New in ImageMagick 6.5.9 (Feb 2, 2010)

  • Make -define png:color-type less persnickity about what it will accept.
  • added use of -precision in 'showkernel' output of -morphology
  • correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and 'Distance' Morphology primatives. This does not have a performance hit, though is only truely applicable when the kernel is asymmetric. Note that 'Erode' does not use a 'reflected' kernel, so that 'Open' and 'Close' operations work properly. This 'reflected usage is defined by online morphology lecture notes (Google for "EECE Binary Morphology")
  • Added convolve kernel scaling setting "-set option:convolve:scale N" If undefined morphology convolve does not do any scaling or normalization of the convolution kernel. A value of 0.0 causes normalization for both zero and non-zero (added weights) kernel types.
  • Speed up reading the PSD image format.
  • Add the -precision option. Use it to set the maximum number of significant digits to be printed.
  • Add -features option to the identify program to display channel features.

  • Transparent images no longer flicker on certain system when using the display program.
  • Permit interactive resizing with the display program.
  • Support heterogeneous distributed processing, see http://www.imagemagick.org/script/architecture.php#distributed.
  • Fix semaphore assertion when reading a corrupt image with Magick++.
  • Add support for -brightness-contrast option.
  • Add support for the BGRA raw image format.
  • Added Kernel Generator to generate kernels from user strings, which allows the generation in many built in kernels for both Convolution and other Morphological methods. New Kernels currently include.. Convolution: Gaussian, Blur, Comet Morphological: Rectangle, Square, Diamond, Disk, Plus Distance: Chebyshev, Manhatten, Knight, Euclidean And both old and new (rectangular) user defined kernel specifications including the use of 'nan' to represent elements which are not part of the kernel definition. List built-in kernel types use "-list kernel"
  • Added -morphology {method}[:{iteration}] {kernel_string} Initial methods includes no only the basic morphology methods: Dilate, Erode, Open, Close; and a pixel color preserving 'Intensity' version, but also the special methods: Convolve, and Distance. Of course the appropriate kernel should be provided for each specific method.
  • Add OpenCL-enabled filter (e.g. convert image.png -process "convolve '-1, -1, -1, -1, 9, -1, -1, -1, -1'" image.jpg).
  • Added StringTo...() processing functions

New in ImageMagick 6.3.9 (Mar 10, 2008)
