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.]

Shutter

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

sudo apt-get install shutter

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

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

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.

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).

Flameshot

sudo apt install flameshot

Be honest, compared with the most popular answer: Shutter, I would more like to use flameshot instead.

Below is the main reason;

Shutter is still heavier than Flameshot. Personally speaking, a screenshot is purely a screenshot, all I want is firstly selecting a range, freely adjusting it if I am not satisfied, adding some texts, or drawing important marks, then I can decide whether I want to copy it to clipboard or save it into file, that's it. I do not like extra pop-up a new window to let me do editions. I can do it using other type of tools.

While for some people may like more tools or multi-tabs (Shutter GUI is combined with "Tabs" of each screenshot) to dig deeper or at one time, I would not like that, let it be simple and basic.

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.
