Adding a color swatch

What is simulated pressure sensitivity?

It is a property that makes lines get thinner and more transparent at the beginning and end of strokes. 



For example, the stroke of a default pencil fades at the tip. The speed of your stroke affects how long the fading portion is.



In the Brush Editor, the Min and Max values for Size and Opacity drive this.



Therefore, if Min is 2 pixels and Max is 8, the synthetic pressure will apply this range to the ends of strokes, based on the speed/intensity of your strokes, creating what we call "simulated pressure sensitivity".

How does Fill work?

The Fill tool is found in the Brush Editor and marking menu.



The Fill tool floods a closed area with paint.



If a layer has enclosed areas (the area is surrounded by pixels of a different color), and you tap inside one of them, only that region is flooded with paint.



If you tap outside an enclosed area, paint floods the outer area.



Fill only floods the entire layer with paint if the layer is empty.

Therefore, though you may see regions created on other layers, if you are on an empty layer, paint will completely flood the empty layer and ignore any pixels on other layers.
