QR code parameters



I'm working on adding some QR codes to a label. The ^BQ command seems to get a lot of its configuration from the ^FD command, which seems a little unique. After trying a few different settings, it appears to me that only a few of the "formal" ^BQ parameters are used:


  1. Orientation: ignored?
  2. Model: not ignored
  3. Magnification: not ignored
  4. Error correction level: ignored, even if no value specified in ^FD?
  5. Mask: ignored?


Can you verify whether or not parameters 1, 4 and 5 are always ignored? If not, can you provide a small example where they are not ignored?
