xjt is a file plug-in to load and save GIMP RGB and GRAY Images with
all its layers, channels and guides.
Started implementation TATTOO, PARASITE RESOLUTION 1999.02.01
(see README_xjt_fileformat.txt for more Information about XJT)
The XJT Load/Save Plugin requires:
- GIMP 1.0.0 (or better)
- libjpeg
- Unix tar
- Unix gzip (optional)
- Unix bzip2 (optional)
- gap_patches (optional) **)
**) NO PATCHES are required if you have the latest development version of GIMP 1.1
Installation:
-------------
If You are using GIMP 1.0.2 (or older versions):
# (optional) install gap_patches
# they are available at the registry at:
# http://gimp.foebud.org/registry/detailview.phtml?plugin=gap_patches
# or at:
# http://gimp.foebud.org/registry/detailview.phtml?plugin=gap
cp Makefile.1.0 Makefile
If you are using GIMP 1.1.1
# GIMP 1.1.1 is an unstable prerelease.
cp Makefile.1.1 Makefile
# edit the Makefile to fit your setup
# then type
make # to compile and
make install # to install the plugin
Change Log:
-----------
1.02 1999.02.?? added load/save for resolution, tattoos, and parasites
(works only with gimp 1.1.1)
1.01 1998.11.24 added load/save for guides (works only with gimp 1.1)
added Makefiles to compile xjt under gimp 1.0.2 and 1.1
Restrictions of the XJT release 1.01:
-----------------------------------------
The 1.01 implementation of xjt is now able to save and load
the full Image Information (including guides) on RGB and GRAY Images.
when xjt is used with the latest development version of GIMP 1.1.
If xjt is used with GIMP 1.0.2 (or earlier versions)
there are some restrictions:
GUIDES are ignored at save and load.
(GIMP 1.0.2 has no Interface to access GUIDES from a plugin)
LINKED to load/save the linked state of a Layer
you must install the GAP_PATCHES to the gimp core.
(GIMP 1.0.2 has no Interface to access the Layers LINKED state from a plugin)
FLOATING_SELECTION
are supported by the XJT Fileformat, but you need to apply the GAP_PATCHES
to the gimp core.
Without the patches:
- XJT can not find out the drawable where the floating selection
is attached to. (the PROP_FLOATING_ATTACHED property information
is not saved to the PRP file in that case)
- XJT can not attach the floating selection to a layer or channel
at load. (even if you add the PROP_FLOATING_ATTACHED to the PRP file
with an editor)
The GAP_PATCHES provide some of the missing PDB-interfaces
(except those for guides, tattoos, parasites and resolution)
for GIMP-core versions from 1.0.0 upto 1.0.2.
