PixelGrabber question

[buu]

I'm trying to access a pixels from a part of an image, but it seems not
working.
How could I access a pixels from only a part of an image?

Use a BufferedImage and use one of the getRGB() methods of that class.

It should work. I suspect there is a bug somewhere in your code. But
without seeing your code it impossible to know exactly where.

I don't have big code (just a few lines).

But, if I have a photo 100x200 pixels, and I would like to read just first
40x50 pixels, what should be syntax for PixelGrabber?

Carefully read the API docs at
<http://java.sun.com/j2se/1.4.2/docs/api/java/awt/image/PixelGrabber.html>
There is an example how to get all the pixels of an image. You have to
modify it for getting only the top-left 40x50 pixels of the image.
