MGL_rgbColor

Computes a packed MGL color from a 24 bit RGB tuple.

Declaration

color_t MGLAPI MGL_rgbColor(
MGLDC *dc,
uint R,
uint G,
uint B)

Prototype In

mgraph.h

Parameters

dc | Device context to map color with
R | Red component of color to map (0 - 255)
G | Green component of color to map (0 - 255)
B | Blue component of color to map (0 - 255)

Return Value

Packed MGL color closest to specified RGB tuple.

Description

This function computes the packed MGL color value from a specific 24 bit RGB tuple for a device context. If the device context is an RGB device context or an 8 bit device in RGB dithered mode, this value simply returns the proper packed MGL pixel value representing this color (the same as MGL_packColor would). However if the device context is a color index device, the color palette is searched for the color value that is the closest to the specified color. This function allows you to specify a color given an RGB tuple, and will work in color index modes as well with any color palette.
