title: What in detail is Format32bppPArgb
body: <p><a href="http://msdn.microsoft.com/en-us/library/system.drawing.imaging.pixelformat.aspx" rel="nofollow noreferrer">MSDN</a> says:</p>
  
  <blockquote>
    <p>Format32bppPArgb</p>
    
    <p>Specifies that the format is 32 bits per pixel; 8 bits each are used for the alpha, red, green, and blue components. The red, green, and blue components are premultiplied, according to the alpha component.</p>
  </blockquote>
  
  <p>Does this mean that the RGB values are already multiplied and the A (Alpha) value is not used in real anymore? Does that mean if I have an PARGB <code>ImageFormat</code> used, it is not possible to see the real transparency anymore because the RGB values are already multiplied, or is it only a "nice done" function of GPU where user (developer) does not feel any difference in case of R/G/B result?</p>
