Hi,

How are you increasing the view size? Using Nemo's inbuilt controls or the desktop wide zoom feature?

If the latter use the former. If the former can you screenshot to show us what you are seeing. Does hitting F5 to refresh the view make any difference

Hm, I was using Ctrl +.

Now I have increased the default zoom level for icon view from 100% to 200% in Nemo's preferences. And then in Nemo in the folder reset to default view (list in my case) and clicked on icon view to see them in the new default zoom level. Most pics are sharp now, a few which are sharp when opended are unsharp.

I somehow believe to remember I had found a place to resize the desired thumbnail pixel dimensions but I can not remember where.

Hi,

The backend thumbnailer used by Nemo defaults to producing thumbnails with maximum vertical / horizontal resolution of 256px (assuming the image being thumbnailed exceeds that dimension on one axis). I'm not aware of a way to alter that behaviour

There is a hidden away settings for the default display size of thumbnails - reducing it from the default value (64) results in blurry thumbnails. Increasing it can result in overlapping thumbnails.

To doublecheck what your setting is run the terminal command below

Code: Select all

dconf read /org/nemo/icon-view/thumbnail-size

I wonder why, when I run that command it doesn't output anything:

Code: Select all

lance@LM:~$ dconf read /org/nemo/icon-view/thumbnail-size
lance@LM:~$

Thanks - no output from a dconf read means it hasn't been changed and it's at the default value

Hi Smurphos :-) Thank you.

After following your information, I guess one or two thumbnails needed some time to display the resolution which I advised them by setting the icon view zoom level ...

Now they all are sharp.

Blessings, Klaus
