That depends upon what you mean by 'filter'. What problem are you trying to
solve?

Hmm. There was another person asking the same thing earlier this week. You
might want to dig through this week's messages, and see my responses.

Do you need this data while in user-mode, or kernel-mode? You can get all but a
few fields of the GDIINFO structure from user-mode calls. The remaining fields
require a kernel-mode driver. Which fields within the GDIINFO structure do you
need?
