First time posting, so I hope it’s right to continue this older discussion rather than create a new one as there isn’t a resolution identified as of yet.
It’d be an excellent extension to the framing & mosaic wizard and SGP centering capabilities to introduce a user-defined overscan region offset that would provide expected framing and proper centering on each side of the meridian with this feature enabled. Pinpoint centering with overscan enabled is practically impossible otherwise. My frames benefit from overscan calibration, but until an associated feature is available in SGP, I’ll need to reluctantly continue without overscanning.
The overscan regions on my STF-8300M add 200 rows (right side) and 200 columns (bottom side) to the frame. The first issue I found is that since the framing and mosaic wizard is unaware of this non-imaging region, the “center” isn’t really the center. Currently, the only way to account for it here is to eyeball it. The second and more painful issue comes at a meridian flip: Since the overscan regions have now flipped orientation, the imaging center offset has also flipped orientation, and centering results in an imaging region shifted the twice the size of the overscan regions.
I’ll reiterate what was stated earlier in the discussion: I don’t think the regions need to be automatically detected. Much like the camera data is entered manually, I think it’s perfectly appropriate that the overscan regions could also be manually identified by the user and saved with the profile.
Hope this is helpful feedback. I’d love to see this feature.
