Hi everybody...i am trying to covert to pdf from a component that i have to draw...

I am exporting some shapes to a png picture file and after trying to importing into the pdf file....but the images are non transparent!!!

How can i get it??

The pictures files are png and are transparents!!!

I am using this:

Code:

document = new PdfDocument();
page = document.AddPage();
XGraphics gfx = XGraphics.FromPdfPage(page, XGraphicsPdfPageOptions.Append);                
XImage image = XImage.FromFile(path);
gfx.DrawImage(image, new XRect(posx, posy, posw, posh));

Thanks

Make sure to set PDF version to 1.4 (or higher) if you use images with transparency. (1.4 is the default with PDFsharp 1.2).

well, when i show the document.Version...is 14...so i think that's the version!!

The dll file is PdfSharp.dll and the version is 1.2.1269.0

But is it possible to show one image over other without white spaces between??

Can anyone send me an example or something...? i can even send you my images to test it!!!

Many thanks
