In c# how do I remove the halo from a transparent splash screen
<p>I have a splash screen that is black with white text and a limeGreen background (for transparency key).  </p>

<p>the splash screen is part of a c# project.</p>

<p>the image is very irregular in shape and when i run the splash screen although the transparency works i observe a halo around the outside in limegreen (approx 1px).</p>

<p>what can i do to stop the halo effect?</p>

<p>thanks</p>
