Abstract: A method and system in a data processing system for modifying an image source data file to compensate for distortions resulting from a projection of an image source onto a surface that is not perpendicular to an image source projection system. A data processing system image source data file is identified and a test pattern is displayed utilizing a data processing system visual output device. A user is permitted to enter a distortion compensation factor, the displayed test pattern is modified utilizing the distortion compensation factor. Once a final distortion compensation factor is selected in response to the appearance of the modified test pattern, the data processing system image source data file is modified, utilizing the selected distortion compensation factor, thereby enhancing the projection of an image source onto a surface that is not perpendicular to an image source projection system.

Abstract: The present invention allows the inclusion of a place mark in an electronic mail item. The place mark serves to identify and link an on-line reference to the mail item. When a user sends the mail item to a recipient, the place mark but not the reference goes with the item. Upon receipt, the recipient may select the place mark during review of the mail item and the on-line reference will be automatically called and displayed. Upon completing review of the reference, the recipient may transfer control from the on-line reference to the mail item without having to back out of the reference and then initiate the electronic mail.
