Background transparency #243
Description
Is your feature request related to a problem? Please describe.
I would like to be able to eliminate the transparency and use a black background. Seeing other files listed behind an image takes away from the image viewing experience. All emphasis should be on the photo, not other NextCloud files.
Describe the solution you'd like
I would like a configuration option to set the viewer transparency percentage. If that's not possible, I'd like to just have a black background instead of a transparent one.
Describe alternatives you've considered
The only alternative I have found is to disable this viewer and use the gallery viewer for photos. This might not be an option in the future depending on if the gallery app is changed to use this viewer instead of it's own.

Hey! Thanks for your report! We aim to simplicity and don't want to add options for such variations of the software. I feel like the current background is pretty ok to me, but maybe you think we should darken it a bit.
Can you provide an example of opacity that would fit your need?

Currently it’s at
rgba(0,0,0,0.92), how about we try withrgba(0,0,0,0.97)for some time?It’s much darker, but still gives a slight bit of context.

Why does it have to be transparent at all? The only thing that should be visible is the photo/video/etc being viewed. Everything else is a distraction.

Maybe the background should be 100% black when the photo is viewed full screen and the transparency could be kept when not in full screen mode... just an idea.
jancborchardt commentedon Sep 14, 2019
Yeah, I'm also fine with it being fully black.
@skjnldsv @juliushaertl I guess having it slightly transparent is another thing that is special for the first run wizard. And there it should also be more transparent than .92 opacity.

Didn't we have 0.97 in the beginning and we decreased it because the context of the files app was totally missing?
skjnldsv commentedon Sep 14, 2019
It's the other way around, it was too light, and we increased it twice: nextcloud-libraries/nextcloud-vue#300
.7=>.85=>.92jancborchardt commentedon Sep 14, 2019
Yup, most of the changes are because we used the viewer for the first run wizard initially, and only then for pictures.
So they actually have slightly different requirements. :)
skjnldsv commentedon Sep 14, 2019
@jancborchardt then I'll let you decide :)
jancborchardt commentedon Sep 15, 2019
Hehe, then let’s do:
From there we can still see if we need to adjust anything. But the important thing is we separate these 2 distinct cases.

What would be the default modal component value?
jancborchardt commentedon Sep 16, 2019
Let’s use the same as first run wizard for now? We could maybe also then move the first run wizard / default value down again to a previous value of .85 or .7?
And then we have special cases for:

Btw https://github.com/nextcloud/nextcloud-vue/blob/ccd42cc97c21dfa9d9d8f4ac0363b8833c26b7df/src/components/Modal/Modal.vue#L489
What shall we do? It isn't that bad in the end?

Thank you for the suggestion and for taking the time to report it.
The Nextcloud Viewer is no longer developed as a standalone app. Its code has moved to the
@nextcloud/viewerlibrary, which is now maintained at https://github.com/nextcloud-libraries/nextcloud-viewer. Because of this, we will not add any further enhancements to this repository and are closing open feature requests here.If you are still interested in this feature, please open a new feature request in the library repository:
