2011-02-12 6.6.7-7 Cristy * Add support for the strip() and stripImage() STL methods. 2011-02-01 6.6.7-2 Cristy * Remove extra '+' in the geometry operator. 2010-06-16 6.6.2-2 Cristy * Patch for compile problem in mapImages of the STL header. 2010-02-21 6.5.9-10 Cristy * Add extent() to extend the image as defined by the geometry, gravity, and image background color. 2009-11-14 6.5.7-8 Cristy * Add forwardFourierTransform(), inverseFourierTransform(), and inverseFourierTransformImage() methods to implement forward and inverse discrete Fourier transform (DFT / IFT). 2009-09-28 6.5.6-6 Cristy * Add splice() method to splice the background color into the image. 2009-04-01 6.5.1-1 Cristy * Add virtualPixelMethod() method for image and options, required for distort(). 2008-09-09 6.4.3-7 Cristy * Use ImagesToBlob() rather than ImageToBlob() for writeImages(). 2007-10-02 6.3.6-7 Cristy * Define USE_MAP for Magick++/tests/colorHistogram.cpp (patch provided by albert chin ). 2007-04-10 6.3.3-7 Cristy * Add colorspaceType(RGBColorspace) to set RGB colorspace before an image read (useful to convert CMYK Potscript to RGB). 2006-02-05 6.3.2-3 Cristy * Clear exception in throwException() method. 2006-01-16 6.3.2-0 Cristy * Add extent() method to extend the image as defined by the geometry. 2003-12-04 Bob Friesenhahn * demo/analyze.cpp (main): New program to demonstrate using the 'analyze' process module. * demo/Makefile.am: Add rules to build analyze program. * lib/Image.cpp (process): New method to execute process modules. * lib/Image.cpp (attribute): New method to get and set named image attributes. 2003-10-01 Bob Friesenhahn * lib/Color.cpp: Ensure that all non-default constructors set opacity to opaque. 2003-09-17 Bob Friesenhahn * lib/Magick++/STL.h (colorHistogram): If map key is not const, then implicit type conversion occurs. Sun's C++ compiler doesn't seem to handle that. The map key is now defined as const in the insert arguments. 2003-09-01 Bob Friesenhahn * tests/Makefile.am: Add build support for colorHistogram.cpp. * tests/colorHistogram.cpp: New test program to test retrieving color histograms from the image using colorHistogram(). * lib/Magick++/STL.h (colorHistogram): Added new template function to retrieve a color histogram into a user-provided container. Verified to work when using STL and as the target container types. When is used, a user-specified color may be used to perform lookups in the map to obtain the usage count for that color. * lib/Color.cpp (operator >=): Insufficient resolution was being provided in order to reliably sort color objects in STL containers. The updated algorithm should be fail-safe. 2003-08-31 Bob Friesenhahn * lib/Image.cpp (channelDepth): New method to set or get the modulus depth for a specified channel. 2003-08-29 Bob Friesenhahn * lib/Magick++/Include.h (Magick): Added support for CopyCyanCompositeOp, CopyMagentaCompositeOp, CopyYellowCompositeOp, and CopyBlackCompositeOp, composition operators. 2003-08-12 Bob Friesenhahn * lib/Image.cpp (depth): Method now only updates the Image/ImageInfo depth member and retrieves the value of the Image depth member. (modulusDepth): New method to inspect the pixels for actual modulus depth, or update/reduce the pixels to a specified modulus depth. The depth method was performing this function so any code which depended on the depth method to compute or set the modulus depth should be updated to use modulusDepth() instead. 2003-08-03 Bob Friesenhahn * lib/Image.cpp (matte): If a new matte channel is created, initialize it to opaque. Likewise, if the matte channel is eliminated, initialize the unused channel to opaque. 2003-07-09 Bob Friesenhahn * demo/demo.cpp (main): Don't crop logo image. * * *.h, *.cpp: Include "Magick++/Include.h" before including any compiler or system header in order to ensure that LFS defines are properly applied. Inspired by patch from Albert Chin-A-Young. 2003-06-29 Bob Friesenhahn * lib/Magick++/Include.h: Needed to import ThrowLoggedException. * lib/Exception.cpp (throwException): Add originating source module, source line, and function name (if available) to exception report. This is useful in order to determine the exact conditions that lead to the exception being thrown. * lib/Magick++/Exception.h: Added ErrorCoder, WarningCoder, ErrorConfigure, WarningConfigure, ErrorDraw, WarningDraw, ErrorImage, WarningImage, ErrorMonitor, WarningMonitor, ErrorRegistry, WarningRegistry, ErrorStream, WarningStream, ErrorType, and WarningType, exception classes to support the full set of exceptions that ImageMagick can throw. 2003-06-22 Bob Friesenhahn * lib/CoderInfo.cpp (CoderInfo): Applied compilation fix from Mike Chiarappa to compile using Borland C++. 2003-06-06 Bob Friesenhahn * lib/Geometry.cpp (string): Throw an exception if a string is requested from an invalid geometry object. 2003-06-05 Bob Friesenhahn * lib/Geometry.cpp (operator =): If GetGeometry returns NoValue, then assign an invalid geometry object to cause an exception if the geometry is then used. 2003-06-04 Bob Friesenhahn * lib/Magick++/Exception.h (ErrorModule): Added class to handle module errors. * lib/Magick++/Exception.h (WarningModule) Added class to handle module warnings. 