Abstract: Facilitating digital writing on a tablet screen includes providing a viewing screen corresponding to the tablet screen, superimposing on the viewing screen an authoring screen for a user to provide digital writing, the authoring screen being a magnified portion of the viewing screen, showing a mapping portion on the viewing screen, where the mapping portion corresponds to the portion of the viewing screen being magnified into the authoring screen, and projecting on to the viewing screen writing entered by the user in the authoring screen. The authoring screen is semi-transparent and writing and the mapping portion on the viewing screen are viewable through the authoring screen. The authoring screen may be superimposed over an entirety of the viewing screen. Writing provided on the viewing screen may be presented as faded strokes. A user may pan the authoring screen to facilitate entering writing into different parts of the viewing screen.

Abstract: One embodiment of the present invention provides a system that sizes a polygon in a layout. During operation, the system receives a polygon which is to be sized by a sizing amount. The system then selects one or more vertices of the polygon. Next, the system replaces each selected vertex with a set of replacement vertices, and subsequently assigns a projection path to each replacement vertex in the set of replacement vertices. The system next performs a sizing operation on the polygon according to the sizing amount. During the sizing operation, the system moves each replacement vertex in the set of replacement vertices along the assigned projection path, thereby creating a clipping on the angle associated with the selected vertex. Furthermore, this sizing operation is continuous: similar output polygons are obtained for similar sizing amounts.
