DrawBarcode1D(Barcode1DWriterType,String,Single,Single,Single,Single,Byte,Byte,Byte,Byte) Method

In This Topic

Draws a required 1D barcode onto the currently selected page of the loaded PDF document according to your preference.

This method uses the CMYK color space for defining the barcode's desired color.

The coordinates and the dimensions of the specified barcode 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 barcode is to be drawn. You can use the GetMeasurementUnit method to determine the currently defined units and you can use the SetMeasurementUnit method to reset the units according to your preference.

Parameters

BarcodeType: A member of the Barcode1DWriterType enumeration. The type of the required barcode.
Data: The data to encode using the required barcode.
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.
DstWidth: The width of the barcode's bounding box, expressed in the current units specified by the SetMeasurementUnit method.
DstHeight: The height of the barcode's bounding box, expressed in the current units specified by the SetMeasurementUnit method.
Cyan: The amount of cyan color to be used for the barcode's resulting color. Use the value between 0 and 255.
Magenta: The amount of magenta to be used for the barcode's resulting color. Use the value between 0 and 255.
Yellow: The amount of yellow to be used for the barcode's resulting color. Use the value between 0 and 255.
Black: The amount of black (key) color to be used for the barcode's resulting color. Use the value between 0 and 255.

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.