2003-05-30 Bob Friesenhahn * lib/Magick++/STL.h (coderInfoList): Use GetMagickInfoArray to access coder list. 2003-05-22 Bob Friesenhahn * lib/Magick++/STL.h (affineTransformImage): Add function object contributed by Vladimir Lukianov to apply an affine transform to the image. * lib/Image.cpp (affineTransform): Added method contributed by Vladimir Lukianov to apply an affine transform to the image. 2003-05-16 Bob Friesenhahn * lib/Magick++/Include.h: Decided to back out change which used the _VISUALC_ define to trigger inclusion of . 2003-05-14 Bob Friesenhahn * lib/Magick++/Include.h: If _VISUALC_ is defined, include . This ensures that this necessary header is included even if HAVE_SYS_TYPES_H is not defined in magick-config.h. 2003-05-04 Bob Friesenhahn * lib/Image.cpp (InitializeMagick): InitializeMagick is now a C++ function rather than a namespace inclusion. An atexit() handler is registered to invoke DestroyMagick when the program exits. Relying on static deconstruction to invoke DestroyMagick proved to be unreliable due to translation unit destruction uncertainty. 2003-04-15 Bob Friesenhahn * lib/Image.cpp (Image::Image (MagickCore::Image* image_)): Incorporated recommended fix from Jukka Manner to avoid a scenario which leaks an Options object. * tests/coalesceImages.cpp: Updated to use modified coalesceImages() interface. * lib/Magick++/STL.h (coalesceImages): Replaced implementation with one from Felix Heimbrecht. The template signature has changed to return a new image sequence. This template API silently ceased to funtion due to an ImageMagick CoalesceImages API change. 2003-03-30 Bob Friesenhahn * tests/readWriteBlob.cpp (main): Added check for stream read failure when reading blob data. (class myBlob): Use get rather than read. 2003-03-20 Bob Friesenhahn * tests/attributes.cpp : Change in the way that Magick++ retrieves density caused tests to fail. Density now defaults to 72x72 (ImageMagick default) rather than invalid. 2003-03-15 Bob Friesenhahn * demo/Makefile.am (CLEANFILES): Fix clean target to remove *_out.mvg output files as well. * demo/zoom.cpp: Added a command-line parser for dash arguments as well as an image "resample" capability. * lib/Image.cpp (density): Obtain density from Image rather than ImageInfo if the Image is valid. 2003-03-01 Bob Friesenhahn * lib/Makefile.am : Added rules to install ImageMagick++.pc. * lib/ImageMagick++.pc.in : Added pkgconfig file for -lImageMagick++. 2003-02-11 Bob Friesenhahn * lib/Image.cpp (colorSpace): Pass image->colorspace to TransformRGBColorspace. 2003-01-22 Bob Friesenhahn * lib/Magick++/STL.h (writeImages): Should have been invoking WriteImages rather than WriteImage! 2003-01-18 Bob Friesenhahn * lib/Magick++/Include.h: Add HSL and HWB colorspace transformation support. 2003-01-13 Bob Friesenhahn * lib/Image.cpp (colorSpace): Support colorspace transforms other than to and from RGB by translating to RGB as an intermediate step. 2002-11-24 Bob Friesenhahn * lib/Drawable.cpp: Added DrawablePushClipPath, DrawablePopClipPath, and DrawableClipPath. Implementation contributed by Vladimir . 2002-11-10 Bob Friesenhahn * lib/Image.cpp (colorMapSize): New method to set, or return the colormap size. 2002-11-08 Bob Friesenhahn * lib/Image.cpp (adaptiveThreshold): New method. 2002-10-01 Bob Friesenhahn * lib/Magick++/STL.h (coderInfoList): Intentionally ignore missing delegate exceptions. 2002-09-24 Bob Friesenhahn * lib/Options.cpp (textEncoding): Had forgotten to implement textEncoding! 2002-09-16 Bob Friesenhahn * lib/Color.cpp (Color): Use of 'new' and 'delete' in inlines was causing memory allocation/deallocation problems for users of the DLL build. Problem was identified by Marc Iwan. 2002-09-02 Bob Friesenhahn * lib/Image.cpp (compare): New method to compare current image with a reference image. 2002-08-19 Bob Friesenhahn * lib/Image.cpp (textEncoding): New method to allow setting the default text encoding (e.g. "UTF-8"). * lib/Drawable.cpp (DrawableText): Added an alternate constructor to allow specifying the text encoding (e.g. "UTF-8"). 2002-08-02 Bob Friesenhahn * Overall: Now compiles as a DLL using Visual C++. 2002-07-24 Bob Friesenhahn * lib/Image.cpp (profile): Added method to store, delete, or retrieve named application profiles. 2002-07-17 Bob Friesenhahn * lib/Image.cpp (type): Set the ImageInfo type attribute when setting the image type. If the type attribute is set to something other than UndefinedType (implying that the user has set a desired output image type), then return that as the image type, otherwise use GetImageType() to evaluate the image type. 2002-05-20 Bob Friesenhahn * lib/Drawable.cpp (DrawableTextUnderColor): New class to set the text undercolor. When text undercolor is set, a rectangle of the specified color is rendered under text annotations. 2002-05-19 Bob Friesenhahn * Magick++ library no longer depends on iostreams at all. 2002-04-28 Bob Friesenhahn * lib/Image.cpp (throwImageException): ExceptionInfo was not being properly initialized. This could cause some errors to cause an abort in error.c rather than throwing an exception. 