Module cosmic::iced_widget::renderer::graphics::image::image_rs::codecs::pnm

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 explicitly recognizes but rejects their _ALPHA variants for now as alpha color types are unsupported.
