Member Function Documentation

bool ColorPallet::checkColorModel (  const string &  str  )  [private]
 

Look for a color model = string and set the type.

Parameters:
offset must be between 0 and 255
r,g,b,a Return the red, green, blue, and alpha value for offset. Values are [0..1]
Returns:
false if there was trouble. For example a bad offset
