Pano Warp perform pixel transformations used in panorama stitching.
EditByBSEditor: This plugin lets you perform pixel transformations used in Panorama stitching. I am well aware of some excellent panorama stitching tools out there which do it all automatically without you having to bother much. These work fine if you take your pictures with a tripod and make sure the horizon is in the Middle, but if you dont, you can have a real hard time. There is also the problem with curved lines in architecture photography. Check out the examples below and youll see what I mean.

My plugin will give you full control, but that also means you have to play around a bit. You can use it for preprocessing single frames and compose your panorama the pedestrian way (e.g. with Photoshop using layers). This is somewhat tedious but I occasionally encounter situations where this is the only way I can get a decent stitch. Since this preparation is an iterative process, I found it useful to provide an option to save and load up to five different parameter settings. A simple facility to compensate barrel distortion and vignetting also comes in handy.

You might also want to use Pano Warp for post processing, e.g. switch Between projections or re-adjust the horizon height. The Filter lets you reposition and resize the output image. Grid lines can be displayed both before and after transformation. you can free download Pano Warp 4.2 now.
