New document
Create a document and set the canvas width, height, and background color.
Drawing
Select a paint layer and a pencil brush. Set the brush size, then draw a stroke. With a pressure-sensitive pen, vary the pressure to change the stroke. Use the eraser to remove pixels or Undo to revert the last operation.
Saving
Save the document in a format that preserves its layers. Export a separate image when a flattened copy is required.
