Once your image has been acquired and pre-image processing has been performed to recognize the barcode on the image, you can set the following properties:
Checks Before Barcode Recognition
If possible, set the following properties before starting the detection process:
Once these properties are set you are ready to recognize the barcode on the image.
Barcode Xpress detects all barcodes in an image and gives you complete details about them.
If you know where on the image the barcodes reside, setting the Area values to define a smaller rectangular area on your image will speed up processing. By default, these values are set to 0 which tells Barcode Xpress to search the entire image automatically.
Supported Barcodes for Recognition
Barcodes supported for recognition are listed in the Barcode Xpress Overview.
Once the BarcodeTypes property has been determined, use the following methods and properties to recognize the barcode.
Methods
Properties
C# - Minimum C# code to recognize barcodes in an image using Accusoft.BarcodeXpress14.NetCore
// Instantiate BarcodeXpress object.
BarcodeXpress bcx = new BarcodeXpress(".");
// The SetSolutionName and SetSolutionKey methods must be called to distribute the runtime.
bcx.Licensing.SetSolutionName("YourSolutionName");
bcx.Licensing.SetSolutionKey(12345,12345,12345,12345);
// The SetOEMLicenseKey is required if Manually Reported Runtime Licensing is used.
bcx.Licensing.SetOEMLicenseKey("1.0.AStringForOEMLicensing");
// Call Analyze to detect barcodes in the image
// all detected barcodes will be returned to the
// Result object array.
using (Stream bmp = File.OpenRead(imagePath))
{
Result[] results = barcodeXpress.reader.Analyze(bmp);
}
// Get results info.
for (short i = 0; i < results.Length; i++)
{
// Get result for current barcode.
Result curResult = (Result)results.GetValue(i);
// Do something with results.
Console.WriteLine(curResult.BarcodeName);
Console.WriteLine(curResult.BarcodeValue);
}
To obtain the results after analyzing the barcode on an image, see the Access Results topic.
Alternatively, Barcode Xpress can accept an ImGearRasterPage object as a paramater to the Analyze(Object) method.
using (Stream stream = File.OpenRead(imagePath))
{
// Initialize ImageGear Common formats. This will allow you to load a wider variety of images.
ImGearCommonFormats.Initialize();
// Create an ImGearRasterPage object from the file opened.
ImGearRasterPage rasterPage = (ImGearRasterPage)ImGearFileFormats.LoadPage(stream);
var results = bx.reader.Analyze(rasterPage);
// Print out all the results
foreach (var result in results)
Console.WriteLine(result.BarcodeValue);
}
