Scanning Image Pixel by Pixel

[the_transltr]

I just want to know some idea on how to scan every pixel from an image file and put it into an array.

[roots]

BufferedImage (Java 2 Platform SE 5.0)

look for getRGB

import java.awt.image.*;
import java.awt.*;
import java.applet.*;

public class Sprite {
private String name;

public int[] b;
public int w;
public int h;

public Sprite(Applet a, String filename, int width, int height) {
try {
name=filename.substring(0, filename.indexOf('.'));
w=width;
h=height;
Image img=a.getImage(a.getDocumentBase(), filename);
b=new int[h*w];
PixelGrabber pg= new PixelGrabber(img, 0, 0, w, h, b, 0, w);
pg.grabPixels();
if (pg.status()==192) {
throw new RuntimeException("error loading "+filename +" sprite");
}
//now b[0] is the leftest pixel of the top
// b[w-1] is the rightest pixel of the top
} catch(Exception e) {
e.printStackTrace();
}
}
}

depends upon the format of the image
bitmap stores 3 variables for each pixel
and there must be some api for doing image processing
google for that
