Code 39 in Barcode Winforms Control - Barcode Scaling Support
The height of bar is controlled by BarHeight. The width of narrow bar is managed by BarWidth and the width of the wide bar is influenced by BarWidth and WideVSNarrow.
The width of gaps between two characters in Code 39 could be adjusted with InterCharGap. It is a multiple of X.
Increasing the width of margins around the symbol is one way to enhance the readability of the Code 39 barcode image. The control library set the left, right, top, and bottom margins separately with float values. The default value is 0.
If the breakdown parameters are unknown, 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 Code 39 will draw the barcode with reasonable parameters. The generated Code 39 is 100% compatible with ISO / IEC 16388 (2nd edition 2007-05-15).
