Barcode orientation

Hi STeven,
Every thing is working real well for decoding the 2d matrix codes. I'm about ready to deploy but I thought I would give my manager a demo on how the system worked. He asked a question if it was important how the parts were oriented in the tray as they are decoded. I indicated yes and the question arose about confirming there orientation.
In the barcode module there is a selection to check all orientations, but seems to only apply to 1d codes. Instead of developing processing to determine proper orientation I was wondering if in the decoding process you already knew the orientation, if so is there a variable you could expose as what orientation was detected? I realize the code could be at a 45 deg angle but would just need to know if it was left, right, top or bottom.
Thanks,
-pete

Pete,
Yes, the orientation is known as part of the decoding process. We've exposed that in a DATAMATRIX_ORIENTATION variable that you can access. Note, this is in degrees with 0 being horizontal right (geometric zero).
Watch out for the 0 to 360 flip when the code is slightly rotated around zero degrees.
STeven.

Hi STeven,
Thanks for the update, works great and has been implemented in the vision decode program.
Thanks,
