Abstract

A form document editor having a form descriptor table defining editable graphics and text areas with a page comprised of a background bitmap image of a background of the page, a graphics bitmap image of graphics appearing in a graphics area of the page, and a text buffer of text appearing in a text area of the page. The editor includes a graphics editor operating on the graphics bitmap image and a text editor for editing the text in the text buffer. The background and graphics bitmap images and text buffer are combined into a composite page image for display and storage of the form document. A document is retrieved from storage for editing is provided to the editor as a background bitmap. An area of a page may contain autofill data and the editor includes an intelligent autofill data import mechanism for inserting user provided data into the autofill data upon detecting a user data import indicator, with the user data replacing the indicator in the autofill data.
