GIMP Tutorial: Using Layers

This GIMP (GNU Image Manipulation Program) tutorial introduces the flexible feature called layers. When I first started drawing with GIMP I had no idea what they were or how to use them. After getting acquainted with the basic drawing and painting tools, I decided to try using layers. They are now a favorite feature. A layer is like a transparent sheet that you can draw on and overlay onto the picture underneath. They can help you compose more complicated images and effects. Layers may sound intimidating, but GIMP makes them easy to use.

Are you unfamiliar with this software? Please read this GIMP tutorial that explains how to draw with the basic tools.

How to Create a New Layer with GIMP
Bring the image window to the front. One of the menus at the top of is called Layer. Go to Layer>New Layer. A prompt will appear that allows you to customize properties of the layer. You can change the name of the layer if you like, but there is no need to change anything from the default settings. You definitely want to keep it transparent, so don't change that. Click the "OK" button and the new layer will be created on top of the existing image. The image window will always show all the layers together. The "Layer" menu will allow you to delete the active layer and some other managing tasks. The most comprehensive way to manage layers is to use the layer dialog box.

The GIMP Layer Dialog Window
When using layers, you will need to have this window open. If it does not automatically open when you start the program, you can open it from the main GIMP control panel. Go to File>Dialogs>Layers. This window allows you to manage them and select which one you are working on. The active layer is highlighted. You can also delete, rearrange, merge, and rename them. To change the active layer, click on it with your mouse. To change properties or delete, right click on the layer and select from the available options. To rearrange layers, drag and drop them in the order that you want. The first object in the foreground should be on the top because it will show in front of all the background and images behind it.
