How would I go about getting for example 300dpi pictures of work done? I need to have pictures to hand in as its a course requirement to have 3 images at 300dpi. I know I can change the applet size but how would I go about getting 300dpi?

This is the source:


int NUM = 15;
boolean myToggle;
Wurm[] w = new Wurm[NUM];


void setup() {
 frameRate(30);
 size(600, 400);
 background(random(0,255),25,180);
 smooth();


 for(int i=0;i<NUM;i++) {
   w[i] = new Wurm(random(width), random(height));
 }

}



void draw() {
 for(int i=0;i<NUM;i++) {
   w[i].draw();
 }
}


class Wurm {

 int wurm_size = 3;             // Width of the centipede
 float xpos, ypos;              // Starting position of centipede
 float xspeed = random(0,2.4);  // Speed of the centipede
 float yspeed = random(0,1.2);  // Speed of the centipede

 float xdirection = random (-1,1);  // Left or Right
 float ydirection = random (-1,1);  // Top to Bottom

 float myAngle = 0;


 Wurm (float theXpos, float theYpos) {
   xpos = theXpos;
   ypos = theYpos;
 }


 void draw() {

   xpos = xpos + ( xspeed * xdirection );
   ypos = ypos + ( yspeed * ydirection );

   if (xpos > width-wurm_size || xpos < 0) {
     xdirection *= -1;

   }
   if (ypos > height-wurm_size || ypos < 0) {
     ydirection *= -1;

   }


/* Draw the centipede */
   myAngle += random(0,0.015f);
   pushMatrix();
   translate(xpos,ypos);
   rotate(myAngle);
   stroke(random(0,1),random(0,2),random(0,3),10);
   line(0, 0,random(-45,-30), random(-45,-30));
   line(0, 0,random(-45,-30), random(-45,-30));
   line(0, 0, -random(-45,-30), random(-45,-30));
   line(0, 0, -random(-45,-30), random(-45,-30));
   popMatrix();

   pushMatrix();
   translate(xpos,ypos);
   rotate(myAngle);
   stroke(random(0,10),random(0,207),random(0,255),20);//stroke colours
 
   line(50, 0,random(-45,30), random(-45,30));
   line(50, 0,random(-45,30), random(-45,30));
   line(50, 0, -random(-45,30), random(-45,30));
   stroke(255,20);
   line(50, 0, -random(-45,30), random(-45,30));
   noStroke();
   fill(255,0,129,10);
   rect(50,50,5,5);
   fill(255,118,0,7);
   ellipse(50,-30,7,3);
   popMatrix();
 }
