I'm just going throught the image tutorial on how to import an manipulate jpgs and whatnot. I changed the code a little, but I can't figure out why I'm getting this error... its always when the 3rd image (2.jpg) is loading. I tried duplicating the 2nd image, but it seems to be the code...

oh and I'm only displaying every 4 pixels to make the framerate faster.

Code:

PImage pimage;
int i = 0;
int timer = 1;

void setup(){
  colorMode(HSB,100);
  background(0,0,0);
  frameRate(30);
  size(640, 480);  
  pimage = loadImage("0.jpg");
}
void draw(){

    println("timer is"+timer);
    if(timer>=60){
      pimage = loadImage(i+".jpg");
      i++;
      timer=1;
      println("i is now "+i +".jpg");
      int loc=0;
    }   
      loadPixels(); 
      // Since we are going to access the image's pixels too  
      pimage.loadPixels(); 
      for (int y = 0; y < height; y+=4) {
        for (int x = 0; x < width; x+=4) {
          int loc = x + y*width;
      
          // The functions red(), green(), and blue() pull out the 3 color components from a pixel.
          float r = red(pimage.pixels[loc]);
          float g = green(pimage.pixels[loc]);
          float b = blue(pimage.pixels[loc]);
      
          // Image Processing would go here
          // If we were to change the RGB values, we would do it here, before setting the pixel in the display window.
          //float adjustBrightness = ((float) mouseX / width) * 8.0;
          float adjustBrightness = timer/2;
          
          r *= adjustBrightness/4;
          g *= adjustBrightness;
          b *= adjustBrightness;
          // Constrain RGB to between 0-255
          r = constrain(r,0,255);
          g = constrain(g,0,255);
          b = constrain(b,0,255);
          // Make a new color and set pixel in the window
          color c = color(r,g,b);
          pixels[loc] = c;

          // Set the display pixel to the image pixel
          pixels[loc] =  color(r,g,b);  
          
        }
      }
       
      updatePixels();
    timer++;
  //}
}
 

yeah sorry.... the error is on line 30

ohh and i resized all the images to be exact size... and no more errors!!

I guess it doesn't store pixel info thats out of frame, or becomes problematic...

thanks!
