title: Complex Transform of Image file in C#
body: <p>I have a project in C# where we take multiple fixed sized images and generate a composite image.  The fixed sized images require some distortion which is not simple skewing.  So from a perfectly square image, I need to do this:</p>
  <p><a href="https://i.stack.imgur.com/hPEfC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hPEfC.png" alt="Sample" /></a></p>
  <p>I've been able to do a simple skew (moving the corners) but this request is more complex (the bottom half increasingly bends outwards) and I don't quite know where to start.</p>
  <p>Any suggestions would be appreciated.  We may need to hire someone for this project but I need to know what skills to target.</p>
