decode_pnm

procedureextensionsince 0.28.0Source

Decodes a PGM (P2, P5) to GRAY8 or a PPM (P3, P6) to RGB8. Samples are scaled to 8 bits.

Example↗
image, ok := decode_pnm(cast([] u8) "P2\n2 1\n255\n0 255\n");
defer deinit(*image);
assert(ok && image.format == .GRAY8 && image.pixels[1] == 255);
decode_pnm :: (
    data: [] u8,
    max_pixels: s64 = DEFAULT_MAX_PIXELS
) -> (image: Image, ok: bool, error: string)

Parameters

data: [] u8
max_pixels: s64 = DEFAULT_MAX_PIXELS

Returns

image: Image
ok: bool
error: string
