How to crop and convert a specific section of a PDF page into image?

Question

I have a pdf containing text and images. I need to crop a specific section from every PDF page and convert it into image. Please suggest me how can I do it. Remember I dont want to convert entire page into image. I need to crop some part from the page and then convert it into image.

Use the Snipping Tool in Win7 to cut the section of the screen you need and save it as an image.

If solutions above (Ghostscript) are OK and the only problem is to specify page region, try

gs -sDEVICE=png16m -o out.png -dFIXEDMEDIA \
   -dDEVICEWIDTHPOINTS=100 -dDEVICEHEIGHTPOINTS=200 \
   -c '<</PageOffset [-300 400]>>setpagedevice' \
   -f in.pdf

Sizes are in 1/72" points. Here: offset 300 from left, 400 from bottom (i.e. from lower left corner) and get 100x200 region. Note: [-300 400]are for images, but [-300 -400] are for display and high level (e.g. pdfwrite) devices. I.e. shifting down is positive and negative, respectively.
