PTGui

PTGui is a panorama photo stitching program for Windows and macOS developed by New House Internet Services BV. PTGui was created as a GUI frontend to Helmut Dersch's Panorama Tools. It features its own stitching and blending engine^[2] along with compatibility to Panorama Tools. PTGui supports telephoto, normal, wide angle and fisheye lenses^[3] to create partial cylindrical up to full spherical panoramas. PTGui can handle multiple rows of images.^[4]
