In Photoshop the Magic Wand tool has a contiguous setting, that when enabled, will cause the Magic Wand to select only one area. If disabled you will end up with several areas of the same color (depending on picture and settings of course).

Here's a picture to illustrate what I fail to explain:

Can I do this in Gimp?

Yes you can.

In Gimp you have two tools:

The Fuzzy Select Tool

enter image description here Which will allow you to choose an area based on the color and the similarity using a few additional tools like thresholding, mode, selection by composite, channel, saturation and value and a few more.

In the next example I am using the Fuzzy Select Tool which is selecting only the white color around the logo.

enter image description here

Using the same tool, I am adding inner sections of the logo by keeping the Shift key pressed while clicking on the sections to add.

enter image description here

The Select by Color Tool

enter image description here With this tool you can choose which color base regions you wish to choose with just a click, using additional tools, like: mode, selection by composite, channel, saturation and value and a few more.

In the next screenshot I am using the Select by Color tool in order to click into the center oval of the number nine in the logo in order to choose all the regions that are similar (based on the threshold) to the color I picked when clicking.

As in the previous tool, you can keep the Shift key pressed while clicking in order to continue adding adjacent areas.

enter image description here

Based on thresholding, the selection may be more accurate.

Depending on the mode that you use, you can have the effect that you wish. In the next example I have activated the second mode which will act as additive in both the Fuzzy and Color selection tools.

  • DoR: Thank you for the edit, I have transparent windows using compiz and some times (like this) the screenshots or partial screenshots shows part of my stuff in the desktop. Thank you!

    Unfortunately, I think neither can be restricted to select only contiguous areas (unlike the "Foreground Select Tool").

  • @haridsv - No, as stated in this answer, the "fuzzy select" tool does select a contiguous area (always). Indeed, that's the (main) difference between it and "select by color". if "fuzzy select" is selecting more than you expect, lower the threshold. Be sure "Diagonal neighbors" is not checked. Make sure you are selecting in the layer you intended to.
