Pass a valid WorkflowImage to this method, if not, the activity will throw an exception.

This activity will write the barcode symbol over the image using the rectangle defined by the Location property.

If you set the Flags property to BarcodeWriteFlags.UseColors, this activity will use the BarColor and SpaceColor properties. Otherwise, it will ignore it and use the default colors; black for bars and white for spaces.

Using colors does not apply for 1 bit per pixel images.

The BarcodeWriteFlags.UseColors and BarcodeWriteFlags.Transparent are used with all barcode types.