2002-04-26 Bob Friesenhahn * lib/Image.cpp (draw): Use draw.h drawing APIs to draw on image. This means that MVG output no longer comes from code in Drawable.cpp. 2002-04-25 Bob Friesenhahn * lib/STL.cpp: Moved function object implementations from STL.h to STL.cpp. 2002-04-20 Bob Friesenhahn * lib/Image.cpp (getConstPixels): Changed offset parameter type from 'unsigned int' to 'int'. (getPixels): Changed offset parameter type from 'unsigned int' to 'int'. (setPixels): Changed offset parameter type from 'unsigned int' to 'int'. (cacheThreshold): Changed argument type from 'const long' to 'const int'. (matteFloodfill): Changed offset parameter type from 'const long' to 'const int'. * lib/Pixels.cpp (getConst): New method to return read-only pixels. (get): Offset parameter types changed from 'unsigned int' to 'int'. 2002-04-19 Bob Friesenhahn * lib/Magick++/Drawable.h (DrawableDashOffset): Change dashoffset type to 'double' rather than 'unsigned int' in order to match ImageMagick. * lib/Drawable.cpp (DrawableDashArray): Change dasharray type to 'double' rather than 'unsigned int' in order to match ImageMagick. Previous 'unsigned int' methods remain for compatability reasons. 2002-04-14 Bob Friesenhahn * lib/Drawable.cpp (DrawableCompositeImage): Always output composite images as inlined Base64. 2002-04-13 Bob Friesenhahn * lib/Drawable.cpp (DrawableCompositeImage): If magick attribute string is specified, then composite image is supplied to ImageMagick as inlined Base64 rather than by MPRI reference. * lib/Blob.cpp (base64): Added methods to update Blob with data from Base64-encoded string, or to return a Base64-encoded string from Blob. Still needs documentation. 2002-04-09 Dom Lachowicz * lib/Image.cpp (Image::ping): Added PingBlob function 2002-04-07 Bob Friesenhahn * lib/Drawable.cpp (DrawableDashArray::operator=): Added missing assignment operator (fixes a bug).

(chromaBluePrimary): Changed argument type from float to double. (chromaGreenPrimary): Changed argument type from float to double. (chromaRedPrimary): Changed argument type from float to double. (chromaWhitePoint): Changed argument type from float to double. (getConstPixels): Changed argument type of x_ & _y from 'int' to 'unsigned int'. (getPixels): Changed argument type of x_ & _y from 'int' to 'unsigned int'. 2002-04-05 Bob Friesenhahn * lib/Image.cpp (debug): Added method to set ImageMagick debug flag so that it prints debugging information while it runs. 2002-04-03 Bob Friesenhahn * lib/Drawable.cpp: Fixed a bunch of bugs related to DrawableCompositeImage, DrawableFont, and inconsistencies discovered by Gimpel lint. 2002-04-02 Bob Friesenhahn * lib/Image.cpp (draw): Properly delimit individual drawing commands so that MVG output is correct. 2002-03-30 Bob Friesenhahn * lib/Drawable.cpp (DrawableViewbox): MVG syntax wasn't correct. * lib/Image.cpp (draw): Fix algorithm used to append newlines to MVG commands so that draw() may be invoked multiple times while still producing valid MVG. 2002-03-29 Bob Friesenhahn * lib/Drawable.cpp (DrawableViewbox): New class to allow setting the MVG output size. 2002-03-26 Bob Friesenhahn * lib/Drawable.cpp (print): Changed "mpr:" to "mpri:" in order to *finally* get DrawableCompositeImage to work as intended. * lib/Image.cpp (registerId): Bugfix. Register using sizeof(MagickCore::Image) rather than sizeof(Image). 2002-03-26 Bob Friesenhahn * lib/Drawable.cpp (DrawableCompositeImage): Had failed to initialize width and height in object to image width and height. 2002-02-28 Bob Friesenhahn * lib/Magick++/STL.h (endianImage): New class to specify the endian option for formats which support this notion (e.g. TIFF). * lib/Image.cpp (endian): New method to specify the endian option for formats which support this notion (e.g. TIFF). 2002-02-11 Bob Friesenhahn * lib/Drawable.cpp (DrawableFont): Support specifying a font via font-family, font-style, font-weight, and font-stretch. Wildcard matches are supported. 2002-02-06 Bob Friesenhahn * lib/Image.cpp (charcoal): Replace Magick++'s charcoal effect with the output of ImageMagick's CharcoalImage function in order to ensure consistency. * lib/Magick++/CoderInfo.h (MatchType): Scope the MatchType enumeration to the CoderInfo class so these enumeration names can be re-used elsewhere without conflict. This results in a minor API change to the coderInfoList() templated function since enumerations must be specified like "CoderInfo::TrueMatch" rather than just "TrueMatch". Hopefully not a problem since this function and class were not documented outside of the headers until this release. 2002-02-05 Bob Friesenhahn * lib/Magick++/STL.h (coderInfoList): Finally wrote some documentation. 2002-01-26 Bob Friesenhahn * lib/Options.cpp : Use DestroyImageList() rather than DestroyImage(). * lib/Geometry.cpp (operator =): Use GetPageGeometry() rather than PostscriptGeometry() to parse geometry specifications containing a page size. 2002-01-21 Bob Friesenhahn * Remove bogus cast of blob data in readImages(). 2002-01-20 Bob Friesenhahn * lib/Image.cpp (throwImageException): Throwing exceptions was leaking memory. * lib/Exception.cpp (throwException): Throwing exceptions was leaking memory. * lib/Image.cpp (replaceImage): Updated to properly handle registration ids. (modifyImage): Updated to properly handle registration ids. 2002-01-15 Bob Friesenhahn * lib/Drawable.cpp (Magick::DrawableGravity::print): Bugfix. Remove "Gravity" from the end of each gravity specification string.

