Significant changes associated with GraphicsMagick 1.1.11 (released September 23, 2007)
Bugs Fixed:
o BMP: Support large files.
o DIB: Support large files.
o PNG: Fix depth handling with 16-bit PNG files in the Q8 build.
o SUN: Properly report image depth.
o TIFF: Endian option (-endian) now controls TIFF byte endian order
rather than bit fill order.
o DCM, DIB, XBM, XCF, XWD: Eliminate integer overflow vulnerability
(IDefense 09.19.07).
o HSL colorspace transform: Avoid optimization bug noticed on Opteron
with GCC.
o HWB colorspace transform: Avoid optimization bug noticed on Opteron
with GCC.
o RGBTransformImage()/TransformRGBImage(): Was using HWB colorspace
when HSL was requested.
o Successfully reads files with names like 'file[123]'.
o 'gm display': No longer rely on isatty() to determine if input is
from a pipe (use 'gm display -' to display an image read from a pipe).
Feature Improvements:
o 'identify +ping' forces the pixels to be read (similar to GM 1.2).
o 'gm -version' now indicates if build supports "Large Memory" (i.e. 64-bit).
o TIFF: Use '-define tiff:fill-order={msb2lsb|lsb2msb}' to control
TIFF bit fill order.
Performance Improvements:
o No longer bogs down if a directory contains hundreds of thousands of
files and the filename looks like a wildcard specification.

Significant changes associated with GraphicsMagick 1.1.10 (released September 19
, 2007)
Bugs Fixed:
o Image rotate by -90/270 degrees was producing wrong output.
Significant changes associated with GraphicsMagick 1.1.9 (released September 16, 2007)
Bugs Fixed:
o In mogrify command, don't remove file name based on random junk in
memory.
o Fixed memory leak when reading MPC files.
o Fixed crash when writing MIFF format and depth is not expected 8/16/32/.
o Find latest Ghostscript under Windows which identifies itself as
"GPL Ghostscript".
o In mogrify command, don't leak memory in the case where the image
file contains multiple frames.
o Fixed crash in PNG and JPEG coders when the image to be written is
part of an image list.
o PNG reader errors are now properly reported to the user.
o TIFF output can now be written to a pipe or other non-seekable
destination.
o Support writing PDF with CCITT compression.
Feature Improvements
o Added a new 'benchmark' command which can be used to perform
benchmarking on any other command.
o Image rotate in clockwise (90 degrees) or counter-clockwise (270
degrees) direction is now 2-9X faster than before.
o The -version option now includes a list of supported features.
o For Windows MinGW-based build, find Ghostscript fonts installed
under C:/Program Files/.

GraphicsMagick(TM) provides a powerful image manipulation and
translation utility. It is capable of displaying still images and
animations using the X Window system, provides a simple interface for
interactively editing images, and is capable of importing selected
windows or the entire desktop. GraphicsMagick can read and write over
88 image formats, including JPEG, TIFF, WMF, SVG, PNG, PNM, GIF, and
Photo CD. It can resize, rotate, sharpen, color reduce, or add
special effects to the image and save the result to any supported
format. GraphicsMagick may be used to create animated or transparent
.gifs, create composite images, create thumbnail images, and much,
much, more.
GraphicsMagick is one of your choices if you need a program to
manipulate and display images. If you want to develop your own
applications which use GraphicsMagick code or APIs, you need to
install GraphicsMagick-devel as well.
