Only one barcode is detected

Post by BenV » Mon Dec 27, 2010 3:38 pm

Hello there

Please see the attached image. When I open this image in the 1D Barcode Recognition sample only one barcode, the one on the bottom, is detected. When I open the same image, but the barcode at the bottom is cut of, it does recognize the first barcode.

I'm actually trying to aquire an image by a TWAIN device and imediatly detect the two barcodes printed on it. The paper I'm scanning looks like the one in attached but it's not the same. I just discovered that when I open an already scanned paper (with the CreateGdPictureImageFromFile() method), the barcode detection does work and fails when the image is aquired by TWAIN.

Hello Ben,

We are currently working on some improvement of the barcode reader. I can say that today your image is correctly recognized by our beta version.
So, this problem will be fixed in GdPicture.NET 7.3.2.

Kind regards,
