Expand description

A generalized pixel.

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

Required Associated Types

The scalar type that is used to store each channel in this pixel.

Required Associated Constants

The number of channels of this pixel type.

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

Required Methods

Returns the components as a slice.

Returns the components as a mutable slice

👎Deprecated since 0.24.0: Use channels() or channels_mut()

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

👎Deprecated since 0.24.0: Use the constructor of the pixel, for example Rgba([r,g,b,a]) or Pixel::from_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 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 prevent 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 prevent panics if the pixel is used later on.

Convert this pixel to RGB
