Patent ID: 6912689

Claim:
A method for facilitating substitution of a full bitmap version of a graphical image with a line drawing version of the graphical image in a graphical presentation, the method comprising: receiving the full bitmap version of the graphical image; producing the line drawing version of the graphical image from the full bitmap version of the graphical image, wherein the line drawing version is used in place of the graphical image in the graphical presentation, is substantially the same size as the graphical image, and includes the outlines of shapes that are present in the full bitmap version; wherein displaying the line drawing version of the graphical image requires less data to be retrieved than displaying the full bitmap version of graphical image; inserting the line drawing version of the graphical image into a page in the graphical presentation; and linking the full bitmap version of the graphical image into the graphical presentation so that selecting the line drawing version of the graphical image causes the full bitmap version of the graphical image to be displayed, and wherein selecting the full bitmap version of the graphical image causes the graphical image to replace the line drawing version and to occupy the same space as the line drawing version.
