Remarks

The MicroPDF417BarcodeSymbolSize enumeration is used as the type for the MicroPDF417BarcodeWriteOptions.SymbolSize property and can be used to control the symbol size to use when writing MicroPDF417 barcodes.

When the value of MicroPDF417BarcodeWriteOptions.LimitByRowsAndColumns is false, the symbol size is control by the BarcodeData.Bounds and MicroPDF417BarcodeWriteOptions.XModule values used. Otherwise, the value of MicroPDF417BarcodeWriteOptions.SymbolSize will be used.

For more information, refer to Writing Barcodes - Bounds and sXModule.
