GetDefaultOptions Method (original) (raw)
Summary
Gets the default write options for a specified symbology.
Syntax
C#
Objective-C
C++/CLI
Java
Python
- (LTBarcodeWriteOptions *)defaultOptionsForSymbology:(LTBarcodeSymbology)symbology; public BarcodeWriteOptions getDefaultOptions(BarcodeSymbology symbology) Parameters
symbology
An BarcodeSymbology enumeration member that specifies the barcode symbology (or type) to get its options.
Return Value
The BarcodeWriteOptions derived object used by this BarcodeWriter as the default write options to use when writing barcodes of the type specified in symbology.
Example
This example shows how to get the default options used when writing standard linear 1D barcodes (UPC-A, UPC-E, etc) and then changes them before writing a barcode
