Abstract
A drawing application provides functionality for assisting the user in performing freehand drawing. The user can place virtual stencils on the screen, and can manipulate the stencils in various ways. The stencils can be used as guides for freehand drawing and/or to transform freehand drawings into more precise shapes. In general, the stencils do not form part of the final graphical document being created (or edited), but are used to assist the creation (or editing) of the document, in a manner that is analogous to the use of physical stencils in when drawing on paper or other physical medium. The stencils can be used for straightening lines, for constraining the effect of drawing or painting, and/or as a visual guide for performing any drawing operations. The user can cause the stencils to be dismissed and/or hidden at any time, so that the graphical document can be viewed without the overlaying stencils.
