Scale and shape parameters of Gamma mixture distributions

Marine Regis 
Hello,


I used the function "mix" (package "mixdist'') to fit Gamma mixture distributions. The function gives mu and sigma parameters (output below). How can I find the scale and shape parameters of the Gamma distributions ?


Parameters:
      pi    mu sigma
1 0.2089 185.7 285.4
2 0.7911 530.1 423.5


Thanks a lot for your time.
