In Chipaca's to Managing files and sync scenarios there's a screenshot with certain highlights. The highlights are the following:

  1. A row of a GUI list is highlighted by the other parts of the screenshot being darker.
  2. A check mark is highlighted by being circled by what looks like a (orange) crayon.

How do I create both of these highlights on a screenshot? Is there an automated process?

The screenshot I'm referring to looks like this:

Ubuntu One Control Panel “Cloud Folders” tab, with a row highlighted to illustrate the point in the text

This should be a plugin request for Shutter ;) –  Achu Sep 12 '11 at 18:11
    
@Chipaca Does any of the answers below correspond to how you did it? –  N.N. Sep 29 '11 at 9:11

Sorry it took me so long to find this, for some reason I didn't get any of the notifications (?). I did it manually. The accepted answer is more efficient than the way I went about it, but even so it only took me a couple of minutes, while my brain was working on the wording of the answer anyway. –  Chipaca Feb 10 '12 at 11:30
    
@Chipaca I did notify you twice indeed. Perhaps there is some glitch. Anyway, I am happy to hear how you went about. –  N.N. Feb 10 '12 at 11:37

Here's a guide for The Gimp Install gimp:

Create Higlighted Rectangle

  1. Select Rectangle Tool:

    • tick Feather Edges choose Radius e.g. 5.0 pixels for smooth borders
    • tick Highlight to highlight the selection

    enter image description here

  2. Select area to highlight

  3. Select -> None to remove selection.

The selection is now higlighted

enter image description here

Note: in some versions of GIMP the highlighting may be removed as soon as we select another tool or save the image. In this case we can proceed as follows to keep the area highlighted:

  1. Invert the selection (Select --> Invert or Ctrl+i).
  2. Bucket fill the background with black 30% opacity.

Create Crayon

  1. Select Ellipse Tool to select area for crayon
  2. Select -> Border e.g. with 8 pixels
  3. Painbrush Tool choose brush e.g. Galaxy, choose color e.g. yellow
  4. Paint selection until happy

enter image description here

Is some of these steps possible to automate in any way? –  N.N. Sep 12 '11 at 18:56
    
You can make the highlight part easier - see edit ;) –  Takkat Sep 12 '11 at 19:26

Another way of doing the ellipse painting is by doing it as a path (which you can create with selection-to-path on the paths tab of the layers-and-paths window) and then doing "stroke path" with an appropriate brush set. (I'd be more specific but I don't have a GIMP install handy.) –  fluffy Sep 12 '11 at 20:25
    
@luffy: I should have known this :D. I had started to do the same process in the GIMP, but I'm more accustomed to doing path related stuff in Inkscape :P. –  RolandiXor Sep 12 '11 at 21:22
    
As soon as I click the ellipse tool, the highlighting disappears. Is there any way to keep the highlighting? –  Exeleration-G Dec 20 '12 at 15:05

You can do this in editors such as Pinta, Shutter*, the GIMP, etc.

The process may vary, but one way to do it, would be to place a translucent square/rectangle in a second layer above the image, and then to cut out the part that you want to glow.

Example workflow:

enter image description here

  • Open your screenshot in Pinta.
    1. Create a new layer.
    2. Select the new layer
    3. Choose the paintbucket tool.
    4. Change the colour to black, but set the opacity to 150.
    5. Now use the rectangle selection tool to select the area you want to highlight.
    6. Fill the layer with this colour.
    7. Hit delete.
  • The image should now be highlighted.

example


* Shutter is more for accomplishing the reverse effect.

You haven't included the second highlighting technique I mentioned. –  N.N. Sep 12 '11 at 18:10

That's why I'm wondering if Chipaca got some steps automated. Seems a bit too demanding to do advanced image editing for every screenshot. –  N.N. Sep 12 '11 at 18:30
    
@N.N.: I was going to add it, but it's too much work with standard methods. So I'll leave my answer as is. –  RolandiXor Sep 12 '11 at 18:35

  1. Take a screenshot

    I use shutter and gnome-screenshot to take screenshot, you may use any one of them.To install them, use the commands.

    sudo apt-get install shutter
    sudo apt-get install gnome-screenshot
    
  2. Install gimp
    We will need this for the editing.Install it with

    sudo apt-get install gimp
    
  3. Get the screenshot into gimp I dragged the image into gimp.You may use file -->open

  4. The fun begins

    • We first select the part we want white.We can hold Shift to select multiple areas. Then we invert the selection using Ctrl+I enter image description here
    • Then we select the paintbrush tool. enter image description here
    • Now we change the opacity and increase size.
      enter image description here
    • Paint everything.If it's darker, change opacity and try again.For me, 50% was fine. And the end result is.
      enter image description here

NOTE: The options for gimp were available easily for me because I have customised it a lot. Use some gimp tutorial to learn how to use it.
