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.
