Barcode

A barcode represents data associated with an object in a form that optical machines can read. Early barcode systems encoded data through varying widths and spacing of parallel lines—these are linear or one-dimensional (1D) barcodes. Barcodes later evolved into two-dimensional (2D) geometric patterns such as rectangles, dots, and hexagons. Although 2D systems use a series of symbols, they are still commonly called barcodes. Barcodes were originally scanned by dedicated optical scanners called barcode readers; scanners and decoding software are now widely used on desktop printers, smartphones, and other devices. Foxit PDF SDK provides APIs to generate barcode bitmaps from a given string. The table below lists the barcode types supported by Foxit PDF SDK.
