Two additional option checkboxes have been added to the dialog, Extra1 and Extra2. These will normally be left unchecked. They do, however, provide for extra functions that are specific to particular barcode types. For details see the Barcodes HELP system.
The dialog also contains OK and Cancel buttons. Pushing the OK button causes dBarcode to close the dialog and regenerate the barcode image for display in the Image area (or report an error if the image cannot be generated).
Pushing the Cancel button causes the dialog to be closed without affecting the currently displayed barcode image.
