I chose OPus to handle jpeg files, when double clicking on a
jpeg file opus viewer oppens - thats ok. But i cannot scroll
forward or backward between pictures with mouse wheel or
clicking the picture - it dont work either if i ckick on the
small arrows in the opus viewer window. Whats wrong?
Looks like that is also why Next/Prev wasn't working. Opus only seems to genereate the next/prev lists if the internal picture viewer was turned on in Prefs. If the Opus viewer is launched, but via filetypes rather than that setting, then it acts as if an external program launched it and doesn't generate the Next/Prev list.
You can only have one thing working or the other at the moment, unless you want to unregister the image filetypes that you do want Opus to handle, and then tell Opus to use the internal viewer only for unregistered types, leaving TIF registered to the MS viewer.
how do i do what you suggest - regarding registration ? so that it works ? I only want tiffs to be handled by default windows viewer (because tiffs can be multi paged - and opus cant show more that the first page) the rest i want handled by opus
I've mentioned it to GPSoft and it sounds like the viewer should be able to generate the file list when launched the other way, but they haven't said when the improvement will be done. I think they're very busy getting things wrapped up for the next release so this may not make it in the very next version. It's something I want too, though, so I'll keep bugging them.
For what it's worth, I'm part of the way through making a multi-page TIFF plugin but I don't know when it will be ready as a bunch of other plugin work has higher priority at the moment and I'm doing it all in my spare time.
The more I think about it the more I think my idea isn't a great one, but if you delete the filetypes (using the Opus filetype editor) for the images that you do want shown in Opus, then set Opus to only use the internal viewer for recognised images which don't have registered filetypes, then you should get what you want.
Of course, you'll also lose the ability to double-click those image files outside of Opus, and they'll have generic icons and so on... It's not really a good idea. For now you are probably better off living with either the Opus viewer not having a next/prev list, or viewing TIFF in the Opus viewer.
An alternative solution is to let the Opus viewer handle all double-clicked image files and then create a toolbar button or hotkey which opens the selected files using the Windows viewer. Then you can use that to view TIFF files, although they'll still open in the Opus viewer if you double-click them.
