XkbComputeShapeTop(3)						   XKB FUNCTIONS					     XkbComputeShapeTop(3)

NAME

       XkbComputeShapeTop - Determines the bounding box of the top surface of a shape

SYNOPSIS

       Bool XkbComputeShapeTop (XkbShapePtr shape, XkbBoundsPtr bounds_rtrn);

ARGUMENTS

       - shape
	      shape to be examined

       - bounds_rtrn
	      backfilled with the bounding box for the shape

DESCRIPTION

       Xkb  provides  a  number of convenience functions to help use a keyboard geometry.  These include functions to return the bounding box of a
       shape's top surface and to update the bounding box of a shape row or section.

       A shape is made up of a number of outlines. Each outline is a polygon made up of a number of points. The bounding box of a shape is a  rec-
       tangle that contains all the outlines of that shape.

       XkbComputeShapeTop  returns  a  BoundsRec that contains two x and y coordinates. These coordinates describe the corners of a rectangle that
       contains the outline that describes the top surface of the shape. The top surface is defined to be the approximating outline if the  approx
       field  of  shape  is not NULL. If approx is NULL, the top surface is defined as the last outline in the shape's array of outlines.  XkbCom-
       puteShapeTop returns False if shape is NULL or if there are no outlines for the shape; otherwise, it returns True.

STRUCTURES

       typedef struct _XkbBounds {
	    short     x1,y1;	/* upper left corner of the bounds, in mm/10 */
	    short     x2,y2;	/* lower right corner of the bounds, in mm/10 */
       } XkbBoundsRec, *XkbBoundsPtr;
