Module imageproc::map

Functions for mapping over pixels, colors or subpixels of images.

Traits

WithChannel

The type obtained by replacing the channel type of a given Pixel type. The output type must have the same name of channels as the input type, or several algorithms will produce incorrect results or panic.

Functions

as_blue_channel

Creates an RGB image by embedding a grayscale image in its blue channel.

as_green_channel

Creates an RGB image by embedding a grayscale image in its green channel.

as_red_channel

Creates an RGB image by embedding a grayscale image in its red channel.

blue_channel

Creates a grayscale image by extracting the blue channel of an RGB image.

green_channel

Creates a grayscale image by extracting the green channel of an RGB image.

map_colors

Applies f to the color of each pixel in the input image.

map_colors2

Applies f to the colors of the pixels in the input images.

map_colors_mut

Applies f to the color of each pixel in the input image in place.

map_pixels

Applies f to each pixel in the input image.

map_pixels_mut

Applies f to each pixel in the input image in place.

map_subpixels

Applies f to each subpixel of the input image.

map_subpixels_mut

Applies f to each subpixel of the input image in place.

red_channel

Creates a grayscale image by extracting the red channel of an RGB image.
