Valid Data of UPC-A Generator for Winforms:

2 or 5 digits supplement barcode could be added to accompany EAN-13. To encode supplement barcode, please select UPCA_AddOn2 or UPCA_AddOn5, then input supplement data. The size of the supplement barcode is adjustable. AddOnHeight defines the height of the add-on symbol. It is a multiple of primary bar height, Y. AddOnMargin is the space between barcode and add-on symbol, measured in pixel.

The width of module bar is managed by BarWidth; the height of bar is controlled by BarHeight.

Increasing the width of margins around the symbol is one way to enhance the readability of the UPC-A barcode image. The control library set the left, right, top, and bottom margins separately with float values.

If the breakdown parameters are not provided, you can set the width and height of the barcode image directly. Once you enabled the image resize function, you only need to provide the size of entire barcode image. This intelligent UPC-A will draw the barcode with reasonable parameters. The generated UPC-A is 100% compatible with GS1 Barcode Standards.

With Terrek Barcode Winforms Control DLL, UPC-A is created as high quality GIF, JPEG, or PNG graphic images. Tiff and Bitmap are supported as well. Please ensure the accordance of image format and suffix of image file name.

DPI (Dots per inch) is used commonly as the measure of printing resolution. The resolution of image generated by UPC-A generator could be managed with DPI.

In case of any specified requirement of the image orientation, image rotation function is added to the control library. Rotation angles of 90, 180, and 270 degrees are supported.
