The Painter is the most basic painting tool. It allows you to paint blocks with a single type using a brush stroke.

The Mask Surface option allows only painting blocks which are adjacent to a non-solid block.

The Mode drop-down allows switching between Active Block, Clipboard and Gradient. The active block mode paints with your active block. The clipboard mode paints using your clipboard in a repeating grid pattern. The gradient mode is similar to The Gradient Painter but instead paints the gradient around the centre of the brush. The merge strokes option for the gradient mode stops the painter from overriding blocks that are in the gradient.
