reading some of the JPEG related articles here I wondered whether GIMP or GEGL can do lossless rotation and cropping on JPEG images. Can you tell me more about it?
For rotation, that would only work on images with dimensions that are a multiple of 8. For cropping, that only works if you crop on 8-pixel boundaries from the origin corner.
Otherwise, this also assumes that JPEG is an "editable format", while the recent kerfuffle around the Export function has demonstrated that it is not, in the current vision.
Yes, 'Export vs. Save' was a long discussion and I don't want to boost it again. Although it takes a little getting used to I can live with the new behaviour. Despite of that I sometimes wondered in the past whether GIMP will introduce new compression artifacts if I rotated or cropped an existing JPEG image (yes, there are some cameras where saving in JPEG of sufficient quality is the best choice. Shall we not use them anymore?).
