Parameters

Data

The data to encode using the required barcode symbol.

EncodingMode

A member of the BarcodePDF417EncodingMode enumeration. The barcode encoding mode.

You can use the BarcodePDF417EncodingMode.BarcodePDF417EncodingModeUndefined to let the engine analyze the input and to select the most appropriate encoding mode.

ErrorCorrectionLevel

A member of the BarcodePDF417ErrorCorrectionLevel enumeration. The error correction level.

You can use the BarcodePDF417ErrorCorrectionLevel.BarcodePDF417ErrorCorrectionLevelAuto to let the engine automatically determine the required level.

Rows

Specifies the number of rows constituting the barcode symbol.

A PDF417 symbol must have at least 3 rows and no more than 90. It is recommended to use 0 for automatic computation.

Cols

Specifies the number of columns constituting the barcode symbol.

A column refers to the set of codewords vertically. A PDF41 symbol may have 1 to 30 columns. It is recommended to use 0 for automatic computation.

ModuleWidth

The width of a module, in points.

Module is the smallest unit of a PDF417 symbol. The width of a module (width of the narrowest bar) is commonly referred as X dimension of the symbol, for more details on this please read the Remarks section below.

RowHeight

The height of each row, in points.

For better decodability, height should be no less than 2, for more details on this please read the Remarks section below.

DstX

The horizontal (X) coordinate of the destination point, expressed in the current units specified by the SetMeasurementUnit method with respect to the defined origin, related to the currently selected page.

DstY

The vertical (Y) coordinate of the destination point, expressed in the current units specified by the SetMeasurementUnit method with respect to the defined origin, related to the currently selected page.

Red

The amount of red color to be used for the symbol's resulting color. Use the value between 0 and 255.

Green

The amount of green color to be used for the symbol's resulting color. Use the value between 0 and 255.

Blue

The amount of blue color to be used for the symbol's resulting color. Use the value between 0 and 255.

Return Value

Just to remind you that the PDF417 barcode is usually printed at an X to Y ratio of 1:2 to 1:5, with 1:3 being the most popular. By lowering the ratio, a significant amount of space can be saved; however, some scanners cannot read X to Y ratios of less than 1:3.

Likewise, just to remind you that 1 point is equivalent to 1/72 of an inch.

This method requires the Barcode Reading & Writing component to run.
