This file records noteworthy changes in Magick++. As of Magick++ 5.2.3, Magick++ release numbering tracks ImageMagick release numbering so the Magick++ release number increments even if there are no changes associated with Magick++ itself.

(5.4.6)

• Magick++ library no longer depends on C++ iostreams APIs.
• Added DrawableTextUnderColor class to set text underbox color.

(5.4.5)

• Drawable classes have been re-written to use ImageMagick's draw.h APIs.
  
• Fixed a nasty bug when reporting some forms of errors. The bug was causing an exception in error.c.
• Template API implementation cleanup.
• Rationalized some parameter types.
• New method, Pixels::getConst() to obtain read-only pixels.
• DrawableDashArray() prefers an array of type 'double' rather than 'unsigned int'. Please use the new form.

• Blob class supports encoding and decoding Base64 data.
• New method, Image::ping to ping a Blob.

(5.4.4)

• Fixed a bug in DrawableDashArray.
• Numerous consistency improvements based on findings from Gimpel lint.
• Added endian method to Image, and endianImage class to STL.h in order to support setting endian option for formats which support the notion (e.g. TIFF).
  
• DrawableCompositeImage was not working. Now it does.

(5.4.3)

• Support selecting fonts via font-family, font-style, font-weight, and font-stretch via the DrawableFont class.

• Bugfix for Magick::Exception memory leak.

• Added the medianFilter() method to Image.
• Renamed transformColorSpace() to colorSpace() and added a colorSpace() accessor method.
  
• Renamed psPageSize() to page(), which now properly returns the actual attribute from the image, rather than the image options. This is important in order to manipulate GIF animations.
• Bug fixes.

(0.9)

• Ported to ImageMagick 5.0.
• BLOB sizes are now specified using size_t type.
• Rotate() no longer accepts sharpen or crop options.
• Shear() No longer accepts a crop option.

(0.8.9)

• Released with ImageMagick 4.2.9

(0.8.8)

• Fixed a Image constructor bug when constructing from a Blob

(0.8.7)

• Bugfix: condensed() was returning wrong state.

(0.8.6)

• Color is now based on ImageMagick's RunlengthPacket structure (via a pointer) so that it may eventually be used to represent an image pixel. This is currently a work in progress.

(0.8.5)

• Headers are now installed under prefix/include/Magick++ on Unix systems with the exception that Magick++.h is installed under prefix/include as it was before. Programs which include Magick++.h (the documented approach) should not be impacted.
• Image constructors to construct an image from a BLOB.
• Image read and write methods to decode and encode images stored in a BLOB. This allows reading/writing image "files" from/to memory rather than a traditional file.

(0.8.4)

• New mapImages algorithm maps a sequence of images to the colormap of a provided image.
  
• New quantizeImages algorithm computes and applies a common colormap to a sequence of images.

(0.8.3)

• Blob supports default constructor.
• New Blob method updateNoCopy() to support efficient initialization by derived class.

(0.8.2)

• Uses libtool 1.3 to build library under Unix and Cygwin (static lib only).
• Added Blob class to support supplying formatted binary data to methods.
• Added support for setting ICC and IPTC profiles from a binary BLOB.
• Added support for transformations of image data to/from alternate colorspace (e.g. CYMK).
  
• Added support for 'pinging' an image (get image dimensions/size quickly).
• Added 'uncondense' method to de-compress in-memory image data.
• Added support for annotation using rotated text.

(0.8.1)

• Added support for setting alpha in Magick::Color
• Set/get color alpha in Magick::Image::pixelColor() for DirectClass images.

(0.8)

• Transitioned to Beta
• Improved Microsoft Visual C++ build environment.

(0.7.4)

• Added animateImages() and displayImages() to MagickSTL.h.
• Added function objects to support setting image attributes.

(0.7.3)

• Image::penTexture() now takes Image reference rather than Image pointer. Set Image to invalid using isValid(false) to unset texture.
  
• Attribute methods that take Color, Geometry, Image, or string arguments may now unset the attribute by setting the state of the object to invalid using isValid(false), or the empty string (in the case of string). This allows full control over ImageMagick attributes which are stored as C strings which may be set to NULL.
• Updated for ImageMagick 4.2.1

(0.7.2)

• Added STL function object support for all Image manipulation methods to support operating on all or part of the images stored in an STL container.

(0.7.1)

(0.1)

• All ImageMagick operations which operate on individual images are supported.
  
• Image objects have value semantics, avoid unnecessary image copies through the use of reference counting, and may be compared via standard operators.
  
• Geometry, color, annotations, and user-options are supported by separate classes.
  
• Errors are reported synchronously via C++ exceptions.
