Module photon::colour_spaces

Image manipulation effects in HSL, LCh and HSV.

Functions

darken_hsl	Darken the image by a specified amount in the HSL colour space.
darken_hsv	Darken the image's colours by a specified amount in the HSV colour space.
darken_lch	Darken the image by a specified amount in the LCh colour space.
desaturate_hsl	Desaturate the image by a specified amount in the HSL colour space.
desaturate_hsv	Desaturate the image by a specified amount in the HSV colour space.
desaturate_lch	Desaturate the image by a specified amount in the LCh colour space.
hsl	Image manipulation effects in the HSL colour space.
hsv	Image manipulation in the HSV colour space.
hue_rotate_hsl	Shift hue by a specified number of degrees in the HSL colour space.
hue_rotate_hsv	Shift hue by a specified number of degrees in the HSV colour space.
hue_rotate_lch	Shift hue by a specified number of degrees in the LCh colour space.
lch	Apply gamma correction. Image manipulation effects in the LCh colour space
lighten_hsl	Lighten an image by a specified amount in the HSL colour space.
lighten_hsv	Lighten an image by a specified amount in the HSV colour space.
lighten_lch	Lighten an image by a specified amount in the LCh colour space.
saturate_hsl	Increase the image's saturation by converting each pixel's colour to the HSL colour space and increasing the colour's saturation.
saturate_hsv	Increase the image's saturation in the HSV colour space.
saturate_lch	Increase the image's saturation in the LCh colour space.
