I'm trying to create clipping rectangles around text, but can't seem to get it right. Any information on using clipping paths would be appreciated.

If I clip a fixed area, e.g. half the page, it works as expected. If I draw my paths instead of clipping them, the rectangles are in the correct position. But if try to clip around text, most of the text is missing.

Here's a snippet of the code I'm using.

pdfdoc.StartPath X1, Y1
pdfdoc.AddLineToPath X2, Y1
pdfdoc.AddLineToPath X2, Y2
pdfdoc.AddLineToPath X1, Y2
pdfdoc.ClosePath
pdfdoc.SetClippingPath

Update: It seems to only use the first clipping path per page. Is that correct? I'd REALLY like to be able to set arbitrary clipping paths.

Solved: I just had to check Adobe's PDF reference. Save the graphics state before clipping and load it when done.
