nsgif_bitmap_fmt

enum fl::third_party::nsgif_bitmap_fmt

NSGIF nsgif_bitmap_t pixel format.

All pixel formats are 32 bits per pixel (bpp). The different formats allow control over the ordering of the colour channels. All colour channels are 8 bits wide.

Note that the GIF file format only supports an on/off mask, so the alpha (A) component (opacity) will always have a value of 0 (fully transparent) or 255 (fully opaque).
