Pixel format determines attributes of pixels:

• Color channels
• Bit depth
• Linear or gamma encoded
• Premultiplied alpha

These are existing formats:

• Alpha
• Gray
• Rgb
• Rgba
• Srgb

Required methods

fn mask_over_fallback(dst: &mut [Self], mask: &[u8], src: Self)

Blend pixels with an alpha mask (slow fallback).

• dst Destination pixels.
• mask Alpha mask for compositing.
• src Source color.
