title: Which is faster, GDI+ or libpng?
body: <p>I have an <code>HBITMAP</code> and I would like to convert it to png format(in memory I have malloc'd)as fast as possible, so my question is should I go with <code>GDI+</code> or <code>libpng</code>?</p>
  
  <p>I've tried using <code>GDI+</code>, but it doesn't seem as fast as I would like it to be.
  I've also tried <code>FreeImage</code> and it was way too slow.</p>
