True, but TFPCustomImage is abstact wrt memory layout and doens't provide row level access, only pixel level access. Only TFPMemoryImage adds the memory access, but IIRC only 64-bit pixels. (16-bit RGBA) While these abstractions make it easy to make fp/fcl-image somewhat complete, they are also very memory hungry and slow. IIRC I accelerated loading/saving simple 8-bit BMP images 20 to 50 times in my work code. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