(DrawablePopPattern): Support popping (terminating) pattern definition. 2001-12-26 Bob Friesenhahn * lib/Drawable.cpp (DrawableCompositeImage): Read image immediately if provided by filename, register with peristent registry, and pass as perisistant image type. (DrawableCompositeImage): Support specifying Image in memory. Passed as perisistant image type. 2001-12-24 Bob Friesenhahn * lib/Color.cpp (operator std::string): Color string buffer was one character too short! 2001-12-20 Bob Friesenhahn * lib/TypeMetric.cpp (characterWidth): Eliminate method. (characterHeight): Eliminate method. (all remaining methods): Change return type to 'double'. Fix documentation in source files to reflect that units are in pixels rather than points.

ImageMagick bug #975. * lib/Image.cpp (draw): Delete ostrstream data when it is no longer needed. ImageMagick bug #988. 2001-11-07 Bob Friesenhahn * lib/Image.cpp (pixelColor): Implementation didn't handle pixels indexes correctly. Now it does. 2001-11-04 Bob Friesenhahn * lib/Image.cpp (matteFloodfill): Coordinates are long values. (floodFillOpacity): New method to floodfill opacity across pixels matching color (within fuzz-factor) at point. Similar to matteFloodfill except that color is selected from starting point. 2001-10-29 Bob Friesenhahn * lib/Image.cpp (strokeDashArray): Change to type double.

(fillColor): New method. * lib/Image.cpp (replaceImage): Revised logic so that an inValid image should be returned if a NULL pointer is passed. Before this change the existing image was preserved. (label): Work-around ImageMagick SetImageAttribute bug. 2001-01-10 Bob Friesenhahn * lib/Image.cpp : Adjusted to ImageMagick animation parameter API change. 2000-12-31 Bob Friesenhahn * lib/Drawable.cpp (DrawableCompositeImage): Support specifying composition rule. 2000-12-27 Bob Friesenhahn * lib/Image.cpp (draw): Bugfix - the primitive string was not properly null terminated. It is a wonder that the code usually worked at all. Thanks to afatela@marktest.pt for reporting it. 2000-12-24 Bob Friesenhahn * lib/Magick++/STL.h (deconstructImages): New STL function for deconstructing an image list to assist with creating an animation. (mosaicImages): New STL function for inlaying an image list to form a single coherent picture. 2000-12-17 Bob Friesenhahn * lib/Image.cpp (convolve): New method to convolve image using user-supplied convolution matrix. (unsharpmask): New method to replace image with a sharpened version of the original image using the unsharp mask algorithm. 2000-12-14 Bob Friesenhahn * : Adapted to ImageMagick API change which eliminates AnnotateInfo. 2000-12-10 Bob Friesenhahn * lib/Magick++/STL.h (annotateImage): Brought into sync with annotate methods in Image. 2000-12-09 Bob Friesenhahn * lib/Image.cpp (annotate): Usage of Geometry parameter was incorrect. Geometry parameter is used to specify bounding area. This changes the interpretation for two of the annotate methods (which probably weren't usable before). 2000-11-29 Bob Friesenhahn * lib/Magick++/Color.h (alphaQuantum): Bugfix. Due to change in treatment of opacity member, alphaQuantum() was not allowing value to be set. 2000-11-25 Bob Friesenhahn * lib/Drawable.cpp (DrawableFillRule): New class to specify fill rule (see SVG's fill-rule).

