Blank page detection can be performed on any image (bitonal, grayscale, or color) within the recognition engine's memory space. The DetectBlankPage Method will consider an image blank if there is a small percentage of noise, especially noise around the edge of the image usually created as a result of scanning.
The DetectBlankPage Method will return TRUE if the image is blank, or FALSE if any text of graphics are found on the page. The image will not be modified from this process.
