Expand description
Decoding of netpbm image formats (pbm, pgm, ppm and pam).
The formats pbm, pgm and ppm are fully supported. The pam decoder recognizes the tuple types
BLACKANDWHITE
, GRAYSCALE
and RGB
and explicitely recognizes but rejects their _ALPHA
variants for now as alpha color types are unsupported.
