Can't detect barcodes at the edge of an image

Post by louis_itrellis »

Hello, I've been using Vintasoft's barcode reader SDK (12.4.2.5) for a couple of weeks and it works great, but I found what seems like a bug. If a DataMatrix barcode appears right at the edge of an image (say the left edge) it can't be read. Even with a few pixels of margin/buffer between the edge of the image and the edge of the barcode, the barcode won't be detected.

I can work around this by adding a margin to the test bitmap before executing the reader, then subtracting the margin from the bounding box results, but it would be better if the software did this internally.

Is this a known issue?
