  • Added the medianFilter() method to Image.
  • Renamed transformColorSpace() to colorSpace() and added a colorSpace() accessor method.

  • BLOB sizes are now specified using size_t type.
  • Rotate() no longer accepts sharpen or crop options.

(0.8.9)

  • Released with ImageMagick 4.2.9

  • Fixed a Image constructor bug when constructing from a Blob

(0.8.7)

  • Bugfix: condensed() was returning wrong state.

(0.8.6)

(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.

  • 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)

  • 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 '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.

  • User options are now completely contained within Image object. There is no longer a MagickOptions parameter to some methods.

(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.
