TImageEnProc.Colorize

Declaration

procedure Colorize(Hue: Integer; Saturation: Integer; Luminosity: Double);

Description

Set the hue and saturation for all pixels of the image. It also adjusts the luminosity using a multiplier.

Parameter	Description
Hue	A value between 0 and 359 (corresponding to 0 to 359 degrees around hexcone)
Saturation	A value between 0 (shade of gray) and 99 (pure color)
Luminosity	This is 1 if you don't touch the original luminosity. Whereas 1.1 would equate to 10% increase in luminosity, for example

Note:
◼Colorize is the same as setting the HSV value for each pixel with a specified hue and saturation, and the value based on the gray-scale conversion of each pixel multiplied by your luminosity value
◼A UI for this is available to your users in the Image Processing dialog
◼If the image PixelFormat is not ie24RGB or ie8p, it will be converted
