Create PDF - with SVG Graphic

I still have the troubles that the PDFWatermark didn't work - and now i tried to generate the watermark with an SVG Image, which i will print before the real pdf data.

The output looks good, but because of the pdf engine didn't work with GDI+, i has to convert the SVG into a GDI EMF.
the problem is, that the size of the pdf grows (needing about 280kb instead of 44kb) if i compare the output from coreldraw
the second problem is, that every text is transformed into curves and therefore i can't select the text in the pdf the anymore.

ah, just saw, that it seems to work ...

but an other question, is it possible, to compress the data?
i can see all in the pdf is plain data, if i view a pdf exported by corel & co, the data is in compressed form
