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.

Type Aliases

• ChannelMap
  Alias to make uses of WithChannel less syntactically noisy.
