Pscale
processing
Increases or decreases the size of a shape by expanding and contracting vertices. Objects always scale from their relative origin to the coordinate system. Scale values are specified as decimal percentages. For example, the function call 2.0 Pscale increases the dimension of a shape by 200%.
Transformations apply to everything that happens after and subsequent calls to the function multiply the effect. For example, calling 2.0 Pscale and then 1.5 Pscale is the same as 3.0 Pscale. This function can be further controlled with PpushMatrix and PpopMatrix.
