New Post: Problem with some PDF files

The exact results are a bit unpredictable. I get different results when i run it on different computers (Windows Server 2008 R2 and Windows 7).

Using Latest versions of both.

On the windows server, it is using 64 bits Ghostscript, on the Windows 7 it is using the 32bit version.


The code for converting is:

(The stream is just a filestream)

            using (var rasterizer = new GhostscriptRasterizer())
            using (var memoryStream = new MemoryStream())
            {
                stream.CopyTo(memoryStream);
                memoryStream.Seek(0, SeekOrigin.Begin);

                rasterizer.Open(memoryStream, gsversion, false);

                return this.CreateTiffFile(color, rasterizer);
            }

Snippet from CreateTiffFile

var page = rasterizer.GetPage(300, 300, i)

This fails with an ArgumentException at on my Windows 7 computer:

If i debug with the soruce for Ghostscript.Net available i see that it is because it tries to create a document with zero height and width.
