+.SH NAME
+XkbComputeShapeBounds \- Updates the bounding box of a shape
+.SH SYNOPSIS
+.B Bool XkbComputeShapeBounds
+(
+.I shape
+)
+.br
+ XkbShapePtr \fIshape\fP\^;
+.if n .ti +5n
+.if t .ti +.5i
+.SH ARGUMENTS
+.TP
+.I \- shape
+shape to be examined
+.SH DESCRIPTION
+.LP
+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.
+
+A ShapeRec contains a BoundsRec that describes the bounds of the shape. If you add or delete
+an outline to or from a shape, the bounding box must be updated.
+
+.I XkbComputeShapeBounds
+updates the BoundsRec contained in the
+.I shape
+by examining all the outlines of the shape and setting the BoundsRec to the minimum x and
+minimum y, and maximum x and maximum y values found in those outlines.
+.I XkbComputeShapeBounds
+returns False if
+.I shape
+is NULL or if there are no outlines for the shape; otherwise, it returns True.
+
+If you add or delete a key to or from a row, or if you update the shape of one of the keys in that row, you may need to update the bounding box of that row. To update the bounding box of a row, use
+.I XkbComputeRowBounds.