(transformReset): New method to reset transformation to default. * lib/Drawable.cpp (DrawablePath): New class for drawing SVG-style vector paths. (PathArcArgs): New class. Argument for PathArcArgs & PathArcAbs. (PathArcAbs): New class. Draw arc using absolute coordinates. (PathArcRel): New class. Draw arc using relative coordinates. (PathClosePath): New class. Close drawing path. (PathCurvetoArgs): New class. Argument class for PathCurvetoAbs & PathCurvetoRel. (PathCurvetoAbs): New class. Cubic bezier, absolute coordinates (PathCurvetoRel): New class. Cubic bezier, relative coordinates (PathSmoothCurvetoAbs): New class. Cubic bezier, absolute coordinates (PathSmoothCurvetoRel): New class. Cubic bezier, relative coordinates (PathQuadraticCurvetoArgs): New class. Argument class for PathQuadraticCurvetoAbs and PathQuadraticCurvetoRel. (PathQuadraticCurvetoAbs): New class. Quadratic bezier, absolute coordinates (PathQuadraticCurvetoRel): New class. Quadratic bezier, relative coordinates (PathSmoothQuadraticCurvetoAbs): New class.

(PathLinetoVerticalRel): New class. Vertical lineto, relative coordinates. (PathMovetoAbs): New class. Moveto, absolute coordinates (PathMovetoRel): New class. Moveto, relative coordinates 2000-10-10 Bob Friesenhahn * lib/Drawable.cpp (DrawableSkewX): New object to apply skew in X direction. (DrawableSkewY): New object to apply skew in Y direction. 2000-10-09 Bob Friesenhahn * lib/Image.cpp (edge): Change argument from 'unsigned int' to 'double' in order to match ImageMagick API. 2000-10-08 Bob Friesenhahn * lib/Drawable.cpp (DrawableCompositeImage): Renamed from DrawableImage. (DrawableTextDecoration): Renamed form DrawableDecoration. (all-classes): Complete re-write to write the drawing command to a stream when draw() is invoked rather than at object construction time. This may be somewhat slower for individual draw operations but should be at least as fast for lists of drawing commands, and is more flexible going into the future. Drawable classes now inherit from DrawableBase but are passed into STL lists and Image draw() methods via the surrogate class Drawable. The upshot of all this is that the existing published API has not been altered but things work much differently under the covers. 2000-10-05 Bob Friesenhahn * lib/Drawable.cpp (DrawableStrokeColor): Renamed from DrawableStroke (DrawableFillColor): Renamed from DrawableFill (DrawableRotation): New class to influence object rotation. (DrawableScaling): New class to influence object scaling. (DrawableTranslation): New class to influence object translation. 2000-10-04 Bob Friesenhahn * lib/Drawable.cpp (DrawableAffine): New class to influence object scaling, rotation, and translation (as defined by SVG XML). (DrawableAngle): New class to influence drawing angle. (DrawableDecoration): New class to influence text decoration such as underline. (DrawableFill): New class to set object filling color. (DrawableFillOpacity): New class to set opacity to use when filling object. (DrawableFont::): New class to set font. (DrawableGravity): New class to set text placement gravity. (DrawablePointSize): New class to set font point size. (DrawableStroke): New class to set drawing stroke color. (DrawableStrokeOpacity): New class to set drawing stroke opacity. (DrawableStrokeWidth): New class to set drawing stroke width. 2000-10-03 Bob Friesenhahn * lib/Drawable.cpp (DrawableImage): Added width and height parameters to specify size to scale rendered image to. This is actually a bug-fix since it seems that the correct drawing command was no longer being generated. 2000-09-30 Bob Friesenhahn * lib/Image.cpp (read): New overloaded method to read an image based on an array of raw pixels, of specified type and mapping, in memory. (write): New overloaded method to write image to an array of pixels, of specified type and mapping. (Image): New overloaded constructor to construct an image based on an array of raw pixels, of specified type and mapping, in memory. 2000-09-27 Bob Friesenhahn * lib/Image.cpp (colorize): API change to match change in ImageMagick. Now accepts percentage of red, green, and blue to colorize with using specified pen color. 2000-09-20 Bob Friesenhahn * lib/Magick++/Drawable.h: Reverted Coordinate implemenation back from and STL pair based implementation to a simple class. Maybe this will improve portability. It is more understandable anyway. 2000-09-18 Bob Friesenhahn * lib/Options.cpp : Bugfix. Some DrawInfo attributes were not being updated. This lead to options like fontPointsize not changing the font. 2000-08-26 Bob Friesenhahn * lib/Magick++/STL.h (blurImage, charcoalImage, embossImage, sharpenImage): Expand order_ argument to radius_ & sigma_ arguments for more control (matches ImageMagick API change). * lib/Image.cpp (blur, charcoal, emboss, sharpen): Expand order_ argument to radius_ & sigma_ arguments for more control (matches ImageMagick API change). 2000-08-24 Bob Friesenhahn * lib/Image.cpp (read): Check returned Image for embedded exception, as well as the existing parameter check. This fixes the bug that warnings are not reported. 