clipping path in JPEG images

Hi to all

I want to extract clipping path from jpeg images, and I am trying many technologies but I can't get the right one:

I use visual C++ 6.0 and GDI+, so I tried Image::GetPropertyItem method, it worked on windows 2000, without gdi+ update; but on XP and when I update GDI+ the GetPropertyItem function does not get the adobe specific metadata in the file...

So I tried ImageMagick, I can get the clipping path in svg format (or postscript), but i can't transform it to GDI+ Graphic path (all my project use GDI+)? and i don't found how render Imagemagick to HDC...

many software do it, what's the technology, library, ... to use to get it working...

thank you
