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;
