Increase size of thumbnails

#1

Post by diapanos » Sat May 04, 2019 10:55 am

Is there any way to increase the size of thumbnails?
It seems to be locked at 100% max and I would love to be able to go to at least 200%.
On a 32" monitor 100% thumbs are really small.

Is there any way?
None, other than using the ZoomIn and ZoomOut controls.

Thunar is hardcoded to employ 2 fixed dimension thumbnail variants, "normal" and "large". Even if, say, a custom plugin tried specifying a height/width value larger than 256 (aka large), that value would be overridden//clamped at 256, would be translated to THUNAR_THUMBNAIL_SIZE_LARGE aka "large"
ref: thunar-enum-types.c#L327

Instead of fussing with thunar "Zoom Levels", I coach the use of DetailsView. Right-click any imagefile item within a directory of interest, openWith your favorite image browser program (geegie? gthumbs, mirage) and let the image viewer do what it (not the filemanager app) does best. Use the best tool for the job, eh.

I'm not a fan of "icon view" in file managers (nor "thumbicon displayed for each item during details view") because the thumbnail generation imposes a HUGE overhead, chokingly huge when dealing with large directories... and the cache is a storage//backup nuisance (how often will I EVER revisit directory /x/y/z ? and is the file manager savvy enough to clean cached items for directories which have been deleted? usually not)
It seems to be locked at 100% max and I would love to be able to go to at least 200%.
Hmm, should be able to zoom to 400%.
Thunar uses the "tumbler" D-Bus thumbnailing service. You might investigate whether the content of ~/.config/tumbler/tumbler.rc is corrupt...
Can view tumbler.rc example here

You can make all icons bigger in Thunar, up to a point, with <Ctrl><Scroll Wheel>. You can also do that in Dolphin, but get much bigger icons and previews.

I know about scroll wheel & ctrl+ I'm trying to figure out if there's a way to get thumbnails larger than the max when you do that.
I could have sworn that Thunar in other distros had larger maximum thumbnails than Mx
