Add and edit bitmap masks in Pixelmator Pro on iPad
Bitmap masks are pixel-based layer masks used to control the visibility of different areas in a layer. When created, the mask is fully white, and the entire layer is visible in the canvas. Painting on the mask in the canvas with black hides parts of the image. Painting with gray shades provides partial transparency, and painting with white reveals hidden areas again.
Add a bitmap mask to a layer
In Pixelmator Pro on iPad, select a Layer in the Layers sidebar.
Tap
on the layer, then choose Mask > Add Mask.
A white mask thumbnail is added to the Layers sidebar. The white indicates that no areas of the layer are hidden yet. To begin hiding areas in the layer, manually edit the mask.

When you add a bitmap mask to a layer, the mask thumbnail in the Layers sidebar is completely white, indicating that no areas of the layer are hidden yet. Painting over the mask layer (in the canvas) with pure black creates areas of transparency (shown as black brush strokes in the layer thumbnail); painting with pure white creates areas of opacity (shown as white brush strokes in the layer thumbnail); and, painting with shades of gray creates varying levels of transparency (shown as gray brush strokes in the layer thumbnail).
In Pixelmator Pro on iPad, select a mask layer in the Layers sidebar.

Automatically mask an image shot in Portrait Mode
When you open an image that was shot in Portrait Mode on iPhone or iPad, Pixelmator Pro automatically masks the background.
