Barcodes are created with the help of graphics. The codes used widths of black bars and spaces. The width of the spaces and bars must be printed within precise tolerances, so that is readable by most bar code readers and scanners. Currently bar codes are created for Microsoft Windows with three types of charts: bitmaps, fonts and metafiles.

Bitmap is actually a series of small dots, which are called pixels. The image is created with a resolution of the printer anywhereTo create a barcode. Characters, on the other side, there are no graphs in the strict sense of the term, but can still be used to create barcodes. A font is actually a set of graphics that are assigned for each character in a certain set of characters. Symbols, because most of the bar code data encryption, which operate through the allocation of certain characters in the bar and some models of space, we have the fonts to create bar codes.

The most commonly used to create bar code is a vector-style graphics.This graph consists of a series or sequence of instructions to explain how the image is converted. Metafile fall into this category. The Encapsulated PostScript graphics are also known as vector graphics. Not order to we use a device of such images. This format supports the exact dimensions for all graphic elements. The amount of memory is stored in a small metafile. As a plus, commonly used Windows programs and various programming languages provide built-in support for addressing theMetafile.

Many companies offer advanced image generator barcode. This software helps to create barcode image files quickly in a variety of formats, including JPEG, BMP, Photoshop, Quark, CorelDraw, and others. Many of these programs are very user-friendly and can also be used by anyone without experience of bar codes. We can also bar codes on the Internet.
