Magick++ ChangeLog

2008-03-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Geometry.cpp, lib/Image.cpp: Include <strings.h> since it is needed in order to use strcpy().

2007-07-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp: Include <cstdlib>

2006-10-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (pixelColor): Don't enforce color "validity" when setting the pixel color.

2004-06-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Magick++/Include.h: Disable unavoidable warnings under Visual C++ when instantiating STL templates within DLL code. Consensus from postings on the net is that as long as the same C++ compiler is used throughout, these warnings are of no concern.

2004-05-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Magick++/STL.h (coderInfoList): Make error reporting a bit more lenient so that if an error occurs while loading a module it is not reported as an exception unless no coders were found at all.

2004-04-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/CoderInfo.cpp (CoderInfo): Sense of isReadable() and isWritable() was inverted.

2004-04-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Magick++/Include.h: <inttypes.h> is not used. Inclusion removed.

2004-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Thread.cpp (lock): Have not been successful with using MsgWaitForMultipleObjects() reliably, so back out usage of it for now.

2004-03-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Thread.cpp (lock): For MsgWaitForMultipleObjects, monitor state change only. Otherwise lock may deadlock.

2004-03-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (statistics): New method to obtain image statistics (minimum, maximum, mean, variance, and standard deviation).

2004-03-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (quantumOperator): New image method to apply an arithmetic or bitwise operator to the pixel quantums in an image. Still needs documentation.

- lib/Image.cpp (compose): Added a method to set/get the Image composition option.

2004-03-06 Vladimir Lukianov <lvm@integrum.ru>

- lib/Thread.cpp (lock): Use MsgWaitForMultipleObjects() rather than WaitForSingleObject() in order to avoid possible deadlock when application code directly or indirectly creates windows.

2004-02-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (interlaceType): Retrieve interlace setting from Image rather than ImageInfo.

2004-02-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (Image): Delete the allocated image reference object if a Magick::Error is thrown by the Image constructor. Otherwise the image reference object becomes a memory leak.

2004-01-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Magick++/STL.h (WriteImages): Pass Blob::MallocAllocator to updateNoCopy() in order to ensure that correct deallocator is used.
- tests/readWriteBlob.cpp (main): Needed to delete character array using array [] reference.

2004-01-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- demo/analyze.cpp (main): Fix a GNU C++ library portability problem noticed under MinGW. The 'left' iostream manipulator seems to be missing.

2004-01-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- tests/Makefile.am: coderInfo test is expected to fail for moby builds when the package is not yet installed since a .la file exists in the coders directory, but there is no associated .so file. Therefore failures of the coderInfo test are now ignored.

2003-12-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (defineValue): New method to support setting format-specific defines.
  (defineSet): New method to support setting or testing for format-specific flags.

2003-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- lib/Image.cpp (iccColorProfile): Implementation now uses the profile method with profile name "ICM". Note that this now invokes the color profile if the image already has one. (iccColorProfile): Reimplement using new GetImageProfile function. (iptcProfile): Reimplement using the new GetImageProfile and SetImageProfile functions.
  (profile): Reimplement using new GetImageProfile function.

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

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 GraphicsMagick 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.

2003-05-16 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 (MagickLib::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 (GraphicsMagick 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 GraphicsMagick++.pc.
- lib/GraphicsMagick++.pc.in : Added pkgconfig file for -lGraphicsMagick++.

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>.

2002-11-08 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.

2002-04-19 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>

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(MagickLib::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>

2001-11-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

- 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 <bfriesen@sun1107.ssd.usa.alcatel.com>

- lib/Image.cpp (strokeDashArray): Change to type double. (strokeDashOffset): Change to type double.

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

2000-10-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

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

- 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.

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>

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.

2000-04-16 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.

- 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.

- 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>

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.

- 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 MagickLib::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 to a MagickLib::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.
