Features:
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!
