Platform-Specific Notes
To write a Patch Code using Barcode Xpress, set the writer BarcodeType property to PatchCode, then set the writer BarcodeValue property to a value of 1 through 6.
Patch Codes require a quiet zone, which should be at least the width of 10 narrow bars. This means that if you set the MinimumBarWidth property to 5 pixels (narrow bar size), you should set the HorizontalWhiteSpace property to 50 pixels.
The minimum bar width for Patch Codes is 5.
