(TBarcode2D_PDF417, TBarcode2D_CCC)
Specifies whether the PDF417 barcode symbol is generated in Compact PDF417 format, or the CC-C 2D component of an EAN.UCC composite barcode symbol is generated in Compact format.
property Compact: Boolean;
In an environment where space considerations are a primary concern and symbol damage is unlikely (e.g. an office), the right row indicators of a PDF417 symbol may be omitted and the stop pattern may be reduced to one module width bar. This reduction version is called Compact PDF417, which is fully decoder compatible with standard PDF417. The property specifiies whether the PDF417 barcode symbol is generated in Compact PDF417 format. See diagram:
For the CC-C 2D component of an EAN.UCC composite barcode symbol, it's a variant of PDF417 symbol and similar with the PDF417 barcode symbol, the property specifies whether its right row indicators should be omitted and its stop pattern should be reduced to one module width bar. See diagram:
Note, the Compact PDF417 was referred as Truncated PDF417 in previous standard.