2000-07-26 Bob Friesenhahn * test/*.cpp demo/*.cpp: Added call to MagickIncarnate() to set ImageMagick install location for Windows. Hopefully this hack can be removed someday. 2000-07-20 Bob Friesenhahn * lib/Image.cpp (colorFuzz): Changed type to 'double' from 'unsigned int' to match change in ImageMagick. * lib/Color.cpp (Color*): Added copy constructor from base class. (operator =): Added assignment operator from base class. 2000-06-28 Bob Friesenhahn * lib/Magick++/Include.h : Changed enumeration FilterType to FilterTypes, and QuantumTypes to QuantumType in order to match last-minute API change in ImageMagick. 2000-06-22 Bob Friesenhahn * lib/Magick++/Pixels.cpp (indexes): Bugfix, use GetCacheViewIndexes() rather than GetIndexes(). 2000-05-23 Bob Friesenhahn * lib/Magick++/Montage.h (gravity): Type of gravity_ argument, and return value changed from 'unsigned int' to GravityType. 2000-04-17 Bob Friesenhahn * lib/Drawable.cpp (DrawableArc, DrawableBezier, DrawablePolyline, RoundRectangle): Added support for new drawing objects. 2000-04-16 Bob Friesenhahn * lib/Drawable.cpp: Removed all public methods which accept Coordinate arguments except those that accept lists of Coordinates. Converted remaining drawable object methods into individual classes which inherit from Drawable (e.g. "circle" becomes "DrawableCircle"). The constructor for each class is compatible with the original method. This results in annoying changes to user code but provides more implementation flexibility. 2000-04-09 Bob Friesenhahn * lib/Drawable.cpp (fillEllipse,fillRectangle,fillCircle,fillPolygon): Removed methods. Object filling is now based on whether fillColor or penTexture are valid or not. This reflects ImageMagick internal changes. * lib/Image.cpp (fillColor): New method to specify fill color when drawing objects. (strokeColor): New method to specify outline color when drawing objects. (penColor): Setting penColor now sets fillColor and strokeColor. Getting penColor retrieves the value of strokeColor. This supports backwards compatability. 2000-03-28 Bob Friesenhahn * lib/Image.cpp (lineWidth): Type changed from unsigned int to double. 2000-03-08 Bob Friesenhahn * lib/Magick++/STL.h (Magick): 2000-03-07 Bob Friesenhahn * lib/Magick++/STL.h (blurImage,charcoalImage,edgeImage,embossImage, reduceNoiseImage,sharpenImage): Modified to support order of the pixel neighborhood. Backward compatable function objects constructors are provided for embossImage, and reduceNoiseImage. * lib/Image.cpp (blur,charcoal,edge,emboss,reduceNoise,sharpen): Now accept unsigned int argument which represents the order of the pixel neighborhood (e.g. 3). This is not a backwards compatable change, however, backward compatable methods are provided for emboss, and reduceNoise. 2000-03-02 Bob Friesenhahn * lib/Magick++/Pixels.h (Pixels): Moved Image pixel methods to Pixels class. 2000-02-29 Bob Friesenhahn * lib/Image.cpp (annotate): Re-wrote to improve performance. (draw): Re-wrote to improve performance. 2000-02-26 Bob Friesenhahn * lib/Drawable.cpp (text): Bugfix: support spaces in annotation text. 2000-02-23 Bob Friesenhahn * lib/Magick++/STL.h (gaussianBlurImage): New function object to Gaussian blur image. * lib/Image.cpp (gaussianBlur): New method to Gaussian blur image. 2000-02-16 Bob Friesenhahn * lib/Image.cpp : Call-back based LastError class is eliminated in favor of ImageMagick 5.2's re-entrant ExceptionInfo reporting. This should make Magick++ thread safe under Win32. 2000-02-08 Bob Friesenhahn * lib/Image.cpp (floodFillTexture): Fixed bug due to pixel pointer becoming invalid in ImageMagick function. 2000-01-24 Bob Friesenhahn * lib/Image.cpp : Added locking to reference counting to ensure thread (pthread) safety. * lib/Blob.cpp : Added locking to reference counting to ensure thread (pthread) safety. * lib/LastError.cpp: Added support for thread specific data (pthreads) so that error reporting is thread safe. * lib/Magick++/Thread.h: Added thread wrapper class to provide thread-safe locking (pthreads) to Magick++. 2000-01-19 Bob Friesenhahn * lib/Image.cpp: Added methods getPixels, setPixels, syncPixels, readPixels, and writePixels, in order to provide low-level access to Image pixels. This approach (direct wrapper around ImageMagick functions) does not mean that the planned object-oriented wrapper has been forgotten, only that this wrapper is not ready yet, and users need to manipulate pixels *now*. 2000-01-16 Bob Friesenhahn * lib/LastError.cpp: Complete re-implementation of LastError so that it hides its implementation. Also assures that all memory is explicitly deallocated at program exit to avoid the appearance of a leak. 2000-01-11 Bob Friesenhahn * lib/Image.cpp (size): Bug-fix. Set image columns and rows as well as image options columns and rows. * lib/Image.cpp :Depth parameters are now all unsigned in for consistency. * lib/Image.cpp (write): Parameters for writing Blobs re-arranged again to hopefully be more sensible. * lib/Magick++/STL.h: Bug-fix. Re-number scenes from zero when linking image range in container into a list. This provides expected results. 