        sword		left,				/* bounds to be invalidated */
        sword		top,
        sword		right,
        sword		bottom);

Invalidate the passed rectangular area. This area will be redrawn.

GrLabel()

void	GrLabel(
        GStringHandle		gstate,			/* subject GState */
        word		label);			/* label to write to GString */

Write the passed label into the passed GString.

Include: gstring.h

GrLoadGString()

GStringHandle GrLoadGString(
        Handle		han,				/* handle of GString source */
        GStringType		hanType,				/* handle type */
        word		vmBlock);				/* if VM file, handle of VM block */

Load a graphics string from a file. Used with stream, VM, and pointer addressed GStrings.

When done with the GString, you may free it via GrDestroyGString() .

Include: gstring.h

GrMapColorIndex()

RGBColorAsDWord GrMapColorIndex(
        GStateHandle		gstate,			/* GState to use for mapping */
        Color		c);			/* source color to be mapped */

Map a color index to its RGB equivalent using the color mapping scheme of the passed GState.

Include: graphics.h

GrMapColorRGB()

RGBColorAsDWord GrMapColorRGB(
        GStateHandle		gstate,			/* GState to use for mapping */
        word		red,			/* RGB values to map */

GrMoveReg()

void	GrMoveReg(
        Region	* reg,	/* pointer to region */
        sword	xOffset,	/* amount to shift horizontally */
        sword	yOffset);	/* amount to shift vertically */

Moves a region a given amount. Note that this operation affects only the region's data structure. The region must be redrawn or used in some other way for the changes to have any visible effect.

Include: graphics.h

GrMoveTo()
