PTGui 8.2.1

PTGui is very interesting panoramic stitching software for Windows and Mac OSX.

Use PTGui to stitch any number of photos into a panoramic image. Some benefits of PTGui, when compared to other stitching software.

Main features:
- Create spherical, cylindrical or flat panoramas from any number of source images.
- Fully automated: create single row, multiple row or fully spherical panoramas in just a few mouse clicks.
- Realtime preview of final panorama: you can instantly see what your final panorama will look like.
- Panorama editor for visual and interactive parameter editing: Move your images with the mouse to change yaw, roll and pitch parameters. Perspective is corrected in real time.
- PTGui can stitch HUGE panoramas! Stitching 200 images into a multiple gigapixel panorama is no problem.

Version restrictions:
- Stitched panoramas will have a visible watermark.

Enhancements
- Help file updated.
