Byte[] of PDF into image
-
Hi, I need to convert a byte[] array generated from PDF into image and show it in the UI. I dnt want to store the image file anywhere in the disk.Conversion should be using in-built memory. I tried to convert byte into bitmap image using the following code. But image is not rendered in the UI. using (MemoryStream ms = new MemoryStream(bytes, 0, bytes.Length)) { BitmapImage im = new BitmapImage(); im.SetSource(ms); this.pdfImage.Source = im; } Is there anyother way to do this? Tools are also acceptable.

You can't convert a PDF into an image simply by converting it into a byte array. Without the conversion to an image, the
BitmapImageidentifies that it cannot display the byte array, so it doesn't attempt to display it. You might want to try this[^] library for the actual conversion (there's even a small sample on saving a PDF to a png file).*pre-emptive celebratory nipple tassle jiggle* - Sean Ewington

Hi Pete, I have tried this. But i am unable to add the dll in my Silverlight Application.

You don't add it to the Silverlight side - you add it to the ASP.NET side, and send the byte array to the Silverlight app. That is, after all, where you are getting the PDF from isn't it?
