Parameters

Data: The data of the barcode to encode.
EncodingMode: A member of the BarcodePDF417EncodingMode enumeration. The encoding mode.
ErrorCorrectionLevel: A member of the BarcodePDF417ErrorCorrectionLevel enumeration. The error correction level.
Rows: Specifies the number of rows constituting the barcode. Use 0 for automatic computation (recommended) or a value in the range [3 - 90].
Cols: Specifies the number of columns constituting the barcode. Use 0 for automatic computation (recommended) or a value in the range [3 - 30].
QuietZone: The number of modules composing the quiet zone. The quiet zone defines the margin around the barcode. A value superior or equal to 4 is highly suggested.
ModuleWidth: The width of each module, in pixels. A value superior or equal to 4 is recommended.
RowHeight: The height of each row, in pixels. A value superior or equal to 10 is recommended.
Width: Output parameter. The width, in pixels, required to render the PDF417 barcode.
Height: Output parameter. The height, in pixels, required to render the PDF417 barcode.

Return Value

A member of the GdPictureStatus enumeration.

Rendering a PDF417 barcode into a new image and saving the result into a png file.
