You can reduce the colour +depth by setting indexed mode in the GIMP (image - mode). It may be +sensible to use only 14 or 15 colours (to leave something for the +text?) - but I didn't really investigate this further. I reduced +my image to 14 colours. +Then you can export it to a .ppm file, which serves as input to the +perl script ppmtolss16, (which comes from the syslinux tarball - +its inverse is lss16toppm, which is also in there): + +./ppmtolss16 < splash.ppm > splash.lss + +To test this, convert it back and take a look at the result: + +./lss16toppm < splash.lss > test.ppm + +Just replace the existing splash.lss file (in cd-root/isolinux) with your +version. |
