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
       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 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;
