PTGui is panoramic stitching software for Windows and Mac OSX. Originally developed as a Graphical User Interface for Panorama Tools (hence the name), PTGui now is a full featured photo stitching application. Use PTGui to stitch any number of photos into a panoramic image. Some benefits of PTGui, when compared to other stitching software: PTGui can stitch multiple rows of images Create 360 degree cylindrical panoramas, 'flat' partial panoramas and even spherical 360x180 degree panoramas No need to keep the camera level: PTGui can stitch rotated and tilted images Virtually unlimited output size: create Gigapixel panoramas from hundreds of images! Layered output allows full control over the final stitched result PTGui 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.
