    How can I get the visible bounds of a picturebox?

    Well, I have a class which magnifies the picture inside a picturebox. The problem is that it takes SOO much memory. So instead of magnifying the whole picture, I want to just magnify the visible part of it. For example let's say I have a picturebox on a form, and that the picturebox is larger than my form, so some of it is not visible on the screen, and some of it is visible..... how can I get the bounds of the visible part? I'm gussing there should be a way

    This is assuming that the picture box is in the bottom right corner. You might need to change it.
    Viewable:
    width = form1.width - picbox.left
    height = form1.height - picbox.top

    That seems too easy. Something tells me that wasn't what your looking for.
