Patch Code

The barcode engine supports the following patch codes:

Patch Code Type	Barcode Value
Patch 1	1100
Patch 2	1001
Patch 3	1010
Patch 4 / Toggle Patch	0110
Patch 6	0011
Patch T / Transfer Patch	0101

To write a Patch Code, 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. There is no checksum for Patch Code.

The minimum bar width for Patch Codes is 5.
