VFOV bug in Version 13.3

[Tom Sharpless]

PTGui 13.3 on Windows 11, stitching a set of photos less than 180 degrees high:

cannot set the vertical panorama axis to 180.

The slider stops at 179 --  this leads to aspect ratio > 2:1

If type in 180, get 18.  Can type in 179.9999 and get full aspect ratio.

Tom, I am unable to reproduce this error.  Can you supply a project file (no images required) that demonstrates the fault condition?

Hi Tom,

This is the expected behavior for projections with a limited vertical
field of view. For example cylindrical, where the vfov must be strictly
less than 180 degrees.

Does that explain what you see?

Kind regards,

[sound of one hand clapping]
Yes, of course, I had the projection set to cylindrical! (rarely do that)
