Gimp¶
Introduction¶
Gimp ( for GNU Image Manipulation Program) is a free and open-source raster graphics editor used for image retouching and editing, free-form drawing, converting between different image formats, and more specialized tasks.
GIMP is released under GPLv3+ licenses and is available for Linux, macOS, and Microsoft Windows.
It is very similar to other raster software like Photoshop.
Presentation of the goal¶
I took a drawing that I’ve made for my robotic team and I will use two software to correct and colorize this drawing in order to make some print on tee-shirt. So I will use :
- Gimp to assemble and correct the drawing
- Inkscape too colorize and add effect on the drawing
I will talk about Inkscape in the dedicated pages.
My work¶
Preparation¶
So first, I took photos of my drawing and of all the elements. I’ve draw elements separately so I can focus on the details, and I will assemble them after.

Assemble / erasure¶
The first step in gimp is to import all the separated drawings and assemble them into only one drawing. After that, I has to erase some parts of the drawing to clean it up.
