This routine determines whether the passed rectangular area falls within the clipping region.

Structures:

        typedef ByteEnum TestRectReturnType;
TRRT_OUT,			/* rectangle completely out of region */
TRRT_PARTIAL,			/* rectangle partially in region */

GrTextWidth()

word	GrTextWidth(
        GStateHandle		gstate,				/* subject GState */
        const	Chars	* str,				/* text string to check */
        word		size);				/* maximum number of
						 * characters to check */

Compute the space the passed text string would require in a line of text. Use GrGetTextBounds() to determine the area necessary to render the text.

Include: graphics.h
