I try to make my own linear:

Code: Select all

function linear(input,fromMin,fromMax,tooMin,tooMax){
	input = Math.min(input,fromMax);
	input = Math.max(input,fromMin);
	var y = (((tooMax-tooMin)/(fromMax-fromMin))*(input-fromMin))+tooMin;
	return y;
}

but have to test it...

There are two possibilities for using these functions:
1) write a temporary expression and retrieve the value (preExpression flag set to false). Easy to code but slow execution (ok for computing few values)
2) port these Expression functions to pure JavaScript that a script will understand. Some of them are easy to implement, some require more effort (especially the layer space transform, still doable though ). Obviously the way to go in case of many function calls.
