PTGui Pro is panoramic stitching program for Mac OSX. Originally developed as a Graphical User Interface for Panorama Tools (hence the name), PTGui Pro is a full featured photo stitching application. You can use PTGui Pro to stitch any number of photos into a panoramic image, can stitch multiple rows of images, and can create 360 degree cylindrical panoramas, flat partial panoramas and even spherical 360x180 degree panoramas. PTGui Pro stitches most panoramas fully automatically, but at the same time provides full manual control over every single parameter. This enables stitching of 'difficult' scenes, where other programs fail.
