PTAssembler is a (Windows) panoramic image stitching software program.
BSEditor: PTAssembler is a (Windows) panoramic image stitching software program, able to Create single and multi-row panoramic and high-resolution mosaic images. As a software developer and photographer, I have been using PTAssembler for several years to create my own high resolution images. PTAssembler is more complex than many popular automagic stitching programs. But, it is much more powerful and flexible, giving the photographer unparalleled control over the final result. The automagic programs often deliver pretty good results. With PTAssembler, perfectly stitched panoramas can be created every time.

Stitching images together with PTAssembler gives you complete control over the process. You can choose to auto-create a stitched image with little or no manual intervention. Alternatively, you can choose a more manual approach to ensure the absolute highest quality result. And, the two approaches can be also be combined.

PTAssembler can output a final image in JPEG, TIFF, PSD, PSB format, or layered image file(s) (PSD, PSB or multiple TIFF files) that allows the user to perform the final blending Between adjacent images manually.
