I wanted the colors to change after one key press but I didn’t know how to do it so I just let it be.

This image is of the drawing tool:

This is the image I uploaded:
http://www.openprocessing.org/sketch/113272

For the Image:

PImage img;

void setup(){
size(720,360);
background(255);
img = loadImage(“character.gif”);
}
void draw(){
imageMode(CENTER);
image(img,width/2,height/2);
}

For the Drawing Tool:

float x;
float y;
float lerp;
boolean colorchange;
PImage webImg;

void setup() {
size(720, 360);
background(255);
noStroke();
String url=”http://www.blogohblog.com/wp-content/pop/2010/11/40FishLogos_23.png”;
imageMode(CENTER);
webImg = loadImage(url, “png”);
image(webImg, width/2, height/2);
textSize(12);
String ch = “Click and Hold these Keys”;
fill(0);
text(ch, 10, 10, 70, 80);
