Enum ImageMaskMode

source
pub enum ImageMaskMode {
    A,
    B,
    G,
    R,
    Luminance,
}
Expand description

Defines how the A8 image mask pixels are to be derived from a source mask image.

Variants§

§

A

Alpha channel.

If the image has no alpha channel masks by Luminance.

§

B

Blue channel.

If the image has no color channel fallback to monochrome channel, or A.

§

G

Green channel.

If the image has no color channel fallback to monochrome channel, or A.

§

R

Red channel.

If the image has no color channel fallback to monochrome channel, or A.

§

Luminance

Relative luminance.

If the image has no color channel fallback to monochrome channel, or A.
