These options let you progressively increase or decrease the size of objects in the brush. Use Line width to set the basic size of the objects.

Scaling changes by:

Random

 Gives a random scaling change between objects. The slider limits the difference; for example, 50-200% limits the scaling to between 50% to 200% of the original size.

Pressure

 This has an effect only when using a pressure-sensitive input device such as a graphics tablet. The scaling is controlled by the pressure you applied when creating the line.

Randomize

 Generate a new random set of scaling changes. If you prefer the previous values, click Undo.
