GdPicture Imaging Forums

Attached to this post there are 2 JPGs, from which I can't read the PDF417 barcode.
One is a Color 300dpi image, and the other is a Grayscale 300 dpi
Many, many things I tried, but cant't recognize the barcode.
I'm just using the provided demo inside the folder: "...\GdPicture.NET 10\Samples\AnyCPU\vb.net\Barcode Recognition" Please tell me some hints...

Hi,

The reason is simple: The image was scanned with really low sampling: it has a dpi of 72.
For proper detection, images need to be sampled at 200-300 dpi to provide no overlap or mis-shaped barcodes.

Best,
Sami
