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 geom-
     etry.  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  rectangle  that
     contains all the outlines of that shape.

     XkbComputeShapeTop  returns  a  BoundsRec that contains two x and y coordi-
     nates. 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.  XkbComputeShapeTop 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;
