Reads barcodes from image files. Softek Barcode Toolkit for Linux reads barcodes from TIF and JPG files. Imaging applications can use the toolkit to read barcodes strings from scanned documents and cross reference them against database tables. The toolkit supports both Shell and 'C' programming interfaces and supports all the common barcode formats. All licenses include 12 months Support and Upgrade Cover

The Softek Barcode Toolkit enables application programmers to read barcodes from image files. The image files can be from any source, but will typically come from a scanner or computer fax modem. The barcode recognition engine is contained in a single library file, which makes product upgrades a simple matter. The application programmer can use either the Shell or the 'C' interface. The choice of interface will depend on the type of language being used and the type of application to be developed.

A few lines of code are all that is needed to read a barcode from an image. As can be seen from this example using the 'C' interface:

hBarcode = STCreateBarCodeSession() ;

bar_count = STReadBarCode(hBarcode, file, 0, &bar_codes, &bar_codes_type) ;

for (i = 0; i < bar_count; i++)

{

printf ('Barcode = %s\n', bar_codes[i]) ;

}

Using the Shell interface is even simpler:

$ ./bardecode -t any -j 1 -f file.tif

Barcode Widths:

The main requirement is for each black or white bar in a barcode to be clearly visible on the image. All barcodes have at least 2 sizes of bar and the image needs to be of high enough quality to show this. For example, a Code 39 barcode consists of 9 bars per character, of which 3 must be wide and 6 must be narrow. The wide bars should be around 2.5 times the size of the narrow bars - but for simplicity we will say 2 times the size. This means that each character needs at least 12 pixels in an image. This assumes that each pixel in the image lies either entirely in a black bar or entirely in a white bar. In practise, this isn't possible and so the resolution should allow around 36 pixels per character.

So, to encode a string of 10 characters (including the start and stop *) you will need at around 360 pixels. If the barcode is 1 inch wide on the paper then you will need to scan at a resolution of around 400 DPI. If the barcode is 2 inches wide then you will need to scan at a resolution of at least 200 DPI.

Some types of barcode have more than 2 widths of bar and a higher resolution still will be needed to ensure that the different widths can be distinguished on the image.

As for barcode height - if you have a very wide barcode then you need to ensure that it is high enough to cope with any skewing that takes place when the image is scanned.

In summary - the success of a project can depend on specifying the correct barcode size and image resolution.

Code 39 Number of Characters 10, Minimum Number of Pixels (approx) 340

Code 2 of 5 (interleaved) Number of Characters 10, Minimum Number of Pixels (approx) 190

Code 128 (code set A) Number of Characters 10, Minimum Number of Pixels (approx) 280

Code 128 (code set B) Number of Characters 10, Minimum Number of Pixels (approx) 280

Code 128 (code set C) Number of Characters 10, Minimum Number of Pixels (approx) 170

EAN-13 Number of Characters 13, Minimum Number of Pixels (approx) 190

EAN-8 Number of Characters 8, Minimum Number of Pixels (approx) 140

UPC-A Number of Characters 12, Minimum Number of Pixels (approx) 190

UPC-E Number of Characters 8, Minimum Number of Pixels (approx) 120
