Examples

    PGraphics pg;

    void setup() {
      size(100, 100);
      pg = createGraphics(80, 80, P3D);
    }

    void draw() {
      pg.beginDraw();
      pg.background(102);
      pg.stroke(255);
      pg.line(40, 40, mouseX, mouseY);
      pg.endDraw();
      image(pg, 10, 10);
    }

Description

Main graphics and rendering context, as well as the base API implementation for processing "core". Use this class if you need to draw into an off-screen graphics buffer.
