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.

XJT Fileformat specification:
------------------------------
(XJT 1.1, 1998.10.31 - 1999.03.16)
----------------------------------------------------------------
XJT Fileformat was designed to save compressed GIMP Images with
all the properties that are available in GIMP.
XJT uses JPEG compression foreach layer or channel and TAR to
collect all layers in one file. (Layers with alphachannels
are splitted into 2 jpeg files)
Additional property informations about offsets, opacity, layernames etc..
are stored in the readable textfile called "PRP" (Properties)
The resulting tar-file is optionaly compressed a 2.nd time
using GZIP or BZIP2.
(depends on the filename ending "gz" or "bz2")
Filename Extensions are:
image.xjt # plain tar file
image.xjtgz # gzip compressed tar file
image.xjbz2 # bzip2 compressed tar file
Restrictions:
-------------
** XJT does not support INDEXED Images. **
Why should anyone use the new XJT Fileformat ?
---------------------------------------------
XJT Advantages:
- The high JPEG compression rates (1:10 and more) helps
to save a lot of Diskspace.
(especially if you are using GIMP and GAP to
store many images as AnimFrames )
- Saved image keeps all layers channels and properties
- single Layers can be extracted using tar
and then be accessed by many other
jpeg-compatible programs.
XJT Disadvantages:
- JPEG is a lossy compression.
After save and load the bitmapdata
differs a little from the original,
depending on the used quality setting.
==> use GIMP's native xcf format
where you need exactly the original.

The example image has dimensions of 256x256 pixels.
The Image Type is RGB (default Property typ:0)
L0 The Image has a floating selection (stored as l0.jpg) at offset 35/116.
The floating selection has an alpha channel (stored in la0.jpg)
The floating selection is the active Layer.
There are 2 further Layers.
L1 at offset 077 is named "Pasted Layer" and is stored in l1.jpg.
This Layer has both an alpha channel (stored in la1.jpg)
and a LayerMask (stored in lm1.jpg)
(the Properties of the LayerMask are stored in an extra Line
of the PRP file beginning with m1)
l2 is the Background Layer without alpha channel. (stored in l2.jpg)
The Floating selection is attached to this layer ("fa" Property)
c0 The image has one extra channel named "saved selection mask"
This channel has full red color (c:255,0,0 property) and an opacity
value of 33.725 % but is invisible ("iv" property)

changelog:
------------------------------------------------
- XJT Version 1.1
XJT Format 1.1 was extended for
RESOLUTION, TATTOO's, and PARASITES
Please note that TATTOO's and PARASITES are only defined
but not implemented.
(Gimp 1.1.3 has no PDB-Interfaces to enable Plug-Ins
to Load/Save TATTOO's and PARASITES)
PARASITES: The parasite data is stored in a seperate file for each
parasite. The file is named p<id>.pte, where
<id> is a unique integer parasite Id.
A Layer, Channel or Image can have 0 or more PROP_PARASITE
Properties (pte:1 pte:2 ...), where the integer parameter
refers to the unique parasite id.
Parasite entries can have a Name Property.
