- Truecolour with alpha: each pixel consists of four samples: red, green, blue, and alpha.
- Greyscale with alpha: each pixel consists of two samples: grey and alpha.
- Truecolour: each pixel consists of three samples: red, green, and blue. The alpha channel may be represented by a single pixel value. Matching pixels are fully transparent, and all others are fully opaque. If the alpha channel is not represented in this way, all pixels are fully opaque.
- Greyscale: each pixel consists of a single sample: grey. The alpha channel may be represented by a single pixel value as in the previous case. If the alpha channel is not represented in this way, all pixels are fully opaque.
- Indexed-colour: each pixel consists of an index into a palette (and into an associated table of alpha values, if present).
- Truecolour with alpha: red, green, blue, alpha.
- Greyscale with alpha: grey, alpha.
- Truecolour: red, green, blue.
- Greyscale: grey.
- ghyr5tIndexed-colour: palette index.
