[![][1] We are pleased to announce the release of Aspose.Barcode for .NET 7.5.0. This release supports encoding and decoding GS1QR barcodes, and specifying manual hints and multiple recognition areas to speed up the recognition process.

Speed up barcode recognition process using manual hints

Aspose.Barcode for .NET allows you to specify manual hints and speed up recognition process. BarCodeReader.ManualHints property can be set to appropriate ManualHint enumeration value e.g.

 Stopwatch watch = new Stopwatch();
string filename = @"Barcode.jpg";
using (BarCodeReader reader = new BarCodeReader(filename, BarCodeReadType.DataMatrix))
{
	watch.Start();
	reader.RecognitionMode = RecognitionMode.ManualHints;
	reader.ManualHints = ManualHint.MedianSmoothing;

	while (reader.Read())
	{
		Console.WriteLine(reader.GetReadType() + ": " + reader.GetCodeText());
	}
	watch.Stop();
	Console.WriteLine("Time: " + watch.ElapsedMilliseconds + "ms.");
}

Read barcodes from multiple regions

Aspose.Barcode for .NET allows you to read barcodes from certain regions of the images. A new constructor of BarCodeReader class has been introduced with accepts a list of rectangles to read barcodes from those rectangular areas only e.g.

 Bitmap bitmap = new Bitmap("Three_Barcodes.png");

Rectangle[] areas = new Rectangle[3];
areas[0] = new Rectangle (50, 50, 300, 300);
areas[1] = new Rectangle (400, 40, 350, 350);
areas[2] = new Rectangle (40, 500, 700, 150);

using (BarCodeReader reader = new BarCodeReader(bitmap, areas, BarCodeReadType.AllSupportedTypes))
{
	while (reader.Read())
	{
		Console.WriteLine(reader.GetReadType() + ": " + reader.GetCodeText());
	}
}
