Description Ben Pearre 2009-10-06 08:32:02 UTC 
Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Add a best-guess image-scaling mode to Wallpaper Positioning (currently "Scaled & Cropped", "Scaled", "Scaled, keep proportions" etc):  If the aspect ratio of a photo is close to that of the screen, then crop a little bit so as to fill the screen.  But if it's very different (eg. monitor is wider than it is tall but photo is taller than it is wide), then cropping will be bad, so just display the picture whole.

I'm assuming "Scale & Crop" takes the largest rectangle from the center of the image that has the same aspect ratio as the user's screen.

It would be lovely to have a wallpaper mode that behaved as follows:

If Scale & Crop would cut less than x% off the image, then Scale&Crop.  Otherwise, Scale to fit (keeping aspect ratio).  Ideally, x would be a user-settable parameter, but something like 30% would probably be a decent starting point.

Note that there are four common aspect ratios for photographs: 4:5 and 5:4 (point-and-shoot portrait and landscape) and 2:3 and 3:2 (ditto for SLRs).  In addition, there will be custom crops, screenshots from 16:9 movies, etc...  Monitors have a plethora of different aspect ratios, but 3:4, 4:5, 16:9 and many more are out there (as well as rotated modes).

Hello!

This feature request was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this feature request is already implemented in Plasma 5, or is no longer applicable.

Accordingly, we hope you understand why we must close this feature request. If the requested feature is still desired but not implemented in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting

If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging

Thanks for your understanding!
