How can I select a region in an image file, and hide or blur the region (e.g. barcode, or personal information) in any way that you think is reasonable?

I have tried pinta. I first select a rectangle region, and then try to use paint bucket to fill the region, but it doesn't fill the region at all, or I don't know how.


  • What do you mean by hide ? Does it hide completely or kinda blurring it ?

    Since you seem to prefer a solution with pinta, make that clear in the question itself rather than as comments to answers.

Open the image in GIMP. Click Tools > Selection Tools > Rectangle Select Tool. Outline the area you wish to blur.

Next, click Tools > Paint Tools > Smudge. Use the mouse to smudge the selected area as desired.

Next, click Select > None. Next click File > Export As... Export the file as any file format you wish. Exit GIMP.

  • Thanks. Is it possible to use pinta? I guess so, but I don't know how

    All I can get pinta to do is crash, so I haven't any suggestions.

You can give Shutter a try:

sudo apt install shutter

If you're using 18.04 or a later version, then you should install the required dependencies in order to edit in Shutter (Skip if you use 16.04):

wget https://launchpad.net/ubuntu/+archive/primary/+files/libgoocanvas-common_1.0.0-1_all.deb
wget https://launchpad.net/ubuntu/+archive/primary/+files/libgoocanvas3_1.0.0-1_amd64.deb
wget https://launchpad.net/ubuntu/+archive/primary/+files/libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb
sudo dpkg -i libgoo*.deb

Open the Shutter program, take the screenshot or open your image file, then click "Edit", this will bring you to editing process.

To blur, click the Blur tools.

Then, you can select a region you want to blur/censor.

Save it, and see your result.

The result will be saved in the ~/Pictures directory in your home folder.

You can do that also with Pinta: EffectsBlursGaussian Blur.

I've also written a more detailed tutorial with screenshots on my blog. Also checkout the official Pinta docs.
