Abstract
An expandable drawing surface is described. In various embodiments, a drawing surface manager is configured to cause a size of a drawing surface to expand dynamically to provide a user with a truly infinite drawing surface such that the user is not limited for space in any direction. To do so, the drawing surface manager creates and displays new pages for the drawing surface as the user scrolls in any direction. The new pages are displayed proximate existing pages such that the user is presented with a continuous drawing surface on which the user can work seamlessly. In one or more embodiments, a memory manager is configured to provide efficient memory techniques such that, at any point of time, only data associated with visible pages of the drawing surface is loaded onto a memory.
