Whenever I take screenshots using the default screenshot tool on my Ubuntu 11.10 (unity), the image does not look as good as the screen itself (the quality is deteriorated). So I would like to take high quality screenshots. Is there any tool for this?
[The resolution of the image is the same as that of my screen, but surprisingly, it does not look as good as the original one.]

If you don't want to install yet another program give Gimp a try. File->Acquire->Screen Shot...

    Really nice option. FYI my GIMP v2.8.2 has the option at File -> Create -> Screenshot – Soundar Rathinasamy Nov 30 '12 at 19:52
  • Good one! Didn't know Gimp could take screenshots. – Marcelo Aug 18 '17 at 13:27

Shutter

My suggestion would be to use a screen capture tool such as Shutter.

If you look in the preferences - you can define what the compression ratio is together with the graphical format.

  • This was very useful... somehow the default compression got set low on Shutter, and images were coming out crappy for me. Bumping the compression quality up fixed everything. (Think it might have been a version bump/update). – metasoarous Jun 9 '15 at 22:35

    @metasoarous: My JPG quality was set to 9 which incidentally is the max quality setting for PNG. My guess is that the default format was changed from PNG to JPG and that the quality setting didn't get updated. – Alexander Torstling Jul 13 '15 at 12:38
  • Many thanks. In case anyone else is wondering this change affects the results whether you are saving the image to a file, or just to the clipboard. – kabdulla Jan 19 '17 at 6:07

The images are fine, but they look blurry because the default Gnome Image viewer is set to "Best Fit" instead of "Normal view", which resizes images slightly, making them appear blurry. Unfortunately, there seems to be no preference or setting that allows changing this. Instead just install another image viewing app, and make it the default:
sudo aptitude install gthumb
It can be customized to view images 1:1 by going Edit -> Preferences -> Viewer -> Set to actual size. Then go View -> unselect "Thumbnail pane" (with this on, it seems to interfere with 1:1 viewing). Test it, then if so make it the default app by going ubuntu "System Settings" (top right corner of your desktop) -> System info -> Default applications -> Photos -> gThumb.

  • rezising the image viewer window makes it look better, good one – mau Aug 12 '15 at 0:59

How are you viewing the resulting image?

The default tool gnome-screenshot does take sharp images but if you open them in the default Image Viewer and knock the mouse scrollwheel (or the Best Fit option is in effect) then the quality degrades significantly. In Image Viewer press Ctrl+0 (zero) to revert to Normal view (100% scale).

It seems the built-in screenshot utility (by pressing Shift+PrtScr ) overly compresses the snapshot when its width goes beyond some extent or the H/W ratio is too high, causing the captured screen texts blurry. You can decrease the H/W ratio by including more area or reduce its width to see the difference.
