Pdf417Params class

PDF417 parameters.

Constructors

Pdf417Params()

Constructor

Pdf417Params.fromJson(Map<String, dynamic> json)

Creates a Pdf417Params instance from a JSON representation.

Properties

aspectRatio ↔ double?

Height/Width ratio of 2D BarCode module.

getter/setter pair

code128Emulation ↔ Code128Emulation?

DEPRECATED: This property is obsolete and will be removed in future releases. See samples of using new parameters on https://releases.aspose.com/barcode/net/release-notes/2023/aspose-barcode-for-net-23-10-release-notes/ Function codeword for Code 128 emulation. Applied for MicroPDF417 only. Ignored for PDF417 and MacroPDF417 barcodes.

getter/setter pair

columns ↔ int?

Columns count.

getter/setter pair

compactionMode ↔ Pdf417CompactionMode?

Pdf417 symbology type of BarCode's compaction mode. Default value: Pdf417CompactionMode.Auto.

getter/setter pair

errorLevel ↔ Pdf417ErrorLevel?

Pdf417 symbology type of BarCode's error correction level ranging from level0 to level8, level0 means no error correction info, level8 means best error correction which means a larger picture.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

isCode128Emulation ↔ bool?

Can be used only with MicroPdf417 and encodes Code 128 emulation modes. Can encode FNC1 in second position modes 908 and 909, also can encode 910 and 911 which just indicate that recognized MicroPdf417 can be interpret as Code 128.

getter/setter pair

isLinked ↔ bool?

Defines linked modes with GS1MicroPdf417, MicroPdf417 and Pdf417 barcodes. With GS1MicroPdf417 symbology encodes 906, 907, 912, 913, 914, 915 “Linked” UCC/EAN-128 modes. With MicroPdf417 and Pdf417 symbologies encodes 918 linkage flag to associated linear component other than an EAN.UCC.

getter/setter pair

isReaderInitialization ↔ bool?

Used to instruct the reader to interpret the data contained within the symbol as programming for reader initialization

getter/setter pair

macroAddressee ↔ String?

Macro Pdf417 barcode addressee name

getter/setter pair

macroCharacters ↔ MacroCharacter?

Macro Characters 05 and 06 values are used to obtain more compact encoding in special modes. Can be used only with MicroPdf417 and encodes 916 and 917 MicroPdf417 modes. Default value: MacroCharacters.None.

getter/setter pair

macroChecksum ↔ int?

Macro Pdf417 barcode checksum. The checksum field contains the value of the 16-bit (2 bytes) CRC checksum using the CCITT-16 polynomial

getter/setter pair

macroECIEncoding ↔ ECIEncodings?

Extended Channel Interpretation Identifiers. Applies for Macro PDF417 text fields.

getter/setter pair

macroFileID ↔ int?

Macro Pdf417 barcode's file ID. Used for MacroPdf417.

getter/setter pair

macroFileName ↔ String?

Macro Pdf417 barcode file name

getter/setter pair

macroFileSize ↔ int?

Macro Pdf417 file size. The file size field contains the size in bytes of the entire source file

getter/setter pair

macroSegmentID ↔ int?

Macro Pdf417 barcode's segment ID, which starts from 0, to MacroSegmentsCount - 1.

getter/setter pair

macroSegmentsCount ↔ int?

Macro Pdf417 barcode segments count.

getter/setter pair

macroSender ↔ String?

Macro Pdf417 barcode sender name

getter/setter pair

macroTimeStamp ↔ DateTime?

Macro Pdf417 barcode time stamp

getter/setter pair

pdf417ECIEncoding ↔ ECIEncodings?

Extended Channel Interpretation Identifiers. It is used to tell the barcode reader details about the used references for encoding the data in the symbol. Current implementation consists all well known charset encodings.

getter/setter pair

pdf417MacroTerminator ↔ Pdf417MacroTerminator?

Used to tell the encoder whether to add Macro PDF417 Terminator (codeword 922) to the segment. Applied only for Macro PDF417.

getter/setter pair

rows ↔ int?

Rows count.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

textEncoding ↔ String?

DEPRECATED: This property is obsolete and will be removed in future releases. Unicode symbols detection and encoding will be processed in Auto mode with Extended Channel Interpretation charset designator. Using of own encodings requires manual CodeText encoding into byte[] array. Sets the encoding of codetext.

getter/setter pair

truncate ↔ bool?

Whether Pdf417 symbology type of BarCode is truncated (to reduce space).

getter/setter pair
