A generalized pixel.

A pixel object is usually not used standalone but as a view into an image buffer.

Associated Types

The underlying subpixel type.

Required Methods

Returns the number of channels of this pixel type.

Returns the components as a slice.

Returns the components as a mutable slice

Returns a string that can help to interpret the meaning each channel See gimp babl.

Returns the ColorType for this pixel format

Returns the channels of this pixel as a 4 tuple. If the pixel has less than 4 channels the remainder is filled with the maximum value

TODO deprecate

Construct a pixel from the 4 channels a, b, c and d. If the pixel does not contain 4 channels the extra are ignored.

TODO deprecate

Returns a view into a slice.

Note: The slice length is not checked on creation. Thus the caller has to ensure that the slice is long enough to present panics if the pixel is used later on.

Returns mutable view into a mutable slice.

Note: The slice length is not checked on creation. Thus the caller has to ensure that the slice is long enough to present panics if the pixel is used later on.
