Wallpaper in desktop. Is it a bug?
Hello world, I have a (dumb) question about wallpapers in LLx.
When I set it for system I can crop and zoom it to choose visible area (I guess it’s using the system wallpaper app and I’m fine with that).
But when i try to set a desktop wallpaper here is what happened :
– if I’m using the picture “as this” it is displayed at full scale : it’s centered and cropped to match my screen resolution (I guess)
– with the same picture (with resolution > to my screen resolution) if I try to crop it before setting it then it becomes really small.
To give an example : picture size is 3120×4160, my screen is 2560×1440 and when I select it on LLx desktop settings it shows : 780×1040 (before cropping).
If applied as this I think the initial picture size is kept. But when cropped the cropped size is the one used instead of the real cropped size.
And I don’t know where this 780×1040 size comes from.
Is it a bug? I apologize if it has already been reported.
Enjoy !

Android sucks at handling large images. In most situations they have to be downscaled (by a power of two). In this case 780 is 3120/4, meaning that the app had to downscale it by 2^2. This heavy downscaling comes from the input height that is way larger than the screen height.

Thanks for these explanations Pierre Hébert.
Then, having pictures of the screen resolution (or less) could be a workaround?

Yes, your understanding is correct.
I forgot to mention something which is not documented nor obvious: the desktop wallpaper is efficient but requires that the image be no more than the screen size. There’s an alternative though: if you use a blank item and set its background or icon with a picture, you may be able to load larger images (but not infinite!) at the expense of speed. This is a tradeoff.

I just tried with a resized picture (to the screen resolution) and it works as expected : picture size in correct in preview.
The drawback of blank item is that it doesn’t “cover” the notification bar. Maybe I don’t know exactly what it is as I’m a noob with LLx. But I may don’t know exactly what is a blank item as I’m a noob with LLx (I tried with a panel).
Imo resizing pictures before using them is a better option. Maybe we can use script to do so : grabbing the screen resolution then using it to resize the picture.

Thanks for the tip Chris Chastain. I tried but it’s not good enough. When I zoom out I can see the system wallpaper. I guess I can expand the panel or disable zooming out but I feel this dirty.

Yes, in that case zooming would allow you to see past the edges of item. I was just addressing your comment of covering the notification bar.
I always size my image to screen size for wallpaper, as discussed previously.

Do you have a script for resizing pictures before applying them as wallpapers?

No, as it only takes a second to do. It’s easy to bulk resize an entire folder of images right on your device, but I usually employ some precise cropping also, in Photoshop on pc.

Lionel SANCHEZ pin the item, so that it doesn’t move nor scale. You may also turn off the “clickable” property.
