ImageMagick Studio LLC announces the release of ImageMagick 6.4.1-8.
Introduction to ImageMagick
ImageMagick® is a software suite to create, edit, and compose bitmap
images. It can read, convert and write images in a
... [More]
variety of formats
(over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG,
Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror,
rotate, scale, shear and transform images, adjust image colors, apply various
special effects, or draw text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command
line or you can use the features from programs written in your favorite
programming language. Choose from these interfaces: G2F (Ada), MagickCore
(C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM ), Magick
(C ), JMagick (Java), L-Magick (Lisp), NMagick (Neko/haXe), MagickNet
(.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP
(PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick
(Tcl/TK). With a language interface, use ImageMagick to modify or create
images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution
or as source code that you may freely use, copy, modify, and distribute. Its
license is compatible with the GPL. It runs on all major operating systems.
Features and Capabilities
Here are just a few examples of what ImageMagick can do:
* Format conversion: convert an image from one format to another (e.g.
PNG to JPEG)
* Transform: resize, rotate, crop, flip or trim an image
* Transparency: render portions of an image invisible
* Draw: add shapes or text to an image
* Decorate: add a border or frame to an image
* Special effects: blur, sharpen, threshold, or tint an image
* Animation: create a GIF animation sequence from a group of images
* Text & comments: insert descriptive or artistic text in an image
* Image identification: describe the format and properties of an image
* Composite: overlap one image over another
* Montage: juxtapose image thumbnails on an image canvas
* Motion picture support: read and write the common image formats used in
digital film work
* Image calculator: apply a mathematical expression to an image or image
channels
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows
* Large image support: read, process, or write mega- and giga-pixel image
sizes
* Encipher or decipher an image: convert ordinary images into
unintelligible gibberish and back again
* Threads of execution support: ImageMagick is thread safe and many
internal algorithms are already threaded to take advantage of speed-ups
offered by the dual and quad-core processor technologies
See http://www.imagemagick.org for more details.
Examples of ImageMagick Usage shows how to use ImageMagick from the
command-line to accomplish any of these tasks and much more. See
http://www.imagemagick.org/Usage/.

To handle an invalid, zero-length vpAg chunk properly will require
libpng-1.2.27 or later.
2008-04-04 6.4.0-5 Cristy < at >image...>

tile size is specified (e.g. ptif:image.tif[128x128]).
* Malformed use of caption no longer consumes memory (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=10914).

* Special effects: blur, sharpen, threshold, or tint an image
* Animation: create a GIF animation sequence from a group of images
* Text & comments: insert descriptive or artistic text in an image
* Image identification: describe the format and properties of an image
* Composite: overlap one image over another
* Montage: juxtapose image thumbnails on an image canvas
* Motion picture support: read and write the common image formats used in
digital film work
* Image calculator: apply a mathematical expression to an image or image
channels
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows.
* Large image support: read, process, or write mega- and giga-pixel image
sizes
* Threads of execution support: ImageMagick is thread safe and many
internal algorithms are already threaded to take advantage of speed-ups
offered by the dual and quad-core processor technologies.
Examples of ImageMagick Usage (http://www.imagemagick.org/Usage) shows how
to use ImageMagick from the command-line to accomplish any of these tasks
and much more.
See http://www.imagemagick.org for more information about ImageMagick.
Significant changes since the last official ImageMagick release, include:
2007-09-29 6.3.6-0 Anthony < at >griffith...>
* Added Scaling 'derivitives' to -distort Arc, so image arcing is now
sharp and clear as you approach the center of the distort.
* Added " -set option:distort:viewport 'geometry' " special option
that can be used to override the output image size and offset.
* Fixed experimental use of -filter and -support in Resampling (more later).
* Changed order for coordinate arguments in -distort (for leastsq addition)
2007-09-22 6.3.6-0 Cristy < at >image...>
* Check the API version and quantum depth before loading a coder module or
image filter (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9780).
* Add exception to the image filter signature.
* Get the execution path under Mac OS X.
* TIFFTAG_STRIPBYTECOUNTS requires a uint32 pointer (magick/compress.c).
* Fixed memory leak in CloneString() (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=9763).
* Set S_IRUSR | S_IWUSR | S_IRGRP mode when writing a file in
CopyDelegateFile(). [Less]
