There is an alternative to having the "colors" component and "opacities" 
component explicitly list the color and opacity associated with each position 
or connection element. If each element of the "colors" and "opacities" 
components is a single byte, then it is interpreted as an 
index into the "color map" or "opacity map" component. The "color 
map" component is a 256-element table of three floating-point values (representing 
red, green, and blue, typically with values between 0 and 1). 
The "opacity map" component is a 256-element table of floating-point values 
between 0 and 1. #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Next Topic #!EF
