8. Layers

For some types of painting and image manipulation it is convenient to use multiple layers of images rather than a single image. For example you may want to overlay text or drawings over a photograph and then be able to move or edit each layer independently.

8.1 Creating

To start using layers with mtPaint you must first load the image you want to be the background. This is the most important step as all the other layers sit on top of this image (also, the size of the background image determines the size of the final composite image). Next you must create a new layer by using the Layers window ('L' key or View menu). You can then edit, manipulate, load to, or save this new layer just like any other image. The only difference is that this image can have a transparent colour which will show the pixels used on the background image (or lower layers if there are any).
