did you have a way for convert an image into 30 color mode but with 8*8 tiles use only one palette? Because with this way the palette are mixed into one tiles. I made a Perl script that does that.

Finally I made a Perl script that uses ImageMagick and that generates something that the MD can actually display. The script is here: http://edis.zapto.org/md/bitmap2md.pl It needs two Perl modules : Image::Magick and Algorithm::Cluster . It should run on Windows. Example usage: ./bitmap2md.pl --res...

Yes, it won't break an image into 16-colors tiles. It may be possible to write a script that combines several imagemagick commands to do that. Imagemagick may not be the best tool to do such a thing.

Re: Making Exodus Open Source: What license model to use?

Hi everyone, I don't want this to be like linux, where you've got 15 different flavours of Exodus. [...] Even worse would be someone picking up the main sourcecode, quickly tacking a few features on the side, and that release becomes more popular, and I lose main control over the project. In order f...
