Re: Multiple Value2dDisplay's on a single Raster

[Parviez HosseiniC]

Rather than using multiple Value2dDisplays, wouldn't the thing to do be add 
some code like

currValue =[myDiscrete2d getValueAtX:x Y:y];
[myDiscrete2d  putValue: (myValue+currValue) X:x Y:y];


and have forest, grass, lakes, use same display, just different values?
That way zeroes are transparent, and you could do some double checking 
when you want to turn lakes into trees?
