ReadBAR features

ReadBAR, the barcode reading component for Delphi, allows the reading of a code 3of9 barcode from a scanned image for data capture or document indexing. The program allows use of a checksum to verify accurate read, and can handle skewed images without de-skewing. ReadBAR is intended to be used on a consistent, previously tested barcode, preferably one produced in-house and under the control of the developer to assure readability. Users of ReadBAR include county tax collectors, medical claims processing, and invoice processing.

Easy to use
Include the barcode reader unit in your uses clause, load a bitmap of any sort (TifIMG 16/32 does this), and pass the desired rectangle to ReadBAR. It will return the ASCII code of the bar. A True-Type 3of9 font is included

C++Builder DLL available for C Use

No de-skewing
ReadBAR handles a skewed barcode as long as there is a straight line from upper left to lower right, or upper right to lower left, typically within 10 - 15 degrees. This is designed to handle the skewing that is a normal part of production scanning. If severe de-skewing or rotating is required, TifIMG 16/32 can provide these functions.

Fast
ReadBAR will return so quickly that it is possible to do many reads and compare results in one pass ... see below.

Automatic seek
ReadBAR is given the starting rectangle to use. This may be purposely set above the anticipated area and stepped into the image to seek the barcode, thus eliminating a requirement for accurate page registration from the scanner. In other words, the image does not have to be carefully positioned.
