The tools +are designed to allow efficient use of layered XCF files as +sources in a build system that use 'make' and similar tools +to manage automatic processing of the graphics. These tools +work independently of the Gimp engine and do not require the +Gimp to even be installed. + + xcf2pnm converts XCF files to ppm, pgm or pbm format, + flattening layers if necessary. If the image + contains transparency, an alpha map can be written + to a separate file, or a background color can be + specified on the command line. + + xcf2png converts XCF files to PNG format, flattening + layers if necessary. Transparency information + can be kept in the image, or a background color + can be specified on the command line. + + xcfinfo lists information about layers in an XCF file. + +The tools can either flatten an XCF file as given, or extract specific +layers named on the command line. + +Portability +=========== + +The software was developed on an Intel-based pc running Debian +GNU/Linux. It ought to work on other Linux variants also. I would +not be surprised if it ran on other unix systems too, but porting +to non-unix platforms will require some work. Most of the code +attempts to be prepared for porting, but this has not been +explicitly tested. + +Installation +============ + +You need GNU make, a C compiler, and perl. + +After the source archive is extracted, the command sequence + ./configure + make all + make install +should compile the tools and install them in /usr/local. + +The 'configure' script is generated by GNU autoconf, and accepts +the arguments that such scripts commonly do. + +License +======= + +Xcftools is written by Henning Makholm <henning@makholm.net> +(Copyright 2006). + +Xcftools is free software; you can redistribute it and/or modify +it under the terms of version 2 of the GNU General Public License as +published by the Free Software Foundation. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
