[imagemagick] / Magick++ / ChangeLog

2009-04-01  6.5.1-1 Cristy  <quetzlzacatenango@image...>
  * Add virtualPixelMethod() method for image and options, required for
    distort().

2008-09-09  6.4.3-7 Cristy  <quetzlzacatenango@image...>
  * Use ImagesToBlob() rather than ImageToBlob() for writeImages().

2007-10-02  6.3.6-7 Cristy  <quetzlzacatenango@image...>
  * Define USE_MAP for Magick++/tests/colorHistogram.cpp (patch provided by
    albert chin <china@thewr...>).

2007-04-10  6.3.3-7 Cristy  <quetzlzacatenango@image...>
  * 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  <quetzlzacatenango@image...>
  * Clear exception in throwException() method.

2006-01-16  6.3.2-0 Cristy  <quetzlzacatenango@image...>
  * Add extent() method to extend the image as defined by the geometry.

2003-12-04  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Color.cpp: Ensure that all non-default constructors set
        opacity to opaque.

2003-09-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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 <vector> and <map> as the target
        container types.  When <map> 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (channelDepth): New method to set or get the
        modulus depth for a specified channel.

2003-08-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Include.h (Magick): Added support for
        CopyCyanCompositeOp, CopyMagentaCompositeOp,
        CopyYellowCompositeOp, and CopyBlackCompositeOp, composition
        operators.

2003-08-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/CoderInfo.cpp (CoderInfo): Applied compilation fix from
        Mike Chiarappa to compile using Borland C++.

2003-06-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Geometry.cpp (string): Throw an exception if a string is
        requested from an invalid geometry object.

2003-06-05  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/STL.h (coderInfoList): Use GetMagickInfoArray to
        access coder list.

2003-05-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Include.h: Decided to back out change
        which used the _VISUALC_ define to trigger inclusion of
        <sys/types.h>.

2003-05-14  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Include.h: If _VISUALC_ is defined,
        include <sys/types.h>. 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Makefile.am : Added rules to install ImageMagick++.pc.
        * lib/ImageMagick++.pc.in : Added pkgconfig file for
        -lImageMagick++.

2003-02-11  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (colorSpace): Pass image->colorspace to
        TransformRGBColorspace.

2003-01-22  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/STL.h (writeImages): Should have been invoking
        WriteImages rather than WriteImage!

2003-01-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Include.h: Add HSL and HWB colorspace
        transformation support.

2003-01-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp: Added DrawablePushClipPath,
        DrawablePopClipPath, and DrawableClipPath.  Implementation
        contributed by Vladimir <lvm@integrum.ru>.

2002-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (colorMapSize): New method to set, or return
        the colormap size.

2002-11-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (adaptiveThreshold): New method.

2002-10-01  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/STL.h (coderInfoList): Intentionally ignore missing
        delegate exceptions.

2002-09-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Options.cpp (textEncoding): Had forgotten to implement
        textEncoding!

2002-09-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (compare): New method to compare current image
        with a reference image.

2002-08-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * Overall: Now compiles as a DLL using Visual C++.

2002-07-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (profile): Added method to store, delete, or
        retrieve named application profiles.

2002-07-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * Magick++ library no longer depends on iostreams at all.

2002-04-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/STL.cpp: Moved function object implementations from STL.h to
        STL.cpp.

2002-04-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (DrawableCompositeImage): Always output
        composite images as inlined Base64.

2002-04-13  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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    <cinamod@hotmail.com>

        * lib/Image.cpp (Image::ping): Added PingBlob function
        
2002-04-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (DrawableDashArray::operator=): Added missing
        assignment operator (fixes a bug).
        (DrawableDashArray::DrawableDashArray): Added missing copy
        constructor (fixes a bug).

        * lib/Image.cpp (oilPaint): Changed argument type from unsigned
        int to double.
        (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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp: Fixed a bunch of bugs related to
        DrawableCompositeImage, DrawableFont, and inconsistencies
        discovered by Gimpel lint.

2002-04-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (draw): Properly delimit individual drawing
        commands so that MVG output is correct.

2002-03-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (DrawableViewbox): New class to allow setting
        the MVG output size.

