Barcode Functions (2D) > VpeRenderPDF417

[Professional Edition and above only]

Computes the dimensions of a PDF417 barcode.

void VpeRenderPDF417(

VpeHandle hDoc,

LPCTSTR lpszText,

VpeCoord nWidth,

VpeCoord nHeight,

VpeCoord nModuleWidth

)

VpeHandle hDoc

Document Handle

LPCTSTR lpszText

the text of the barcode

VpeCoord nWidth, nHeight

With these two parameters you can specify a maximum size the barcode can have.

The following rules apply:

•nWidth and nHeight is specified: in this case the maximum rectangle of the barcode will be computed, which will fit into the given rectangle.

•Only nWidth is specified, nHeight is zero: In this case nHeight is computed (nWidth is also computed, i.e. adjusted).

•Only nHeight is specified, nWidth is zero: In this case nWidth is computed (nHeight is also computed, i.e. adjusted).

•nWidth and nHeight are zero: in this case the smallest possible rectangle is computed

VpeCoord nModuleWidth

If this parameter is zero, VPE will choose itself an optimum barcode module width. If it is non-zero, you can specify the width of a barcode module.

Example:

szStr =

"01\t05\t{)>\t82\tWSP3.5.1DE\r"

"02\t23112001\t1Z32630V6851146547\t08\tM\t9838571153\t3"

"\t1.5\tKgs\t1.5\t\tP/P\t0.00\t\t\t\t\tDE\t\t\t\r"

"04\tSH\tX-LOGISTIK GMBH\tWALLENHORST\t\t49134\tDE\t32630V"

"\tC/O INTERTRADE AG\t\t\t\tHERR ERNST LEMKE\t+495407-834343\t"

"\tAM OHLENBERG 14\t\r"

"04\tST\tIDEAL SOFTWARE GMBH\tNEUSS\t\t41464\tDE\t"

"\tERFTSTR. 102A\t\t\t\tMR. XXX\t\t\t\t\r"

"99\r";

// Compute the smallest possible rectangle for a given text

VpeRenderPDF417(hDoc, szStr, 0, 0, 0)

xsize = VpeGet(hDoc, VRENDERWIDTH)

ysize = VpeGet(hDoc, VRENDERHEIGHT)

// Insert the barcode into the document

VpePDF417(hDoc, 1, 1, -xsize, -ysize, szStr)
