does quickpdf have a "snapshot" function, or will it have available in the near future?

Well if you wanted to create an image snapshot then would you would do is adjust the cropbox dimensions to match the area of the page that you want to snapshot and then use a function such as RenderPageToFile to render the cropbox area of the page to an image.

If you want the snapshot to remain a bit then it is a little more difficult because while it is possible to crop the visible area of the page, this does not actually delete the objects that are outside of the visible area. They still exist internally within the PDF, they just aren't visible.
