Barcode Orientation

Post by moakley » Sun Aug 10, 2014 8:26 pm

Is there a way to limit the orientation of barcodes read from a PDF to just horizontal, or just vertical?

Hi,

I am not sure I understand the question: Do you want to be able to draw vertical and horizontal 1d barcodes as opposed to just horizontal?
If so, all you need to do is make a call to AddRotationAt before the drawing operation: oGdPicturePDF.AddRotationAt(90, 0, 0)

Best,
Sami

Talking about reading barcodes and limiting those barcodes read to just horizontal or vertical.

Hi,

No there is no such thing. As a matter of a fact, it would not make sense, because you would have to start tracing the barcode to determine its angle, meaning that you have already started the processing of recognizing it.

You can easily neglect all barcodes that are not at 0 or 180 angles (plus some small range for error margin).

Best,
Sami
