Expand description

An enumeration of color types encountered in image formats.

This is not exhaustive over all existing image formats but should be granular enough to allow round tripping of decoding and encoding as much as possible. The variants will be extended as necessary to enable this.

Another purpose is to advise users of a rough estimate of the accuracy and effort of the decoding from and encoding to such an image format.

Variants

A8

Pixel is 8-bit alpha

L1

Pixel is 1-bit luminance

La1

Pixel is 1-bit luminance with an alpha channel

Rgb1

Pixel contains 1-bit R, G and B channels

Rgba1

Pixel is 1-bit RGB with an alpha channel

L2

Pixel is 2-bit luminance

La2

Pixel is 2-bit luminance with an alpha channel

Rgb2

Pixel contains 2-bit R, G and B channels

Rgba2

Pixel is 2-bit RGB with an alpha channel

L4

Pixel is 4-bit luminance

La4

Pixel is 4-bit luminance with an alpha channel

Rgb4

Pixel contains 4-bit R, G and B channels

Rgba4

Pixel is 4-bit RGB with an alpha channel

L8

Pixel is 8-bit luminance

La8

Pixel is 8-bit luminance with an alpha channel

Rgb8

Pixel contains 8-bit R, G and B channels

Rgba8

Pixel is 8-bit RGB with an alpha channel

L16

Pixel is 16-bit luminance

La16

Pixel is 16-bit luminance with an alpha channel

Rgb16

Pixel contains 16-bit R, G and B channels

Rgba16

Pixel is 16-bit RGB with an alpha channel

Bgr8

Pixel contains 8-bit B, G and R channels

Bgra8

Pixel is 8-bit BGR with an alpha channel

Unknown(u8)

Pixel is of unknown color type with the specified bits per pixel. This can apply to pixels which are associated with an external palette. In that case, the pixel value is an index into the palette.

Implementations

impl ExtendedColorType

pub fn channel_count(self) -> u8

Get the number of channels for colors of this type.

Note that the Unknown variant returns a value of 1 since pixels can only be treated as an opaque datum by the library.
