PDFsharp & MigraDoc Foundation

Hello

I have been looking around for a decent api which can draw stuff on an existing PDF, but have yet to find anything good. Bbefore diving into it myself, I thought I should check with you guys first, so:

Using PDFSharp is it possible to:

1. Load an existing PDF file
2. Draw stuff on it (lines, curves, points...). Is it also possible to use transparency/apha channel here?
3. Save the edited PDF to file

Thanks a lot!

Hi!

Yes, can be done.

Look here:

Lovely, thanks!

The example uses DrawString only.

I take it it would be possible to use drawing primitives as well (curves, lines ...)?

Variations 2 and 3 do not use DrawString, they use a Path.

You can use all available drawing routines on any PdfPage object (newly created or opened from a file).

Thanks, it works like a charm.

Drawing lines and fancy curves is a breeze, but how do I draw a single point? Using does not produce anything (a line with zero length... well). Should I use for that or what do you suggest?
