A new version of the GIMP has been released. 0.54 features some
improvements over earlier versions and many bug fixes. (I tried my
hand at using Purify and found out what an extremely cool tool it
is). Also available are precompiled binaries for HP's, Suns (both
Sunos 4.1.x and Solaris), SGI's, and Linux a.out. I'm attaching the
README file to the end of this message which contains the url's for
getting the source and binaries.

This is a partial list of changes from earlier versions:

* Fixed lots of other shit...added targa (tga) and pnm support...
* Fixed a bit of stupid programming that caused some memory in
autodialogs to never be freed.
* Windows tend to retain their scale when using plug-ins which
create new images now. (Such as "duplicate").
* Used purify and found some stupid memory bugs. These include
creating several arrays 1 byte too small and using unitialized memory
in one instance.
* Fixed a bug in bezier selections when an anchor point was outside
of the image.
* Implemented a dirty bit for images. Modified images will prompt to
be saved before being closed.
* Made a slight modification to the way the file overwrite dialog works.

Future plans
- ------------

During Christmas break we encountered Photoshop 3.0 and discovered the
"joy of layers". This functionality was deemed absolutely necessary
and will part of the next release of the GIMP. This will involve major
changes to many parts of the GIMP and is not expected to be ready for
several months. The other major item being changed is a reworking of
the interface (and perhaps the dropping of Motif!). Please do not bug
us about when these changes will be ready. It only distracts us and
slows us down. (Suffice it to say, we think the changes will be worth
the wait).

The GIMP: the General Image Manipulation Program
- ------------------------------------------------

The GIMP is designed to provide an intuitive graphical interface to a
variety of image editing operations. Here is a list of the GIMP's
major features:

Image viewing

* Supports 8, 15, 16 and 24 bit color.
* Ordered and Floyd-Steinberg dithering for 8 bit displays.
* View images as rgb color, grayscale or indexed color.
* Simultaneously edit multiple images.
* Zoom and pan in real-time.
* GIF, JPEG, PNG, TIFF and XPM support.

Image editing

* Selection tools including rectangle, ellipse, free, fuzzy, bezier
and intelligent.
* Transformation tools including rotate, scale, shear and flip.
* Painting tools including bucket, brush, airbrush, clone, convolve,
blend and text.
* Effects filters (such as blur, edge detect).
* Channel & color operations (such as add, composite, decompose).
* Plug-ins which allow for the easy addition of new file formats and
new effect filters.
* Multiple undo/redo.

- ------------

* The operating system must support shared memory.
* X11 R5 or R6. (Actually, it may work on R4, but we have not had a
chance to test it).
* The X-server must support the X shared memory extension. (The
X-server does not actually need to support shared memory so this is
only a temporary situation until we integrate the configure
information with the source code).
* Motif 1.2 or above.

The GIMP has been tested (and developed) on the following operating
systems: Linux 1.2.13, Solaris 2.4, HPUX 9.05, SGI IRIX.

Currently, the biggest restriction to running the GIMP is the Motif
requirement. We will release a statically linked binary for several
systems soon (including Linux).

This software is currently a beta release. This means that we haven't
implemented all of the features we think are required for a full,
unqualified release. There are undoubtedly bugs we haven't found yet
just waiting to surface given the right conditions. If you run across
one of these, please send mail to with
precise details on how it can be reproduced.

Version: 2.6.2i
