Indexed BMP Graphics possible?

Post by PakkyT »

Short version: According this this post the answer is no?

Slightly longer version is I am learning CircuitPython (an offshoot of MicroPython which of course is based on Python) to program microcontroller boards. When using a TFT display bitmaps need to be an indexed color profile. The full description on how to do this with Gimp is here...

which I have but I would much rather use GC for converting to an indexed bitmap. So still not possible?

The export of index BMPs is currently not supported.

Just export as a GIF to get an indexed version.

Unfortunately, CircuitPython only supports bitmaps I believe. Part of that is likely how it assigns graphic data to pixels and the other due to sometimes limited RAM in the micros that may not have enough to do things like uncompress GIFs, JPGs, etc.

I did one last night with Gimp and it was easy enough. Just thought it would be nice if GC did it because your solution would probably be more straightforward. Even loading Gimp takes too long just to index a tiny bitmap. 1st world problems! I will manage. :lol:
