324 If you encode an image without alpha with palette, don't forget to put value 255 in each A byte of the palette.
326 When decoding, by default you can ignore this palette, since LodePNG already
327 fills the palette colors in the pixels of the raw RGBA output.

415 the encoder writes the red one. For palette PNGs: When decoding, the RGB value
416 will be stored, not a palette index. But when encoding, specify the index of
417 the palette in background_r, the other two are then ignored.
522 is implemented: if a palette index is out of bounds given the palette size,
571 like AUTO, but never choose palette color type. For small images, encoding
572 the palette may take more bytes than what is gained. Note that AUTO also
573 already prevents encoding the palette for extremely small images, but that may
