Abstract

Association of ink information with image files is described. An image file is created and ink information is parsed and inserted into comment or arbitrary data fields of the image file. The image file with additional ink information may be used by both ink-enabled applications/environments and non-ink-enabled applications environments. The ink-enabled applications/environments may extract the ink information and use the original ink while the non-ink-enabled applications/environments may use the image information to permit the end user to see the visual representation of the ink.
