How to Make an Image into an Outline using GIMP

When I am doing any sort of stenciling, it sucks to waste printer ink on a color image, when I really just need the outline to cut around. It took me a little bit to figure it out in GIMP, so I decided to share how to do it.



Image Source




FYI: GIMP is a free "photoshop-esque" program. It does all the basics that photoshop can do. I recommend it for those who don't want to drop the dough on photoshop. (Me)

First, open your image in GIMP.  (File, open, choose your file)





Next, if you have chosen a color file, turn it into a black and white image by going to Image, then Mode, then Grayscale. 



To get your outline, go to Filters, down to Edge-Detect, and over to Edge. 





When the box pops up, click OK. 





Now you have a black image with a white outline. 



To get a white image with a black outline, go to Colors and down to Invert. 







I hope you find this tutorial useful, thanks for reading!

    1. I love it! It takes a little adjusting to go from Photoshop to GIMP, but it's a great program and has a lot of the fun filters and effects that photoshop has. I do all my editing with it !
      Thanks for stopping by :)

  3. To think of the days I wasted on trying to figure out Illustrator, exactly for this purpose--to get a simple outline. Thanks so much! I'd heard about Gimp years ago, but figured it was like the Paint program that's included in Windows. How wrong I was!!
    I'm all excited now! The possibilities...
    :o)
