DrawBarcodeDataMatrix(String,BarcodeDataMatrixEncodingMode,BarcodeDataMatrixVersion,Int32,Single,Single,GdPictureColor) Method

In This Topic

Draws a required DataMatrix barcode onto the currently selected page of the loaded PDF document according to your preference.

This method uses the RGB color space internally when manipulating with the barcode symbol's fill color you have specified.

The coordinates and the dimensions of the DataMatrix barcode symbol need to be set in the current units with respect to the currently located origin defined in the PDF document, related to the actual page, where the symbol is to be drawn. You can use the GdPicturePDF.GetMeasurementUnit method to determine the currently defined units and you can use the GdPicturePDF.SetMeasurementUnit method to reset the units according to your preference.

Parameters

Data: The data to encode using the required barcode symbol.
EncodingMode: A member of the BarcodeDataMatrixEncodingMode enumeration. The DataMatrix barcode high level encoding mode.
Version: A member of the BarcodeDataMatrixVersion enumeration. The version of the DataMatrix barcode.
You can use the BarcodeDataMatrixVersion.BarcodeDataMatrixVersionAuto to let the engine decide the minimum version required to encode all specified data.
ModuleSize: The size of each module within the drawn symbol, in points.
The module is the smallest cell in the DataMatrix barcode. The module size has to be made out of at least 2×2 printed dots for bigger reliability, therefore the recommended value for this parameter is 4 and greater.
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.
FillColor: A color object that defines the color to be used for drawing a required barcode symbol.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks

This method is only allowed for use with non-encrypted documents.

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.
