Not able to read QR barcode

Aspose.BarCode Product Family

I am facing issue while reading the QR barcode with following code.

using (Aspose.BarCodeRecognition.BarCodeReader bcr = new Aspose.BarCodeRecognition.BarCodeReader(filename, BarCodeReadType.QR))
{
while (bcr.Read() == true)
{
//some code
}
}

The same images are getting recognized with below code.
using (Aspose.BarCode.BarCodeReader bcr = new Aspose.BarCode.BarCodeReader((Bitmap)img))
{
bcr.BarCodeReadType = (Aspose.BarCode.BarCodeReadType)((long)symbologies);
bcr.Orientation = (Aspose.BarCode.Orientations)((int)orientations);
bcr.ScanStep = scanStep;

Aspose.BarCode.BarCodeInfo[] bars = bcr.Read();
}

I am using the first code to implement the TimeOut, which is not available with the second code. But first code is not able to read the images having QR barcode.
I am attaching 5 images, none of them are getting recognized.

Referring to the other posts on this site, I also used latest build 5.8.0.0. That is also not working.

Thanks
Sachin.

Imran,

One more thing I would like to mention. When I changed the reference of my project to latest 5.8.0.0 DLL, the component listed below are no longer available. 

Aspose.BarCode.BarCodeReader

Aspose.BarCode.Orientation

Aspose.BarCode.BarCodeReadType

Aspose.BarCode.BarCodeInfo

 
Thanks
Sachin

Hi Sachin,

Thank you for these details. I would like to update you that there are two separate libraries one for barcode generation and another for the barcode recognition part. These classes/enums are part of recognition part. Its library name is Aspose.BarCodeRecognition.dll. BarCodeInfo class has been obsoleted. Please find the correct namespaces below:

Aspose.BarCodeRecognition.BarCodeReader

Aspose.BarCodeRecognition.RecognitionHints.Orientation

Aspose.BarCodeRecognition.BarCodeReadType

Please do let me know in case of any confusion or questions.
