Valid image types in leptonica:
Pix: 1 bpp, with and without colormap
Pix: 2 bpp, with and without colormap
Pix: 4 bpp, with and without colormap
Pix: 8 bpp, with and without colormap
Pix: 16 bpp (1 spp)
Pix: 32 bpp (rgb, 3 spp)
Pix: 32 bpp (rgba, 4 spp)
FPix: 32 bpp float
DPix: 64 bpp double
Notes:
(1) The only valid Pix image type with alpha is rgba.
In particular, the alpha component is not used in
cmapped images.
(2) PixComp can hold any Pix with IFF_PNG encoding. Contents:
