A plug-in that takes three control points on a layer and then distorts the layer (by scaling, translating, rotating, and stretching) so that those points end up on three other identified control points would be very useful. For example, if you wanted to combine two images shot at different exposures to increase the dynamic range and the shots were handheld, you would need to do some or all of these manipulations in order to make the images line up as well as possible. The first three portions of this function, scaling, translating, and rotating, can all be done with existing GIMP plug-ins, and I have written a script-fu to do just that. But the stretching function that is required to help account for variations in lens distortion due to slightly different image centers (from hand-holding) is not possible. Such a plug-in would ideally work with a minimum of two points (in which case the stretching is not performed) and could theoretically work with more than three points to allow for even better control of the mapping. Having live feedback of the manipulation, either through a preview window or on the image window), would greatly assist the user with determining how many points are required to adequately perform the manipulation. Having the ability to place the control points and then tweak their position by dragging them while observing the live feedback would be ideal. What are everyone's thoughts on this? Is it worth initiating an enhancement request in Bugzilla? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
