Scale. Illustration by George Brower

Move the mouse left and right to zoom the SVG file. This shows how, unlike an imported image, the lines remain smooth at any size.

SVG bot;

void setup(){
  size(200, 200);
  smooth();
  // The file "bot1.svg" must be in the data folder
  // of the current sketch to load successfully
  bot = new SVG(this, "bot1.svg");
} 

void draw(){
  background(102);
  translate(width/2, height/2);
  float zoom = map(mouseX, 0, width, 0.1, 4.5);
  scale(zoom);
  bot.draw(-140, -140);
