title: Adobe Photoshop 2020 Scripting. ApplyRadialBlur - fourth parameter (object BlurCenter)
body: <p>I think for those who created <strong>Interop.Photoshop.dll</strong> there is a special place in hell.
  Question. I'm trying to change the center of the RadialBlur effect in C#. But I have no idea what and how to transfer parameter there.
  The definition of method says</p>
  <p><code>void ApplyRadialBlur (int Amount, Photoshop.PsRadialBlurMethod BlurMethod, Photoshop.PsRadialBlurQuality BlurQuality, [object BlurCenter])</code></p>
  <p>That is, anything can be passed to the fourth parameter. Because the object keyword is the root of all types.</p>
  <p>In the vbs help (<a href="https://www.adobe.com/devnet/photoshop/scripting.html" rel="nofollow noreferrer">https://www.adobe.com/devnet/photoshop/scripting.html</a>,
  <a href="https://www.adobe.com/content/dam/acom/en/devnet/photoshop/pdfs/photoshop-vbs-ref-2020.pdf" rel="nofollow noreferrer">https://www.adobe.com/content/dam/acom/en/devnet/photoshop/pdfs/photoshop-vbs-ref-2020.pdf</a>) it says</p>
  <p><code>[, BlurCenter]</code> type Number (Double) The parameter BlurCenter is the
  position (unit value).</p>
  <p>WHAT? TO ME? DO? WITH THIS? INFORMATION?</p>
  <p>I spent several hours and so could not find a normal working description of com interface.</p>
