title: Read TIFF-File Header in C#
body: <p>I'd like to know the size of a tiff-picture represented by an Image. This Information can be calculated from ImageWidth and ImageLength by using ResolutionUnit and X/Y-Resolution as Parameters. However I'm not capable to extract These Information out of a tiff-picture.</p>
  
  <p>The description off the tiff-file-Header is found at <a href="https://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf" rel="nofollow">Adobe.</a></p>
  
  <p>As files can easily reach sizes above 400mb such as big maps, I'm looking for a way to only scan the Header of a TIFF-File to receive basic meta data like Resolution, ResolutionUnit, ResolutionX, ResolutionY and so on...</p>
  
  <p>Do you know a good way to extract these information?</p>
