Class | PShape
Name | ### scale()
Examples |
    PShape s;

    void setup() {
      s = loadShape("bot.svg");
      smooth();
    }

    void draw() {
      background(204);
      shape(s);
    }

    void mousePressed() {
      // Shrink the shape 90% each time the mouse is pressed
      s.scale(0.9);
    }
Description | Increases or decreases the size of a shape by expanding and contracting vertices. Shapes always scale from the relative origin of their bounding box. Scale values are specified as decimal percentages. For example, the method call scale(2.0) increases the dimension of a shape by 200%. Subsequent calls to the method multiply the effect. For example, calling scale(2.0) and then scale(1.5) is the same as scale(3.0). This transformation is applied directly to the shape, it's not refreshed each time draw() is run. Using this fuction with the z parameter requires passing P3D or OPENGL into the size() parameter.
Syntax |
    sh.scale(size);

size | float: percentage to scale the object
x | float: percentage to scale the object in the x-axis
y | float: percentage to scale the object in the y-axis
z | float: percentage to scale the object in the z-axis