1999-12-31 Bob Friesenhahn * lib/Image.cpp (write): Additional overloaded methods for BLOBs. (read): Additional overloaded methods for BLOBs. Re-ordered parameters for one existing method. (Image): Additional overloaded methods for BLOBs. Re-ordered parameters for one existing method. 1999-12-28 Bob Friesenhahn * lib/Image.cpp (floodFillTexture): Changed coordinates to unsigned. 1999-12-21 Bob Friesenhahn * lib/Image.cpp (medianFilter): New method. 1999-12-18 Bob Friesenhahn * lib/Image.cpp (density): Bug fix. Was not setting image x & y density. 1999-11-30 Bob Friesenhahn * lib/Image.cpp (page): psPageSize() is renamed to page() and now properly returns the attribute from the image. 1999-11-25 Bob Friesenhahn * lib/Image.cpp: Rename transformColorSpace() to colorSpace(). Added colorSpace() accessor method. 1999-11-24 Bob Friesenhahn * lib/Color.cpp: Re-implemented PixelPacket pointer so that it is never NULL and added a 'valid' field for tracking object validity. 1999-11-13 Bob Friesenhahn * lib/Image.cpp (quantizeError): Eliminated method. 1999-11-10 Bob Friesenhahn * lib/Image.cpp (annotate & draw): Changed implementation to reflect change to the way AnnotateInfo is managed by ImageMagick. 1999-11-07 Bob Friesenhahn * lib/Image.cpp (cacheThreshold): New method to set the pixel cache threshold. * lib/Magick++/Include.h (Magick): Added new enumerations from classify.h. 1999-10-28 Bob Friesenhahn * lib/Magick++/Options.h (fontPointsize): Argument is now a double to match change in ImageMagick. * lib/Image.cpp (fontPointsize): Argument is now a double to match change in ImageMagick. 1999-10-21 Bob Friesenhahn * lib/Blob.cpp (BlobRef): Bugfix -- start blob reference count at one rather than zero. 1999-10-19 Bob Friesenhahn * lib/Image.cpp (Image): Fixed Image constructors from Blob. The image reference was not being instantiated as it should have been, causing a crash. 1999-10-05 Bob Friesenhahn * lib/Blob.cpp: All blob length parameters are now of type size_t. * lib/Image.cpp (write): Length estimate is now of type size_t. 1999-09-20 Bob Friesenhahn * lib/Image.cpp (rotate): No longer accepts a crop option since ImageMagick no longer supports this. (shear): No longer accepts a crop option since ImageMagick no longer supports this. 1999-09-18 Bob Friesenhahn * lib/Image.cpp: (rotate): No longer accepts sharpen argument. User must sharpen seperately if desired. This change is due to a similar change in ImageMagick 5.0. (condense): Removed method. (uncondense): Removed method. (condensed): Removed method. (pixelColor): Adapted to 5.0. * lib/Magick++/Color.h : Rewrote to efficiently use ImageMagick 5.0's PixelPacket color representation. * lib/Color.cpp : Rewrote to efficiently use ImageMagick 5.0's PixelPacket color representation. 1999-09-12 Bob Friesenhahn * lib/Image.cpp (condensed): Bug fix. The condensed() method was returning the opposite bool value than it should. Oops! 1999-09-07 Bob Friesenhahn * lib/Magick++/Include.h (MagickCore): Eliminated requirement for including . 1999-08-07 Bob Friesenhahn * lib/Image.cpp: Added accessor methods for other key ImageMagick structs. * lib/Options.cpp (penTexture): Fixed bug with removing texture caused by change in Image constructor. * lib/Image.cpp: Changed strategy such that an Image containing a null MagickCore::Image pointer is never constructed except for under error conditions. Removed existing checks for null image pointer on attribute methods. Use image() and constImage() accessor methods as part of Image implementation in order to clean-up code and ensure const-correctness. 1999-08-03 Bob Friesenhahn * lib/Magick++/STL.h (Magick): Added STL function readImages(). Not tested yet. (Magick): Added STL function writeImages(). Not tested yet. * lib/Image.cpp: Removed support for 'text' attribute as this is no longer present in ImageMagick as of 4.2.8. 1999-07-21 Bob Friesenhahn * lib/Image.cpp (condense): Skip condensing image if already condensed. (uncondense): Skip uncondensing image if not condensed. (condensed): New method to test if image is condensed. (classType): New method which supports conversion of the image storage class. May result in loss of color information (quantization is used) if a DirectClass image is converted to PseudoClass. 1999-07-18 Bob Friesenhahn * lib/Magick++/Color.h (Magick::Color): Color parameters are now stored in a MagickCore::RunlengthPacket structure which is referenced via a pointer. This structure is either allocated by a Magick::Color constructor or passed as an argument to a Magick::Color constructor so that it may refer to a MagickCore::Image pixel. The owner of the structure is managed so that the structure is only deleted if it was allocated by Magick::Color. 1999-07-09 Bob Friesenhahn * overall : Removed 'Magick' prefix from all source file names. Moved class headers to Magick++ subdirectory. This should not break any code using the documented interface (via Magick++.h). 