Barcodes

The integration of the webPDF barcode web service allows various common barcode formats to be added to PDF documents.

List of supported formats

You can generate the following barcode formats with n2pdf.

One-dimensional (linear) barcodes

One-dimensional barcodes are normally linear barcodes that are used to encode values with a sequence of bars with different thicknesses. In this type of barcode format, only this sequence is relevant, i.e., the bars’ height is not important. In fact, this is the reason why these barcodes are called one-dimensional barcodes. Accordingly,1D barcodes normally involve few, if any, requirements concerning the barcode height. In contrast, their width is subject to strict rules, as the sequence of empty spaces and bars, and their width ratio in particular, must strictly adhere to the relevant specifications without fail.

Two-dimensional barcodes

In two-dimensional barcodes, a value is encoded in a two-dimensional plane with the use of black and white pixels. 2D barcodes usually have a significantly greater information capacity than linear barcodes, but their higher complexity also means that, in some cases, they are considerably more prone to image errors. This, in turn, means that they need an error correction method. Both the height and width of 2D barcodes are subject to strict rules, as every pixel on the code can potentially contain important information. Accordingly, these formats very frequently involve requirements concerning the available heights and widths, width-to-height ratios, and the geometric shape of the barcode in general.
