This method is designed for text retrieval application to overlay scanned form image. It overlays a form with ASCII text in a transparent mode. The form is a black and white TIFF file. The overlay will start from the top left corner of the image. The carriage return and line feed is used to advance to a new line on the form.
The image should have valid dot per inch resolution (DPI). The Image DPI will be used to scale the font size to get a proportional view.
