as follows:<br />
+</p>
+<pre class="code">
+template <class Container >
+void colorHistogram( Container *histogram_, const Image image)
+</pre>
+<p>The following examples illustrate using both a <map> and a
+<vector> to retrieve the color histogram, and print out a
+formatted summary.<br />
+<br />
+Using <map>:<br />
+    <br />
+<pre class="code">
+ Image image("image.miff");
+ map<Color,unsigned long> histogram;
+ colorHistogram( &histogram, image );
+ std::map<Color,unsigned long>::const_iterator p=histogram.begin();
+ while (p != histogram.end())
+ {
+ cout << setw(10) << (int)p->second << ": ("

+ << setw(quantum_width) << (int)p->first.greenQuantum() << ","
+ << setw(quantum_width) << (int)p->first.blueQuantum() << ")"
+ << endl;
+ p++;
+ }
+</pre>
+<br />
+Using <vector>:<br />
+    <br />
+<pre class="code">
+ Image image("image.miff");
+ std::vector<std::pair<Color,unsigned long> > histogram;

+<p>The <i>TypeMetric</i> class provides the means to pass data from the Image class's TypeMetric method to the user. It provides information regarding font metrics such as ascent, descent, text width, text height, and maximum horizontal advance. The units of these font metrics are in pixels, and that the metrics are dependent on the current Image font (default Ghostscript's "Helvetica"), pointsize (default 12 points), and x/y resolution (default 72 DPI) settings.</p>
+<p>The pixel units may be converted to points (the standard resolution-independent measure used by the typesetting industry) via the following equation:</p>
+<pre class="text">
+size_points = (size_pixels * 72)/resolution
+</pre>
+<p>where resolution is in dots-per-inch (DPI). This means that at the default image resolution, there is one pixel per point.</p>
+<p>Note that a font's pointsize is only a first-order approximation of the font height (ascender + descender) in points. The relationship between the specified pointsize and the rendered font height is determined by the font designer.</p>
+<p>See <a href="http://freetype.sourceforge.net/freetype2/docs/glyphs/index.html">FreeType Glyph Conventions</a> for a detailed description of font metrics related issues.</p>

+ <h1 align="center"> MagickWand Examples in C</h1>\r
+\r
+ <p align="left">The programs on these pages show how to use the ImageMagick\r
+ MagickWand API. Each example is presented as a C \r
+ function, complete with headers, so that it can be copied to a file and \r
+ then included in your own C project. The code is written for Windows and was\r
+ compiled using MSVC V7 but, with a little tweaking, it should\r
+ also run on Linux.</p>\r
+ <p align="left">Some of the examples show a command line "program" and how to achieve the equivalent output using MagickWand.\r
+ By "equivalent" I mean that the program produces the \r
+ same image as the command line example - it won't necessarily be exactly how it is achieved by the convert program.\r
+ In some cases there is only one command line \r
+ example to replicate but in others there can be 3 or 4 commands which \r
+ build on each other to produce a final result. In most of these cases I \r
+ have created one C function which replicates all the commands but each \r
+ section of code will show how it relates to the original commands. \r
+ </p>\r
+ <p align="left"> \r
+ There is little or no error checking in the examples but\r
+ you should add your own where needed. For example, the MagickReadImage\r
+ function returns a true or false value depending upon whether the read succeeded and \r
+ you should check this using code similar to this:</p>\r
+ <blockquote dir="ltr" style="MARGIN-RIGHT: 0px">\r
+ <p align="left"> if(MagickReadImage(mw,"logo_gel.png") == \r
+ MagickFalse) {<br> // Handle \r
+ the error<br> }</p></blockquote>\r
+ <p align="left">You should note that there are a lot of \r
+ MagickWand functions which are declared as returning a boolean result \r
+ but which will \r
+ always return MagickTrue and are therefore not worth checking. \r
+ This is particularly true with the DrawingWand commands.\r
+ For example, even if DrawSetFont \r
+ doesn't find the font you specify, it will return MagickTrue because it will set \r
+ the font to your default system font.</p>\r
+\r
+\r
+\r
+ <p align="left">If you haven't used MagickWand \r
+ before, you should start with something easy such as this:\r

+ A simple starter. Convert the builtin logo: image to JPG.</FONT</p>\r
+ <p align="left">\r
+ It is easy to see that to make this convert \r
+ one of your own input files to another format you just replace "logo:" \r
+ with your input filename and replace "logo.jpg" with whatever output filename you \r
+ wish.</p>\r
+ <p align="left">The MagickReadImage function is very versatile. It will \r
+ accept a website URL which links to an image somewhere on the internet or \r
+ it can generate a plain coloured canvas using the "xc:" filename \r
+ convention. E.G. "xc:red" will create a red canvas and "xc:none" will \r
+ create a transparent canvas. If you use the "xc:" format you will usually \r
+ precede the read function with a call to MagickSetSize otherwise you will \r
+ get a 1x1 pixel image. It is worthwhile to read the "pseudo Image" and "Built-in Images" sections near the bottom of the\r
+ <a href="http://imagemagick.org/script/formats.php">ImageMagick Formats</a> page to see what other pseudo files are available.</p>\r
+ <p align="left">\r
+ Just in case you are deciding whether to use MagickCore instead of MagickWand, first\r
+ look at the simple example I showed in the previous paragraph and then look at\r
+ the equivalent written for MagickCore:\r
+ <br><FONT "SIZE=4"><br> <FONT COLOR="#000000">•</FONT> <!-- C!MagickCore.c!C --> <a href="MagickCore.htm">MagickCore.c</a> \r
+ The simple starter program written for MagickCore.</FONT></p>\r
+ <p align="left"> I think you'll \r
+ agree that even in this simple example, the MagickWand version is much easier to\r
+ read and write. \r

