Create Barcodes
Author: admin
Barcodes are created with the help of graphics. The codes make use of widths of white spaces and black bars. The widths of the spaces and bars must be printed within exact tolerances in order to be readable by most bar code readers and scanners. Presently, barcodes are created by Microsoft Windows using three main graphic types: bitmaps, fonts and metafiles.
Bitmap is actually an array of small dots which are called pixels. An image is created with the dot resolution of any printer to create a barcode. Fonts, on the other hand, are not graphics in strict sense of the term but they can still be used to create bar codes. A font is in fact a collection of graphic elements that are assigned to each character in any given set of characters. Since most bar code symbologies encode data by mapping specific characters to specific bar and space patterns, we make use of fonts to create bar codes.
The most widely used method to create barcode is a vector style graphic. Such a graphic consists of a series or sequence of instructions to describe how an image is cast. Metafiles fall in this category. Encapsulated postscript graphics are also designated as vector graphic. We do not have to use a device for such graphics. This format supports precise dimensions for all graphic elements. The amount of memory stored in a metafile is small. As a plus, commonly used Windows programs and several programming languages provide built-in support for handling metafiles.
Many modern businesses offer barcode image generators. This software helps in creating barcode images files in quickly in a range of formats like JPEG, BMP, Photoshop, Quark, CorelDraw and others. Many of these software programs are very user friendly and can even be used by someone with no bar code experience. We can even create barcodes on the internet.

Modern day computers are designed to read a barcode sent through fax. This process is completed by a certain program in the PC that allows the computer to automatically read a barcode at the top and bottom of a fax coversheet. Instructions encoded in the barcode direct the computer to make a correct data entry or any other function. Special fax servers are able to handle the receipt of all faxes, significantly reducing the need for standard fax machines and papers.
Barcode fax technology provides an economical, secure, and smart way to integrate inbound fax handling with the computer application. Most of the faxes received this way are automatically passed to the application as PDF or Tagged Image File (TIF). When inbound mails are received, they get posted to a catcher application in the computer. The post usually contains data like date and time of fax receipt, file type (PDF or TIF), number of Pages, fax Status, number of Barcodes scanned, Barcode value, Barcode sequence, Barcode symbology and Barcode page number. It also contains fax images.
We can capture data from barcodes within a fax and use it for routing purposes or relational data tracking by data capture via barcode scanning. The system scans and reads the barcode image on a document when a fax is received. This process has proved very optimal for companies with a huge volume of data that need an automated way to read a value on a fax, in order to automatically associate that fax with other data. It is preferred for routing purposes also. It is ideal for tracking and processing many business documents.
