4-1 homework

I was learning about how to save the background in what kind of file and the name of the file , earsing the drown line on the background. It was good for me to obtain the concept in this one.

void setup(){
  size(500,400);
  strokeWeight(3);
  smooth();
  background(205);
fill(255,255,255);
rect(55,3,387,380);
 
  fill(255,0,0);
  rect(0,0,50,50);
 
  fill(100,0,255);
  rect(0,50,50,50);

  fill(190,150,200);
  rect(0,100,50,50);

  fill(160,50,150);
  rect(0,150,50,50);
  //////////////
  fill(255,255,255);
  rect(448,0,50,50);
 
  fill(255,255,255);
  rect(448,50,50,50);
 
  fill(250,255,255);
  rect(448,100,50,50);
 
  fill(255);
  rect(448,150,50,50);
  fill(0);
  ellipse(475,175,2,2);
 
  stroke(0,0,0);
 
  PFont font; // Declare the variable
  font = loadFont("AmericanTypewriter-24.vlw"); // Load the font
  textFont(font); // Set the current text font
 
  fill(0);
  textAlign(CENTER);
  textSize(12);
  text("Save", 450, 25, 50,50);

  textSize(12);
  text("Eraser",450, 75,50,50);

  textSize(12);
  text("Clear",450, 125,50,50);
 
}
void draw(){
  if (mousePressed && mouseX>=0 &&mouseX<=53 &&mouseY>=0 && mouseY<=50)
    stroke(255,0,0);
   if(mousePressed &&mouseX>=0 && mouseX<=53 &&mouseY>50 && mouseY<=100)
     stroke(100 ,0, 255);
    if(mousePressed &&mouseX>=0 && mouseX<=53 &&mouseY>100 && mouseY<=150)
     stroke(190,150,200);
    if(mousePressed &&mouseX>=0 && mouseX<=53 &&mouseY>150 && mouseY<=200)
     stroke(160,50,150);
     if(mousePressed &&mouseX>=0 && mouseX<=450 &&mouseY>3 && mouseY<=50)
       save("line-##.jpg");
     if(mousePressed &&mouseX>=450 && mouseX<=500 &&mouseY>=50 && mouseY<=100)
     stroke(255);    
     if(mousePressed &&mouseX>=450 && mouseX<=500 &&mouseY>=100 && mouseY<=150)
        setup();
      if(mousePressed &&mouseX>=450 && mouseX<=500 &&mouseY>=150 && mouseY<=200)
         strokeWeight(2);
        
  
   if(mousePressed &&( mouseX >=65&&mouseX<=445 ))
     line(mouseX, mouseY, pmouseX,pmouseY);
}
