Pano Warp

This plugin lets you perform pixel transformations used in panorama stitching. It can be used for preprocessing single frames and composing a panorama the pedestrian way (e.g. with Photoshop using layers). This is somewhat tedious but sometimes this is the only way to get a decent stitch. Since this preparation is an iterative process, an option is provided to save and load up to five different parameter settings. A simple facility to compensate barrel distortion and vignetting also comes in handy. Pano Warp may also be used for post processing, e.g. to switch between projections or to re-adjust the horizon height. The filter provides facilities to reposition and resize the output image. Grid lines can be displayed both before and after transformation.
