Bug Description
After using the "Lossless JPEG" action to do a lossless autorotate based on exif orientation, there is no way to losslessly save the result. Doing this in IrfanView Thumbnails results in a file size exactly the same as the original (i.e. no loss in quality). With Phatch, I assumed I would not add a Save action after the lossless rotation because this would result in a loss in quality. But running the lossless rotation action by itself results in a file with 0 bytes. So I added a Save metadata action, but that still resulted in a 0 byte file. Adding a Save action gives me an output file that is rotated, but the quality setting in the Save action results is applied to the saved file, with resulting loss.
The attached tar.gz file contains the input jpeg file, the two action files, and the jpeg files that results from the actions.
You should use the action "Save Tags" instead of "Save".
