Can anyone recommend some PC software (preferably free / donate / share) that can create & edit raw bitmaps in RGB565 (16 bit colour) format, and most importantly can save the bitmap in vertical raster, not the usual horizontal raster?
This is the sort of thing you'd use to create images for small Arduino etc colour TFT LCD displays. The Raw pixels website online app can't do horizontal raster.
Thanks in advance for any suggestions.
