Can't load an image and get the pixels right

Hello,
I am quite new to Processing, but still amazed by the simplicity of the language.
Still, I would like to reproduce an example from the tutorial "Images and Pixels".
I can load an image and show it on the screen using the image command, but when I try to show it on the screen pixel by pixel as in the example, all I get is some strange lines, completely different from my original image.
I am using Processing 1.5 on Windows 7.
I post my code below.
Thanks,
Samuel
- PImage img;
- void setup() {
- size(600, 500);
- img = loadImage("Sachan 2.png");
- }
- void draw() {
- loadPixels();
- // Since we are going to access the image's pixels too
- img.loadPixels();
- for (int y = 0; y < height; y++) {
- for (int x = 0; x < width; x++) {
- int loc = x + y*width;
- // The functions red(), green(), and blue() pull out the 3 color components from a pixel.
- float r = red(img.pixels[loc]);
- float g = green(img.pixels[loc]);
- float b = blue(img.pixels[loc]);
- pixels[loc] = color(r,g,b);//,rand(255));
- }
- }
- updatePixels();
- }
