  How does the “remove black background” option works?

  Posted by Rihanna Chen on July 9, 2012 at 3:17 am

  This is an amazing software.I am a programmer and I was trying to remove the background of my rendering particles.I tried to divided rgb color by alpha value to get straight alpha,but failed.The result is brighter and lost some details.I used 2 alpha blend modes:
  additive : srcAlpha VS 1
blend : srcAlpha VS 1-srcAlpha
  I guess the additive mode makes the rgba value go unlimited.I wonder if you have met this problem.You said it’s all about rgb value,I really want to know how it works.Any help would be greate thanlful.
