My image viewing app of choice will use EXIF data to automatically rotate images. DOpus will also auto-rotate thumbnails. I love that feature, but occasionally I need to see which images are sideways in order to use them in other applications that don't auto-rotate.
I couldn't figure out an easy way to toggle the setting that makes DOpus auto-rotate thumbnails, so I just changed the setting in preferences and exported that to a file. The idea was that I could create a button to import that preferences file (the one without auto-rotate) when I needed it.
It crashes DOpus every time I use it. If I remove the IMPORTFLAGS=layouts part then it will work as expected.
I have a few questions. 1) Is there an easier way to achieve what I'm looking for? 2) What IMPORTFLAGS argument will import the appropriate setting that I'm trying to change? 3) Can anyone confirm the crashing bug?
I believe nudel just recently filed a bug report on image rotation based upon EXIF meta data. Maybe he'll chime in here to verify whether the problem he saw is the same you're seeing.
So far I cannot reproduce the crash you're seeing but I haven't done much testing with it yet.
The bugs I reported were about a separate issue, I think restricted to the Convert Image tool and how it handled EXIF rotation stuff when it was turned off in other parts of Opus.
I'm not sure if the Prefs import command is correct (it might be, but I never use that command so don't know off the top of my head) but even an incorrect command shouldn't be able to crash Opus so it's worth reporting to GPSoft either way. They may need the prefs file that you're trying to import in case that is tied to the crash.
Using prefs to toggle this flag could be a pain since you then have to maintain two preferences exports. For example, if you change another option in prefs then you have to re-save both your exported prefs files. Not fun!
I think being able to toggle the EXIF rotate option (for thumbnails and I guess the viewer and viewer panel as well) via a command/button would be useful. You could ask GPSoft for such a feature. I know that I would use it sometimes when I'm sending images to other people and want to make sure they'll see them correctly.
I think one of the bug reports I filed was about making it possible to run the Image Convert tool and have it auto-rotate all images and then strip their EXIF tags, so that once you had done it the images will look the right way up in all programs, EXIF support or not. I'm not sure if that works in the current version or not, though. Give it a try. Since JPEG rotation is lossless where possible (unless the image is a strange width/height) you shouldn't usually lose any quality when fixing images like this.
