> I have tiff images which are 512 X 10,000 pixels. The problem is when I
> open them, i can see a very narrow image, which fits into the screen, but it
> is almost impossible to see something there. It looks like it was scaled
> down to fit the screen. Is there a way to open this kind of image without
> scaling it (so it would actually be 512 pixels wide), and to have scrollbars
> to be able to view all the image, and it would not be a shrinked image.
