No. They would not make much sense in the GIMP. Once an image is open, the GIMP doesn't 'know' were it came from - but for it's name and save options. For this to work, the transform tools would have to be 'jpeg aware' - moreover, no other image editing of any kind could be done besides the rotate or flip, before the image is saved back again. In short: you'd better doing these trasnforms with another program that doesn't do general editing of a image. Ok - I can think of one way of this being feasible - when the structure for the macro recorder is in place, or when an API for the undo steps is in place, the Jpeg filter could check, on save, if a) The image was loaded from a jpeg, and the original file is still available b) The only operations performed on the image were images that can be performed in lossless way And them it would: c) Discard the Gimp image data, and perform the transform by itself on the orginal file. --That means, that the jpeg plug-in would do the job, not the GIMP. It would be feasible, but I do not see it making much sense, and would be a terrible hack. _______________________________________________ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
