* Add support for additional delta encoding used for dino, donna, donnatras and dough character faces data, in the 'disk0' file. A 'DLTA' tag is used, following by data size (big endian dword) and the delta encoded data. | * Add support for additional delta encoding used for dino, donna, donnatras and dough character faces data, in the 'disk0' file.

** DLTA chunks can be decompressed using the algorithm you can find in section 2.2.2 of this document[http://mediasrv.ns.ac.yu/extra/fileformat/animation/iff/anim7.txt]. Right now the packed bitmap are directly transformed into color-index images for ScummVM, but this must be changed to work with DLTA. The right way to do this would be: unpack bitmap (previous frame) into bitplanes, apply DLTA, transform bitplanes into color-index mode for use with ScummVM. | |||
