gamma ramp must contain integer elements

[Shih-Yu Lo]

hi
I just installed python 2.6, VisionEgg, and all those required modules. When I ran my program, I specified the Gamma value to 2.1, and it said: "gamma ramp must contain integer elements". Below is the information from the log file:

So how should I fix this?
