Struggling to create high-quality barcode images, or using low-quality barcode fonts and finding they don't work well enough in your environment? Alver Valley Software's product 'AVS Barcode Source' can be used to create barcode images and save them in graphics format files suitable for use in pre-press, DTP or labelling applications. All major linear (1D) barcode formats are supported, including Code 39 (plus extended mode), Code 128, Codabar, EAN13, and the 2-of-5 family including Interleaved, Industrial, Matrix, IATA and COOP.
