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

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

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

Returns a view into a slice.

Panics

If the slice it not long enough this method will panic.

Returns mutable view into a mutable slice.

Panics

If the slice it not long enough this method will panic.

Apply the function f to each channel except the alpha channel. Apply the function g to the alpha channel. Works in-place.

Provided Methods

Apply the function f to each channel of this pixel.

Apply the function f to each channel of this pixel.

Apply the function f to each channel except the alpha channel. Apply the function g to the alpha channel.

Apply the function f to each channel of this pixel and other pairwise.

Apply the function f to each channel of this pixel and other pairwise. Works in-place.
