Today we've released version 9.1 of PTGui and PTGui Pro. Several handy new
features have been added in this release:
The new Align to Grid tool makes it easy to
stitch
gigapixel panoramas using a motorized panoramic head.
Also, image alignment for wide angle images (and fisheye images in particular) has been improved.
Further there are lots of usability improvements such as more context menus, a new 'ghost cursor'
and the ability to generate control points in a rectangular area.
For an overview of the new features see What's new in PTGui 9.1.
