This is my second release of Gimp for AmiCygnix.

GIMP is an acronym for GNU Image Manipulation Program. It is a freely distribu-
ted program for such tasks as photo retouching, image composition and image
authoring.

It has many capabilities. It can be used as a simple paint program, an expert
quality photo retouching program, an image format converter, etc.

GIMP is expandable and extensible. It is designed to be augmented with plug-ins
and extensions to do just about anything.


New in this release
-------------------

  * New version 2.4.7

  * Plug-ins are working now. Other file formats, filter effects etc. are
    possible now.

  * Compiled in modules for color selection and display filters.


Loaders and savers
------------------

  This version of Gimp contains several internal loader and saver formats.
  Because of this, you can load and save foreign picture formats, even if the
  external loader plug-ins are missing.

  The original loader plug-ins will be available in a separate package, because
  the amount of data is too high. At the moment all programs are linked stati-
  cally on AmiCygnix. Many plug-ins do have a filesize of 11 - 12 MB because of
  this.

  Internal loaders:

    - XCF
    - BMP
    - GIF
    - ICO (Windows-Icon)
    - IFF-ILBM
    - JPEG
    - PCX
    - PNG
    - PNM
    - RAS
    - TGA
    - TIFF
    - WBMP
    - XBM
    - XPM

  Internal savers:

    - XCF
    - BMP
    - JPEG
    - PNG
    - TIFF

  The advantage of the internal loaders is the higher speed compared to the
  external plug-ins. On the other hand the external plug-ins do have more
features
  and more file formats are available.


Included plug-ins
-----------------

  Important:

  To reduce the size of this package, only some selected plug-ins are included.
  Additional plug-ins will be available in separate packages.
  At the moment all programs are linked statically on AmiCygnix. Many plug-ins
  do have a filesize of 11 - 12 MB because of this.

  All installed plug-ins are stored in the directory "Cygnix:CygnixPPC/lib/gimp/
  2.0/plug-ins".

Compiled in modules
-------------------

     * colorsel_water

  b) Display modules

     These modules are buggy at the moment. If you use them the second time,
     Gimp will be cancelled! They are deactivated by default because of this.

     Use them at your own risc!

     * cdisplay_colorblind

Problems
--------

  * Changes in the module preferences are only regognized after a relaunch of
    Gimp.

  * Plug-in windows will not be closed automatically, when you quit Gimp. Please
    close them by hand.
