How to smooth a scanned image using Gimp


Question

I have drawn an image which I then scanned into the computer and saved as a png.

I just want to make the lines smooth on the image. The image is a logo enter image description here

Any help is much appreciated. I am using GIMP 2.8

In order to make lines smooth, you have to vectorize the bitmap in applications like Inkscape:

You can import the image and trace it: enter image description here

After the tracing operation the image is vectorized and you can work on the nodes. For example you can simplify the path, which is an automatic operation: enter image description here

In this example the left image is the traced one and the right image is obtained simplifying the path (less nodes and more smooth). Obviously after this operation you can work on single nodes in order to adjust the details (in the example the eye of the lion needs a little work).

In GIMP you can blur the image in order to soften the edges, but I suggest you to vectorize the image.
