[−][src]Enum image::ExtendedColorType
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
Pixel is 1-bit luminance
Pixel is 1-bit luminance with an alpha channel
Pixel contains 1-bit R, G and B channels
Pixel is 1-bit RGB with an alpha channel
Pixel is 2-bit luminance
Pixel is 2-bit luminance with an alpha channel
Pixel contains 2-bit R, G and B channels
Pixel is 2-bit RGB with an alpha channel
Pixel is 4-bit luminance
Pixel is 4-bit luminance with an alpha channel
Pixel contains 4-bit R, G and B channels
Pixel is 4-bit RGB with an alpha channel
Pixel is 8-bit luminance
Pixel is 8-bit luminance with an alpha channel
Pixel contains 8-bit R, G and B channels
Pixel is 8-bit RGB with an alpha channel
Pixel is 16-bit luminance
Pixel is 16-bit luminance with an alpha channel
Pixel contains 16-bit R, G and B channels
Pixel is 16-bit RGB with an alpha channel
Pixel contains 8-bit B, G and R channels
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
[src]
pub fn channel_count(self) -> u8
[src]
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.