+Use ImageMagick<sup><a href="http://tarr.uspto.gov/servlet/tarr?regser=serial&entry=78333969">®</a></sup> to create, edit, compose, or convert bitmap images. It can read and write images in a variety of <a href="/script/../script/formats.php">formats</a> (over 200) including PNG, JPEG, JPEG-2000, GIF, TIFF, <a href="/script/../script/motion-picture.php">DPX</a>, <a href="/script/../script/high-dynamic-range.php">EXR</a>, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.</p>
+
+<p>The functionality of ImageMagick is typically utilized from the <a href="/script/../script/command-line-processing.php">command-line</a> or you can use the features from programs written in your favorite language.

Also, see <a href="http://www.fmwconcepts.com/imagemagick/">Fred's ImageMagick Scripts</a>: a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations. With <a href="https://github.com/dlemstra/Magick.NET">Magick.NET</a>, use ImageMagick without having to install ImageMagick on your server or desktop.</p>

+
+<p>Now that ImageMagick version 7 is released, we continue to maintain the legacy release of ImageMagick, version 6, at <a href="https://legacy.imagemagick.org/">https://legacy.imagemagick.org</a>. Learn how ImageMagick version 7 differs from previous versions with our <a href="/script/../script/porting.php">porting guide</a>.</p>
+
+<p>ImageMagick best practices <strong>strongly</strong> encourages you to configure a <a href="/script/../script/security-policy.php">security policy</a> that suits your local environment.</p>
+
+<p>As an analog to linear (RGB) and non-linear (sRGB) color colorspaces, as of ImageMagick 7.0.7-17, we introduce the LinearGray colorspace. Gray is non-linear grayscale and LinearGray is linear (e.g. -colorspace linear-gray).</p>
+
+<p>Want more performance from ImageMagick? Try these options:</p>
+
+<ul>
+<li>Add more memory to your system, see <a href="/script/../script/architecture.php#cache">the pixel cache</a>;</li>
+<li>Add more cores to your system (up to 20), see <a href="/script/../script/architecture.php#threads">threads of execution support</a>;</li>
+<li>push large images to a solid-state drive, see <a href="/script/../script/architecture.php#tera-pixel">large image support</a>.</li>
+</ul>
+<p>If these options are prohibitive, you can reduce the quality of the image results. The default build is Q16 HDRI. If you disable <a href="/script/../script/high-dynamic-range.php">HDRI</a>, you use half the memory and instead of predominately floating point operations, you use the typically more efficient integer operations. The tradeoff is reduced percision and you cannot process out of range pixel values (e.g. negative). If you build the Q8 non-HDRI version of ImageMagick, you again reduce the memory requirements in half-- and once again there is a tradeoff, even less percision and no out of range pixel values. For a Q8 non-HDRI build of ImageMagick, use these <code>configure</code> script options: <code>--with-quantum-depth=8 --disable-hdri</code>.</p>

+<p><a href="https://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a> shows how to use ImageMagick from the <a href="/script/../script/command-line-processing.php">command-line</a> to accomplish any of these tasks and much more. Also, see <a href="http://www.fmwconcepts.com/imagemagick/">Fred's ImageMagick Scripts</a>: a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations. With <a href="https://github.com/dlemstra/Magick.NET">Magick.NET</a>, use ImageMagick without having to install ImageMagick on your server or desktop.</p>

+<p>Now that ImageMagick version 7 is released, we continue to maintain the legacy release of ImageMagick, version 6, at <a href="https://legacy.imagemagick.org/">https://legacy.imagemagick.org</a>. Learn how ImageMagick version 7 differs from previous versions with our <a href="/script/../script/porting.php">porting guide</a>.</p>
+
+<p>ImageMagick best practices <strong>strongly</strong> encourages you to configure a <a href="/script/../script/security-policy.php">security policy</a> that suits your local environment.</p>
+
+<p>As an analog to linear (RGB) and non-linear (sRGB) color colorspaces, as of ImageMagick 7.0.7-17, we introduce the LinearGray colorspace. Gray is non-linear grayscale and LinearGray is linear (e.g. -colorspace linear-gray).</p>
+
+<p>Want more performance from ImageMagick? Try these options:</p>
+
+<ul>
+<li>Add more memory to your system, see <a href="/script/../script/architecture.php#cache">the pixel cache</a>;</li>
+<li>Add more cores to your system (up to 20), see <a href="/script/../script/architecture.php#threads">threads of execution support</a>;</li>
+<li>push large images to a solid-state drive, see <a href="/script/../script/architecture.php#tera-pixel">large image support</a>.</li>
+</ul>
+<p>If these options are prohibitive, you can reduce the quality of the image results. The default build is Q16 HDRI. If you disable <a href="/script/../script/high-dynamic-range.php">HDRI</a>, you use half the memory and instead of predominately floating point operations, you use the typically more efficient integer operations. The tradeoff is reduced percision and you cannot process out of range pixel values (e.g. negative). If you build the Q8 non-HDRI version of ImageMagick, you again reduce the memory requirements in half-- and once again there is a tradeoff, even less percision and no out of range pixel values. For a Q8 non-HDRI build of ImageMagick, use these <code>configure</code> script options: <code>--with-quantum-depth=8 --disable-hdri</code>.</p>
