PTGui is a Graphical User Interface for Panorama Tools, Helmut Dersch's versatile panorama stitching software.

PTGui makes it easy to stitch images into high quality panoramas, by providing a visual interface to Panorama Tools.

Panorama Tools is probably the most powerful stitching software available but it can be difficult to use since it requires the user to write command 'scripts'.

PTGui hides all Panorama Tools' scripting commands from the user. PTGui runs on any Windows version.

Here are some key features of "PTGui":

· Create spherical, cylindrical or flat panoramas from any number of source images.
· Supports JPEG, TIFF, PNG and BMP source images.
· Realtime view of warped images and final panorama: you can instantly see what your final panorama will look like, while you edit it.
· 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.
· Reads EXIF information from images produced by digital camera, to determine the lens parameters.
· Multi-threaded design: all image processing is performed in the background.
· Create templates with frequently used settings (you will find some here).
· Lens database for easy storage and retrieval of lens parameters.
· Pattern matching technology enables easy and accurate placement of control points.
· Batch stitcher: prepare any number of panoramas and stitch them later without user intervention.
· Create a printable PhiloSpere of your panorama.
