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.
