Post subject:  How to draw an image from a byte[] or stream?
Hi,
I am trying to draw an image to a pdf. The only examples I have found are using XImage, which I can only seem to find a way to create using an image file path.

However, my files are saved in database as byte[], and the application that will be generating PDFs will not have permission to save files(so I cant save, open, delete). Is there a way to draw images using PDFSharp?

I am hoping to avoid having to purchase asppdf, which is quite pricey.

Thank you for any help.

Provided you're using pdfsharp and not migradoc:

Code:
            // byte[] jpegdata contains the jpeg image
            using (MemoryStream ms = new MemoryStream(jpegdata)) {
                using (Image img = Image.FromStream(ms)) {
                    using (var xi = XImage.FromGdiPlusImage(img)) {
                        _pdfGfx.DrawImage(xi, ip.dx, ip.dy, ip.dw, ip.dh);
                    }
                }
            }

With version 1.50 beta 2, there is a solution for that works with MigraDoc: pass the image as a string when you call AddImage():

This method applies to MigraDoc only.
With PDFsharp you can create an XImage from a Stream.
