One possible solution that comes to mind is to use the capabilty in many pdf
readers of taking a snapshot of a rectangular area of a pdf page (rather
like cropping), which can then be saved separately as pdf, jpg or whatever.
For example, I use PDF-XChange (the snapshot tool is on the tool bar), open
XnView and Import Clipboard (in the Fle menu). The image so created can
then be saved as you prefer.
