1.     Introduction

In this article, I will show how to remove the background of the image to put into the game by using GIMP.

2.     When should you apply this?

Many images or sprite on the Internet has the background color. It is not flexible to put into our game. That is when you need to remove the background color.

3.     Advantage and disadvantage

Advantage: GIMP is free and lighter compare to Photoshop.

Disadvantage: take time to remove the background with different colors.

4.     Requirement

GIMP 2.8.0

5.     Steps

–          Open the image by GIMP

–          Choose Layer -> Add Alpha Channel.

–          Use Fuzzy Select Tool () and click on the background. The background which has the same color will be selected. Then we press ‘Delete’ button.

–          If the image still has some background left, we will also need to remove them. After that we can cut the image  and resize it.
