Clipping paths

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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.
