Hey guys I have this C# code to convert any image file to.pdf using pdfsharp.dll. But I want to select multiple images for conversion please help. Here's my code (plz note. With PDFsharp 1.50 beta 2, a new feature was added: MigraDoc now accepts filenames that contain BASE64-encoded images with the prefix 'base64:'. In this case, the filename does not refer to a file, the filename contains all the bits of the bitmap in an ASCII string with the BASE64 encoding. Shows how to deal with PDF objects that are not (yet) covered by specialized PDFsharp classes (as an example it adds an OpenAction to an existing PDF file) XForms: shows how to create an XForm object from scratch. You can think of such an object as a template, that, once created, can be drawn frequently anywhere in your PDF document.

I am attempting to convert a pdf to jpeg using PDfSharp.
Here is my code:
The line:
if (resources != null)
is returning false. I am not sure what resources is supposed to contain, but it seems to be important for the rest of the conversion. I copied this code from the pdfSharp example site. Could there be an issue with my PDF? I made it using word 2010.Any help would be greatly appreciated!

If you want to convert a PDF to a JPEG, and want to do it with a free software library, consider ImageMagick. This runs on all major platforms, so you will be fine on Windows. It can be kicked off on the command line, and you can set your preferred lossy compression level.
Edit: ah, I've seen on another question that you're using a .net interface to ImageMagick. That's great if you can get it to work, but you may find it easier just to use the

How to export a PDF page as an image using PDFsharp .NET library, for pixel level manipulation?
For example, something like, System.Drawing.BitMap.GetPixel()
I am trying to find out empty area (all white, or of any colour) inside a PDF document, to write some graphics / image.

I have tried this, but it is not working.
Why the following code is not working as expected?
Stephen hawking grand design pdf. Bitmap.GetPixel always returns 0.

The answer can be found in the PDFsharp FAQ list:http://www.pdfsharp.net/wiki/PDFsharpFAQ.ashx#Can_PDFsharp_show_PDF_files_Print_PDF_files_Create_images_from_PDF_files_3
PDFsharp creates PDF files, but it cannot render them.
The call
does not initialize any bits of the bitmap and does not copy anything from the Graphics object except for the DPI setting of the Graphics object. Graphics objects draw things, but they do not remember what they have drawn and they cannot re-create the drawings in a call to
new Bitmap(..)
. This does not work with the Graphics class from Microsoft, this does not work with the XGraphics class from PDFsharp either.The XGraphics class from PDFsharp can be used to draw on PDF pages and it can be used to draw on bitmaps, on a printer, or on the screen - it can draw on PDF pages and on any DC you can get from Windows. Same goes for MigraDoc.
So if you want to create PDF files and bitmaps with the same contents, PDFsharp and MigraDoc can help.

But PDFsharp does not provide any way to render a PDF page to a bitmap.
