XkbComputeShapeTop(3)                           XKB FUNCTIONS                          XkbComputeShapeTop(3)



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

SYNOPSIS
       Bool XkbComputeShapeTop ( shape, bounds_rtrn )
             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 func-tions functions
       tions 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  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 out-lines. outlines.
       lines.  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;