1999-07-08 Bob Friesenhahn * lib/MagickImage.cpp (composite): Support composition placement by gravity like PerlMagick does. 1999-07-07 Bob Friesenhahn * lib/MagickImage.cpp (Image): Added constructors to construct an Image from a BLOB. 1999-07-06 Bob Friesenhahn * tests/manipulate.cpp (main): Wrote a basic sanity test for reading and writing BLOBS. 1999-06-21 Bob Friesenhahn * lib/MagickImage.cpp (read): Added support for reading an encoded image stored in a BLOB. Uses new ImageMagick APIs introduced on July 21, 1999. (write): Added support for writing an encoded image to a BLOB. 1999-06-16 Bob Friesenhahn * lib/MagickInclude.h : Use new interface to ImageMagick to avoid namespace-induced problems. * configure.in : CPPFLAGS and LDFLAGS specified via the environment take precidence over flags from Magick-config. 1999-05-31 Bob Friesenhahn * lib/MagickSTL.h (mapImages): New algorithm to map the sequence of images to the color map of a provided image. (quantizeImages): New algorithm to quantize a sequence of images to a common color map. 1999-05-24 Bob Friesenhahn * lib/MagickBlob.cpp (updateNoCopy): New method to allow derived classes to insert data into the base class without making a copy of the data. This represents a transfer of ownership of the data from the derived class to the base class. 1999-05-23 Bob Friesenhahn * lib/MagickColor.cpp (operator =): Adapted to new ImageMagick 4.2.6 as of 5/23/99 which removes X11 compatability functions. * lib/MagickGeometry.cpp (operator =): Adapted to new ImageMagick 4.2.6 as of 5/23/99 which removes X11 compatability functions. 1999-05-17 Bob Friesenhahn * lib/MagickBlob.cpp (Blob): Support default constructor for Blob. 1999-05-16 Bob Friesenhahn * lib/MagickSTL.h (transformColorSpaceImage): New unary function object to invoke transformColorSpace on STL container object. * lib/MagickImage.cpp (transformColorSpace): New method to transform the image data to a new colorspace. 1999-05-15 Bob Friesenhahn * lib/MagickImage.cpp (ping): Re-implemented to match (requested) API change in ImageMagick 4.2.5. Method signature has changed to be like 'read'. (annotate): Added two new overloaded methods for text annotation in order to support the new rotated text capability in ImageMagick 4.2.5. To accomplish this, the default for gravity had to be removed from several methods. This may impact existing code. Still not sure if this is the best set of method signatures. 1999-05-13 Bob Friesenhahn * lib/MagickImage.cpp (ping): New method to obtain image size in bytes and geometry without the overhead of reading the complete image. (uncondense): New method to uncompress run-length encoded pixels into a simple array to make them easy to operate on. 1999-05-12 Bob Friesenhahn * lib/MagickImage.cpp (comment): Passing an empty string as the comment results in no comment at all rather than a comment with no data. 1999-05-11 Bob Friesenhahn * lib/MagickImage.cpp (iccColorProfile): Implemented method to set ICC color profile from opaque object in memory (must be formatted outside of Magick++). (iptcProfile): Implemented method to set IPTC profile from opaque object in memory (must be formatted outside of Magick++). * lib/MagickBlob.cpp: New class to support managing user-supplied opaque Binary Large OBjects (BLOBS) in the API. Reference counted to improve semantics and to possibly reduce memory consumption. 1999-05-01 Bob Friesenhahn * lib/Makefile.am (libMagick): Updated to use libtool 1.3 so that shared library can be built. 1999-04-25 Bob Friesenhahn * lib/MagickImage.cpp (montageGeometry): Return Magick::Geometry rather than std::string. 1999-04-19 Bob Friesenhahn * lib/MagickColor.cpp (alpha): Added support for setting alpha via scaled-double to the Color class. The new method name is 'alpha'. 1999-04-13 Bob Friesenhahn * lib/MagickColor.cpp: Added support for setting an alpha value (unscaled Quantum only) for use on DirectColor images that have matte enabled. This requires ImageMagick 4.2.2 dated April 13, 1999 or later to compile since Cristy added a special flag to allow testing to see if the user has specified an opacity value: "I added XColorFlags to magick/classify.h. If DoMatte is set in color->flags then the opacity value is valid in color->pixel." 1999-04-11 Bob Friesenhahn * demo/flip.cpp (main): New file. Demonstrates use of flipImage function object as well as morphImages algorithm. 1999-04-10 Bob Friesenhahn * tests/color.cpp : New file to support testing the Magick::Color classes. * lib/MagickOptions.cpp: The ImageInfo filter member is now ignored by ImageMagick (as of ImageMagick 4.2.2 April 10, 1998) so support for setting it is removed. The Image filter member is still updated. According to Cristy, this ImageMagick version removes automatic sharpening of resized images. The blur member is added to the Image structure. A blur value < 1 causes the image to be sharpened when resizing while a value > 1 leaves the image blurry. Magick++ does not yet support the blur member.
