Barcode Functions (2D) > RenderQRCode

[Professional Edition and above only]

Computes the dimensions of a QR Code barcode.

method void VPE.RenderQRCode(

string Text,

VpeCoord nWidth,

VpeCoord nHeight,

VpeCoord nModuleWidth

)

string Text

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:

// Compute the smallest possible rectangle for a given text

Doc.RenderQRCode("Hello World", 0, 0, 0)

xsize = Doc.nRenderWidth

ysize = Doc.nRenderHeight

// Insert the barcode into the document

Doc.QRCode(1, 1, -xsize, -ysize, "Hello World")
