Slowly revealing parts of an image with the mouse
Jul 10th, 2009, 6:49am  
Hi all,

I was wondering why the code below does not reveal the point where my mouse is on the screen?  Any ideas?

Code:


PImage img;
int columns, rows;
int i, j, x, y, c, z;
Hashtable hm = new Hashtable();


void setup() {
 
  // Get the pic info
  img = loadImage("400-high.jpg");

  // Stage size
  size(img.width, img.height, P3D);
   
 
}

void draw() {
  
   loadPixels();

     x = mouseX;
     y = mouseY;
 
     pixels[(y) * img.height + (x)] = img.pixels[(y) * img.height + (x)];
     updatePixels();

 }
