Declaration
uchar MGLAPI MGL_halfTonePixel(
int x,
int y,
uchar R,
uchar G,
uchar B)
Prototype In
mgraph.h
Parameters
x |
x pixel coordinate |
y |
y pixel coordinate |
R |
Red component for pixel color |
G |
Green component for pixel color |
B |
Blue component for pixel color |
Return Value
Color index for the pixel in MGL halftone palette
Description
This function computes the color index for a specified 24 bit RGB pixel value in the standard MGL halftone palette, and can be used to perform real-time dithering of pixel values from RGB colors to color index colors. This routine uses a fast table lookup and an 8x8 ordered dither to do the conversion.
