This 'discovery' may be widely known - but maybe not.
Nothing that Adobe didn't intend - just something I didn't realise.

Summary:    Allows you to capture an arbitrarily high image of the 
whole or part of a PDF document to the clipboard as a graphical image.

_______

Acrobat Reader 6 (and before?) have a

    Tools / basic / Snapshot tool

feature that lets you select an area of the screen and capture it 
graphically to the clipboard.

If you select the whole screen you get a similar result to using the 
Windows print-screen feature.
Resolution is poor if the raw image is far larger than a screenfull 
when displayed 1 pixel per pixel.

BUT if you zoom the image until it is substantially larger than the 
screen will accommodate and then use the screen capture tool to select 
the whole image you get a copy of the whole virtual screen at 
appropriately improved resolution. When viewing a Protel A3 schematic 
converted to PDF this makes the difference between a poor and very 
good image. The resultant captured image may be retrieved from the 
clipboard by whatever software you wish.

The actual selection is a bit painful as you need to click and hold at 
one corner and then drag the mouse diagonally past the opposite 
diagonal corner and wait while the screen chuggingly (depending on 
your PC) pans to the other corner of the image - then release the 
mouse button and bob's your uncle. Annoying but effective.

The reasonably good help files explains operation of this tool but 
gives no clue about the greatly improved resolution that may be 
obtained by the above method.
