Magick.NET Image Resize results in 0 byte file

Question

I am trying to resize an image using Magick.NET, but after I call the Resize function the FileSize property reads 0. What am I doing wrong?

var image = new MagickImage(file.InputStream);
fileSize = image.FileSize; //will read something > 0
image.Resize(80, 80);
// image.FileSize will read 0
image.Write(stream); // results in a 0 byte stream

using the result of Resize() instead of the orig image? – lboshuizen Nov 06 '14 at 15:14 — lboshuizen, Nov 06 '14 at 15:14
@lboshuizen Resize is void. – Matt Baker Nov 06 '14 at 15:16 — Matt Baker, Nov 06 '14 at 15:16

It looks like I was (mostly) wrong about the effects of FileSize reading 0 after calling Resize. It does read 0, but calling Write doesn't actually write nothing, it does populate the output stream as expected. The real problem in my case came from code that followed this that consumed the contents of stream without resetting its Location back to 0.
