CREATING IMAGES FOR DISPLAYING OR PRINTING ON LOW-CONTRAST BACKGROUND

摘要

Techniques for automatically adding special effects to an image to be overlaid on a low-contrast background are presented. A stroke or an intervening layer of a color contrasting with the background color is automatically added to provide a contrasting color around the edges of visible image content in an image container of an electronic document. The technique may be applied to entire libraries of images to generate variant images that are visually perceptible when displayed or printed on low-contrast background colors.
