[Image-SIG] pdf to image

[Christopher Barker]

OK, a bit (or a lot!), but once someone else brought it up---

I've used similar code. However, in my case, we're thumbnailing 
arbitrary pdfs, which could be any size -- usually they are US-letter or 
A4, but there can be poster-sized ones there too. So my question is:

How to I tell ghostscript to make the resulting image a given size (say 
100x100 or less), or how do I use ghostscript to tell me the size of the 
pdf at hand, and then I could calculate the DPI myself? Any ideas?

To the OP: you don't seem to be specifying the DPI that you want. The 
default may be OK, but  you may want to be explicit:

-r150

gives you 150dpi.
