Set the BarRatio property to an integer greater than or equal to 3.Set the BarWidth property (Value is expressed in Inches).In our PDF417 implementation the BarHeight property is calculated as BarWidth * BarRatio.ISO/IEC standards recommend a minimum error correction level of 2. Set the Pdf417ErrorCorrectionLevel property.Auto: It switches between Text, Binary and Numeric modes in order to minimize the number of codewords to be encoded.Numeric: It allows efficient encoding of numeric data strings.This includes all ASCII characters value from 0 to 127 inclusive and provides for international character set support. Binary: It allows encoding all 256 possible 8-bit byte values.values from 32 to 126 inclusive in accordance with ISO/IEC 646, as well as selected control characters such as TAB (horizontal tab ASCII 9), LF (NL line feed, new line ASCII 10) and CR (carriage return ASCII 13). Text: It allows encoding all printable ASCII characters, i.e.Set the Pdf417CompactionType property to:.Set the Symbology property to CompactPdf417.In order to get a Compact PDF417 barcode image, please follow these steps: Note: Please refer to the Class Reference documentation for more information about the properties and methods stated in this document. The name Compact PDF417 is preferred to avoid confusion with the more general use of the term 'truncated'. NOTE: In the original AIM USA (1994) and AIM Europe (1994) PDF417 specifications, the term Truncated PDF417 has been used in a technically synonymous manner. This overhead reduction version is called Compact PDF417, which is fully decoder compatible with standard PDF417. This procedure reduces the non-data overhead from 4 codewords per row to 2 codewords per row, with some trade-off in decode performance and robustness, or the ability to withstand noise, damage, degradation, dust etc. an office), the right row indicators, that PDF417 Symbols feature, may be omitted and the stop pattern may be reduced to one module width bar. In an environment where label damage is unlikely (e.g. However, Compact PDF417 may be used where space considerations are a primary concern and symbol damage is unlikely.
