feat: Add support for translating layer flags
Sometimes Aseprite is still using the very old palette chunk (0x0004), e.g. when creating an indexed file with C64 palette (no transparency). As stated by the specs: Aseprite v1.3.5 writes this chunk if the palette doesn't have alpha channel and contains 256 colors or less (because this chunk is smaller) This commit adds support for the chunk. fixes TheCyberRonin#24

There was a problem hiding this comment.
Tested it out with the provided Aseprite file, it seems to have the necessary data. Thanks so much for contributing! I'll see about rolling a new revision so that it's updated on NPM.

Thanks for merging and sharing. I'm using the parser with a build script to export images but unfortunately the palette was missing. |
