Module photon_rs::monochrome

Monochrome-related effects and greyscaling/duotoning.

Functions

b_grayscale	Convert an image to grayscale by setting a pixel's 3 RGB values to the Blue channel's value.
decompose_max	Uses a max. decomposition algorithm to convert an image to greyscale.
decompose_min	Uses a min. decomposition algorithm to convert an image to greyscale.
desaturate	Desaturate an image by getting the min/max of each pixel's RGB values.
g_grayscale	Convert an image to grayscale by setting a pixel's 3 RGB values to the Green channel's value.
grayscale	Convert an image to grayscale using the conventional averaging algorithm.
grayscale_human_corrected	Convert an image to grayscale with a human corrected factor, to account for human vision.
grayscale_shades	Employ only a limited number of gray shades in an image.
monochrome	Apply a monochrome effect of a certain colour.
r_grayscale	Convert an image to grayscale by setting a pixel's 3 RGB values to the Red channel's value.
sepia	Convert an image to sepia.
single_channel_grayscale	Convert an image to grayscale by setting a pixel's 3 RGB values to a chosen channel's value.
threshold	Threshold an image using a standard thresholding algorithm.
