Signature Checker - Version 1.0 Signature Checker is an audit tool designed to quickly look at an area of a scanned document and determine if it contains any data. It does this by looking at the percentage of black and white pixels. It does not compare and validate a signature; it only looks to see if something exists in a specified area of a file. The program has been designed to process batch process single page tiff image files. It can be set to process more than one job, with a job being a set of instructions (settings). So a file could be processed to look for a signature, then processed again to look at an area for initials etc. If the documents have already been scanned and saved as PDFs or PDF output is desired please contact us.
