This structure contains PDF417 symbol information.

Member	Description
wEccPerc	Determines the ECC character percentage. This will be used when wEccLevel is BARCODE_PDF417_ECCUSE_PERCENT.
wEccLevel	Determines the ECC level for writing a PDF417 symbol. Possible values are :
	Value	Meaning
	BARCODE_PDF417_ECCLEVEL_0	[0x0001] Use ECC level 0. This uses 2 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_1	[0x0002] Use ECC level 0. This uses 4 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_2	[0x0004] Use ECC level 0. This uses 8 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_3	[0x0008] Use ECC level 0. This uses 16 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_4	[0x0010] Use ECC level 0. This uses 32 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_5	[0x0020] Use ECC level 0. This uses 64 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_6	[0x0040] Use ECC level 0. This uses 128 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_7	[0x0080] Use ECC level 0. This uses 256 code words for error correction.
	BARCODE_PDF417_ECCLEVEL_8	[0x0100] Use ECC level 0. This uses 512 code words for error correction.
	BARCODE_PDF417_ECCUSE_PERCENT	[0x0FFF] Use the percentage to determine the ECC level.
wAspectHeight	The height of the aspect ratio of the symbol.
wAspectWidth	The width of the aspect ratio of the symbol.
wModAspectRatio	Specifies the ratio of the width of the smallest element (wModule) to the height of a row of the PDF417 symbol.
wColumns	Number of columns for writing a PDF417 symbol. When the BARCODE_COLROWASLIMITS flag is set, the function will not use wAspectHeight.
wRows	Number of rows for writing a PDF417 symbol. When the BARCODE_COLROWASLIMITS flag is set, the function will not use wAspectWidth.
wModule	The size of the smallest element in width.
nJustify	Determines the alignment (justification) of the resulting barcode symbols. You can combine values when appropriate, by using a bitwise OR ( \| ). The following are valid values:
	Value	Meaning
	BARCODE_JUSTIFY_RIGHT	[0x1000] Justifies the PDF417 symbol to the right side of the bitmap.
	BARCODE_JUSTIFY_H_CENTER	[0x2000] Justifies the PDF417 symbol in the horizontal center of the bitmap.
	BARCODE_JUSTIFY_BOTTOM	[0x4000] Justifies the PDF417 symbol to the bottom side of the bitmap.
	BARCODE_JUSTIFY_V_CENTER	[0x8000] Justifies the PDF417 symbol in the vertical center of the bitmap.

Comments

pBARCODEWRITEPDF is a pointer to an BARCODEWRITEPDF structure. Where the function parameter type is pBARCODEWRITEPDF, you can declare a BARCODEWRITEPDF variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pBARCODEWRITEPDF variable is necessary only if your program requires a pointer.
