ImageMagick Studio LLC announces the release of ImageMagick
6.2.6.
ImageMagick®, version 6.2.6, is a free software suite to
create, edit,
and compose bitmap images. It can read, convert and write
images in a
large variety of formats. Images can be cropped, colors can
be changed,
various effects can be applied, images can be rotated and
combined,
and text, lines, polygons, ellipses and Bézier curves can
be added to
images and stretched and rotated.
ImageMagick is free software: it is delivered with full
source code and
can be freely used, copied, modified and distributed. Its
license is
compatible with the GPL. It runs on all major operating
systems.
Most of the functionality of ImageMagick can be used
interactively
from the command line; more often, however, the features are
used
from programs written in the programming languages C, Ch,
C++, Java,
Lisp, Pascal, Perl, PHP, Python, Ruby, Tcl/Tk, for which
ready-made
ImageMagick interfaces (MagickCore, MagickWand, PerlMagick,
Magick++,
PythonMagick, MagickWand for PHP, RMagick, TclMagick,
L_Magick, and
JMagick) are available. This makes it possible to modify or
create images
automatically and dynamically.
ImageMagick supports many image formats (over 90) including
formats like
GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX.
Here are just a few examples of what ImageMagick can do:
* Convert an image from one format to another (e.g. PNG
to JPEG)
* Resize, rotate, sharpen, color reduce, or add special
effects to
an image
* Create a montage of image thumbnails
* Create a transparent image suitable for use on the Web
* Turn a group of images into a GIF animation sequence
* Create a composite image by combining several separate
image
* Draw shapes or text on an image
* Decorate an image with a border or frame
* Describe the format and characteristics of an image
Examples of ImageMagick Usage:
h
ttp://www.cit.gu.edu.au/~anthony/graphics/imagick6
shows how to use ImageMagick to accomplish any of these
tasks and much
more or see the ImageMagick home page at
http://www.imagemagick.org
ImageMagick Studio recommends upgrading due to this
important security fix:
* Prevent shell command injection in delegate code (via
file names), See
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=345238.
Significant changes since the last official ImageMagick
release, include:
2006-03-30 6.2.6-7 Anthony Thyssen <anthony griff...>
* Added the 'Dispose' layers function to return the
'GIF dispose' images of
an animation.
2006-03-30 6.2.6-7 Cristy <nagualimage...>
* File is already closed, do not call fclose() on it in
magick/blob.c.
* PS3/EPS3 now writes a proper image mask when compression
is None.
* Patch to properly read interlaced GIF's.
* DestroyMagick() is not always reliably available when
atexit() unwinds.
2006-03-26 6.2.6-6 Cristy <stentzimage...>
* Specify '-depth 32 -define
quantum:format=floating-point' to read/write
single precision floating point TIFF and raw formats.
* Specify '-depth 64 -define
quantum:format=floating-point' to read/write
double precision floating point TIFF and raw formats.
* If you overlaying an image with a negative offset, the
image is no
longer wrapped around the left and right edges of the
canvas.
2006-03-20 6.2.6-5 Cristy <stentzimage...>
* Fix Group4-compression in the PDF writer.
2006-03-06 6.2.6-4 Cristy <stentzimage...>

display -- -logo.png).
* Do not set the image opacity when reading a PSD colormap
index (reference
http://redux.imagemagick.org/discussion-serv
er/viewtopic.php?p=18026).
* By default, ImageMagick sets the page size to the
MediaBox. Some
PDF files, however, have a CropBox that is smaller than
the MediaBox and
may include white space, registration or cutting marks
outside the CropBox.
To force ImageMagick to use the CropBox rather than the
MediaBox, use
-define (e.g. -define pdf:use-cropbox=true).
* RGB to CMYK color conversion is now scaled properly.
2006-03-01 6.2.6-3 Cristy <stentzimage...>
* The command line utilities properly returns a non-zero
status when an
exception is thrown.

injection for the
any command line delegates (initial patch from Daniel
Kobras).
* Some PSD CMYK images were not read properly.
2006-01-13 Cristy <stentzimage...>
* Conform to W3C CSS3 Color Module recommendation for
specifying colors.
We now include hsl() and hsla() (e.g. hsl(120, 50%, 50%)
for pastel green).

be done. It
currently behaves just like CompositeImage().
2006-01-06 Cristy <stentzimage...>

option (suggested by
Anthony).
* Move *ImageCommand() calls from MagickCore to
MagickWand.
2005-12-01 Cristy <stentzimage...>

display window
rather than the temporary filename (e.g. image.miff.gz
rather than
/var/tmp/magick-XXa18945).

second.
* Clone the virtual pixel method when cloning the image
cache (thanks to
Anthony for discovering this bug).
* 'montage rose: -geometry 0 rose.gif' no longer seg
faults (bug report by
Anthony).
* Compute correct image statistics for grayscale images.
* Given -crop WxH+X+Y! the image page width and height is
set to WxH and
the image offset has the crop offset subtracted, so the
image is relative
to the new crop/page/canvas area.
2005-09-03 Cristy <stentzimage...>

special effects.
2005-08-06 Cristy <stentzimage...>
* resizing a light colored image on a transparent
background will now NOT
produce a incorrect black halo.
* The experimental -identify option has been replaced
with info:. This
special output format will do the same task as the
'identify' command,
but will allow you to save the result into a seperate
file or to
standard output. This output format will understand the
use of the
-format setting within the convert command.
* -label and -draw text will no longer deal with the
special escapes chars.
That is percent '%' image info formats will nolonger
be expanded, or
'\n' newlines (for multiple line draws) handled.
* A new -extent operator. This is a ultra-fast and
simple image size
changer. The image data is preserved in the topleft
corner of the
resulting image, but no effort is made to set any form
of background
color, or preserve image data that falls outside the new
image size.
Note -crop is still the preferred operator, but this is
appropriate for
handling very very large, or huge numbers of images.