2002-03-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (DrawableCompositeImage): Had failed to
        initialize width and height in object to image width and height.

2002-02-28  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/STL.h (coderInfoList): Finally wrote some
        documentation.

2002-01-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

       * Remove bogus cast of blob data in readImages().

2002-01-20  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (Magick::DrawableGravity::print):
        Bugfix. Remove "Gravity" from the end of each gravity
        specification string.  Reported as PR#1084 by stefan@dotify.com.

2002-01-12  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp, Magick++/Include.h: Use DestroyImageList() rather
        than DestroyImages().

2002-01-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Options.h (antiAlias): Bugfix, set
        drawInfo->text_antialias to control text antialiasing.

2002-01-02  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Include.h : Imported new composition operators to
        namespace: NoCompositeOp, DarkenCompositeOp, LightenCompositeOp,

        properly null terminated. It is a wonder that the code usually
        worked at all.  Thanks to afatela@marktest.pt for reporting it.

        annotate methods in Image.

2000-12-09  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Color.h (alphaQuantum): Bugfix.  Due to change in

        (DrawableTextDecoration): Renamed form DrawableDecoration.
        (all-classes): Complete re-write to write the drawing command to a

        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.

        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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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 <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Pixels.cpp (indexes): Bugfix, use GetCacheViewIndexes()
        rather than GetIndexes().

2000-05-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Montage.h (gravity): Type of gravity_ argument, and
        return value changed from 'unsigned int' to GravityType.

2000-04-17  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (DrawableArc, DrawableBezier, DrawablePolyline,
        RoundRectangle): Added support for new drawing objects.

2000-04-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (lineWidth): Type changed from unsigned int to double.

2000-03-08  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/STL.h (Magick): 

2000-03-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Pixels.h (Pixels): Moved Image pixel methods to
        Pixels class.

2000-02-29  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (annotate): Re-wrote to improve performance.
        (draw): Re-wrote to improve performance.

2000-02-26  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Drawable.cpp (text): Bugfix: support spaces in annotation text.

2000-02-23  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (floodFillTexture): Fixed bug due to pixel pointer
        becoming invalid in ImageMagick function.

2000-01-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (floodFillTexture): Changed coordinates to unsigned.

1999-12-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (medianFilter): New method.

1999-12-18  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (density): Bug fix. Was not setting image x & y density.

1999-11-30  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (page): psPageSize() is renamed to page() and now
        properly returns the attribute from the image.

1999-11-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp: Rename transformColorSpace() to colorSpace().
        Added colorSpace() accessor method.

1999-11-24  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (quantizeError): Eliminated method.

1999-11-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (annotate & draw): Changed implementation to
        reflect change to the way AnnotateInfo is managed by ImageMagick.

1999-11-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Blob.cpp (BlobRef): Bugfix -- start blob reference count at
        one rather than zero.

1999-10-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Image.cpp (condensed): Bug fix.  The condensed() method was returning the opposite bool value than it should.  Oops!

1999-09-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/Magick++/Include.h (MagickCore): Eliminated requirement for
        including <magick/define.h>.

1999-08-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/MagickImage.cpp (composite): Support composition placement
        by gravity like PerlMagick does.

1999-07-07  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/MagickImage.cpp (Image): Added constructors to construct an
        Image from a BLOB.

1999-07-06  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * tests/manipulate.cpp (main): Wrote a basic sanity test for
        reading and writing BLOBS.

1999-06-21  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/MagickInclude.h : Use new <magick/api.h> 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/MagickBlob.cpp (Blob): Support default constructor for Blob.

1999-05-16  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * lib/Makefile.am (libMagick): Updated to use libtool 1.3 so that
        shared library can be built.

1999-04-25  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * lib/MagickImage.cpp (montageGeometry): Return Magick::Geometry
        rather than std::string.

1999-04-19  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * 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  <bfriesen@simple.dallas.tx.us>

        * demo/flip.cpp (main): New file.  Demonstrates use of flipImage
        function object as well as morphImages algorithm.

1999-04-10  Bob Friesenhahn  <bfriesen@simple.dallas.tx.us>

        * 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.
