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. +.SH STRUCTURES +.LP +.nf + +typedef struct _XkbShape { + Atom name; /\(** shape's name */ + unsigned short num_outlines; /\(** number of outlines for the shape */ + unsigned short sz_outlines; /\(** size of the outlines array */ + XkbOutlinePtr outlines; /\(** array of outlines for the shape */ + XkbOutlinePtr approx; /\(** pointer into the array to the approximating outline */ + XkbOutlinePtr primary; /\(** pointer into the array to the primary outline */ + XkbBoundsRec bounds; /\(** bounding box for the shape; encompasses all outlines */ +} XkbShapeRec, *XkbShapePtr; + +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; + +.fi +.SH "SEE ALSO" +.BR XkbComputeRowBounds (__libmansuffix__) + |
