Property: DefaultEncodeMode

(TBarcode2D_MicroPDF417)

Specifies the initial compaction mode for a MicroPDF417 barcode symbol.

Syntax:

type

{ Defined in the pMicroPDF417 unit }

TMicroPDF417_EncodeMode = (emText, emByte, emNumeric, emNull);

property DefaultEncodeMode: TMicroPDF417_EncodeMode;

Description:

The property specifies the initial compaction mode for a MicroPDF417 barcode symbol. In the specification of MicroPDF417, the initial compaction mode in effect at the start of each symbol shall always be Byte compaction mode, but some readers use the Text compaction mode (Alpha sub-mode) as the initial compaction mode. The property should be set to match your reader. If you don't known the initial compaction mode used by your reader, please set the property value to emNull, or you can change the Options property to include the "poMicroPDF417Explicit901" value, in order to explicitly insert a mode latch to Byte compaction mode into beginning of symbol data.

The property can be one of these values (defined in the pMicroPDF417 unit).

• emText: Indicates the initial compaction mode to Text compaction mode. You can use the DefaultTextEncodeMode property to specify the Text compaction sub-mode.
• emNumeric: Indicates the initial compaction mode to Numeric compaction mode.
• emByte: Indicates the initial compaction mode to Byte compaction mode.
• emNull: The appropriate initial compaction mode will be introduced by an explicit mode latch depending on the barcode text.
