Parameters

ImageID: GdPicture image identifier.
BarcodeType: A member of the Barcode1DWriterType enumeration.
Data: The data of the barcode to encode.
DstLeft: Left pixel destination of to top-left corner of bounding box the barcode.
DstTop: Top pixel destination of to top-left corner of bounding box of the barcode.
DstWidth: Width of the bounding box of the barcode.
DstHeight: Height of the bounding box of the barcode.
FillColor: Color of the barcode. A suitable color value can be obtained by using the ARGB() method.
Alignment: A member of the BarcodeAlign enumeration.

Return Value

A member of the GdPictureStatus enumeration.

Example

Rendering a centered 1D barcode into a new image and saving the result into a png file.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    // String with numbers, which have to be encoded into a barcode.
    string data = "123456";
 
    int dstLeft = 10;
    int dstTop = 10;
    int dstWidth = 300; // Barcode width
    int dstHeight = 80; // Barcode height
 
    // Select the 1D barcode type.
    Barcode1DWriterType barcodeType = Barcode1DWriterType.Barcode1DWriterStandard2of5;
 
    int imageID = gdpictureImaging.CreateNewGdPictureImage(20 + dstWidth, 20 + dstHeight, 32, Color.White);
    gdpictureImaging.Barcode1DWrite(imageID, barcodeType, data, dstLeft, dstTop, dstWidth, dstHeight, gdpictureImaging.ARGB(0, 0, 0), BarcodeAlign.BarcodeAlignCenter);
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
