MGL_setBackColor

Sets the currently active background color.

Declaration

void MGLAPI MGL_setBackColor(
color_t color)

Prototype In

mgraph.h

Parameters

color | New background color value

Description

Sets the current background color value. The background color value is used to clear the display and viewport with the MGL_clearDevice and MGL_clearViewport routines, and is also used for filling solid primitives in the MGL_BITMAP_OPAQUE fill mode.

Note that the value passed to this routine is either a color index or a color value in the correct packed pixel format for the device context. Use the MGL_packColor routine to pack 24 bit RGB values for RGB device contexts.
