most versions of Adobe reader have a "snapshot tool" that lets you take a "picture" of any portion of the pdf file. It's the icon that looks like a camera. Just click the icon then drag a box around the portion of the screen you want. When you release the mouse adobe will take a snapshot of that area and it will put it on your windows clipboard. Now go to paint or photoshop (or word or whereever) and press <ctrl> V (Paste) and paste the picture into the program.
