Rectilinear Panorama is an efficient tool that corrects any geometric image distortions (such as lens, perspective and panorama distortions). Use it to correct barreling, pincushioning, perspective shift, image skewing, panorama distortion, curved horizon and any other distortions that cause curvature of straight lines, changes in shape, size or ratio of dimensions. It works with both panoramic and not panoramic, scanned and digital images.
