Lexmark Confidential until announced PostScript emulation 63 Operator Function parameter barcodewidth String dict barcodewidth wx wy Similar to the stringwidth operator, this function returns the operand stack on the X and Y displacement of the currentpoint. A barcodeshow of the specified bar code symbol causes the displacement. For example: (0123456) > barcodewidth This operation returns two values on the stack. It indicates the change in currentpoint in the X and Y direction that results from a barcodeshow with the same data. This example specifies a bar code with the following information: • A leading quiet zone of 100 and a trailing quiet zone of 200 • A bar code height of 210 • Bars with widths of 10, 20, 30, and 40 • Spaces with widths of 9, 18, 27 and 36 It also specifies that using the Courier Bold font fully embeds the data within the code. For the EAN-8 symbology, the /Special key does not apply, and the checksum character always prints when the embedded text is specified, so /PrintCheckChar is irrelevant.
