Example
Finding all 1D barcodes in a given image and saving their information to a file.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg");
// Specify 1D barcode search types to be Code39 and Code128.
Barcode1DReaderType barcodeType = Barcode1DReaderType.Barcode1DReaderCode39 | Barcode1DReaderType.Barcode1DReaderCode128;
// Start the barcode scanning process. The ExpectedCount parameter is 0, all the barcodes should be retrieved.
gdpictureImaging.Barcode1DReaderDoScan(imageID, Barcode1DReaderScanMode.BestQuality, barcodeType, false, 0);
using (System.IO.StreamWriter file = new System.IO.StreamWriter("barcodes.txt"))
{
int barcodesFound = gdpictureImaging.Barcode1DReaderGetBarcodeCount();
for (int i = 1; i <= barcodesFound; i++)
{
file.WriteLine(gdpictureImaging.Barcode1DReaderGetBarcodeValue(i));
}
}
// Release used resources.
gdpictureImaging.Barcode1DReaderClear();
gdpictureImaging.ReleaseGdPictureImage(imageID);
