Please add lossless Operations to Context Menu

[mpy]

Hi & thanks a lot for XnView/XnViewMP!

What I really miss in XnVIewMP is the possibility to invoke the lossless operations within the context menu of an image.
It's annoying that you have to use the Tools menu in the menu bar.

One might argue, that also the other Tools are not included in the context menu, but this lossless context entry is there in XnView (non-MP version)

Thanks for taking that into consideration.

Well, I certainly understand what you want. However, I think that the right-click menu is a little bit cluttered and, also, today there are other formats on which 'loseless rotate' doesn't apply. All RAW formats come in mind, for example.

But perhaps I would support your suggestion if you couldn't have the possibility to assign/change the shortcuts for each command, which is a faster way to do it (See Tools | Settings | Interface | Shortcuts) than via menu (both right-click and main menu). There are already assigned some shortcuts for these commands so I think that you should better use Ctrl+Shift+L and Ctrl+Shift+R or, if you want, you can change them.

@m.Th.: I appreciate your answer and agree with you largely.

Is it possible to lossless rotate RAW formats? If so, what about a "lossless rotate" independent of the file format? Would IMHO be very user-friendly.

Indeed, so perhaps a more brave suggestion would be:
- context menu configurable by the user
- context menu dependent of the file type

have the possibility to assign/change the shortcuts for each command

Definitively correct, thanks for the hint!

NO, it isn't possible to rotate RAW formats. I said that 'loseless rotate' doesn't apply (see my quoted part above). IOW, it is meaningless on some formats, especially on RAW formats because these are proprietary (they are usually hacked/reverse engineered), and not only this - the RAW formats must be processed through a complicated pipeline (demosaicing etc.) in order to get the image and, also, there is NO known code to write the RAW formats (in order put back the rotated image). However, one can fake this by changing the EXIF orientation flag but now I cannot think why this would be useful...

Hum....

A run-time/user configurable menu It is certainly doable...

However, I don't know if it is worth the hassle to do it because it needs a tab similar with the Settings | Interface | Toolbar and a persistence (In/Out) engine to save the settings.

I would lightly support this if it is easy to do it - but it seems that it is not because the program has also some dynamic data in that popup menu like Categories tree etc.

A popup menu / file type I think that isn't feasible because, in fact, only the JPG will be 'different'.
