If you can delete all “coloring” layers, let’s paint the cat’s image to your favorite color. If you erroneously erase a picture of another layer or draw a wrong line, you can use the Undo function to restore it. If you say “it is too much to erase and it is troublesome to erase with an eraser!”, You can clear the whole layer at once.If you press “Layer” -> “Clear” on the menu or “Delete” key on the keyboard, all the contents of the currently selected layer will disappear. Please properly erase the color using an eraser. Since “sample.mdp” has 4 layers, click the “coloring” layer in the layer window. Download sample.mdp How to clear the layer
