How to Outline Images in GIMP

How to Outline Images in GIMP

Hi everyone! Today I’ll show you how I make a border for
images in GIMP. I sometimes use this for my video thumbnails
to highlight some part of the thumbnail. Open the image in GIMP. Add a transparent layer by going to layer
– transparency – add alpha layer. I’m outlining this flower so I’ll remove the
leaves from the background. I have another video on different ways to
remove a background in GIMP. This time I’m using the fuzzy select tool
to select the background and pressing ctrl X to remove it. Once you’ve removed the background closely
enough, choose the select by color tool and click on the empty background so it becomes
selected. Then choose select – invert to select the
image you want to outline. Go to select in the menu and choose grow… You can try different sizes, just click undo
and try another one. I’m using 25 pixels here. Click ok. Now choose a color for the outline and use
the bucket fill tool to fill the outline. You can drag the outlined image on top of
a different background or keep the original background. You’ll find more GIMP tips like this on my
channel. Thanks for watching!

  1. I actually didn't know about the Grow/Shrink options, this is gonna make my life so much easier now, Thanks!

  2. Wow, I'm using GIMP for 2+ years now, and I had no idea this is a thing, especially didn't expect it to be so easy!

    Many thanks!!

    Edit: because it didn't work out first time, for whoever is reading this and the bucket fills the entire selection, on the bucket fill options, go to Affected Area(Shift) and select "Fill Similar Colors"!
