Cannot recognize some datamatrix codes
Posted: Wed Nov 16, 2011 4:14 am
Hi,
I already opened a ticket n. 15605 about this issue with a few datamatrix codes. I attach the files here as well, as usually you are quite fast answering the forums.
Most of these datamatrix cannot be recognized at 200 DPI, the reverse one not even at 600 DPI. With other free tools, such datamatrix scanner on Android smartphone there's no problem with any of these.
Can you please help us to solve this problem?
Thanks and regards

In addition I have a question, is it possible to render just a portion of a PDF file to a GdPic image? This way I could keep high DPIs without loading in memory the whole page, which would cause memory problems in most PCs.

Just tried the samples images found at "C:\Program Files (x86)\GdPicture.NET 8\Images\barcodes\DataMatrix", and cannot recognize 6.jpg, using the "Csharp-Barcode Recognition - DataMatrix" sample project.
