Hi everyone,

I've written a brush class which simulates a brushstroke (in a basic way). I need to be able to make these brushstrokes in a PGraphics buffer, but I can't seem to get it to work....

code here: http://pastebin.ca/1840461

I wrote the program below as a simple model - just drawing a rectangle instead of something more complicated....and this does work......what is the difference

Code:

PGraphics pg;
rectangle r;


void setup()
{
   size(300,300);
   pg=createGraphics(width,height,P2D);
   r = new rectangle(100, 100, 50, 60, PI/8, color(100, 200, 100));
   
   pg.beginDraw();
   r.render();
   pg.endDraw();
   
   image(pg, 0, 0);
}

void draw()
{
  
}

class rectangle
{
  float x,y,w,h;
  float angle;
  color c;
  
  rectangle(float x, float y, float w, float h, float angle, color c)
  {
    this.x=x;
    this.y=y;
    this.w=w;
    this.h=h;
    this.angle=angle;
    this.c=c;
  }
  
  void render()
  {
    pg.rectMode(CENTER);
    pg.fill(c);
    pg.pushMatrix();
	pg.translate(x, y);
	pg.rotate(angle);
	pg.rect(x,y,w,h);
    pg.popMatrix();
  }
}
    
 

Yes, thanks. Why does that make a difference?

(I thought it didn't work properly at first, but I'd forgotten to put in pg.smooth() which makes the brushstroke look much nicer).
