XKB FUNCTIONS                            XkbComputeShapeTop(3x11)



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

SYNOPSIS
     cc [ flag... ] file... -lX11 [ library... ]

     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.  XkbCompu-
     teShapeTop 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;
