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.
