ramp maximum value

[Tranguz]

Sorry, a novice question about ramps. I was trying to get the maximum value of a ramp (Spline Ramp) with an expression using Python. How do i cycle between ramp points?

ramp.eval() returns an object containing keys and values, so along this line:

ramp = node.parm("myramp").eval()
maximum = max(ramp.values())
for x in range(len(ramp.keys())):
    print ramp.keys()[x]
    print ramp.values()[x]

etc.

hth,

skk.

Oh Thanks for your help SYmek. Now I got it!

So eval() method in hou.Parm class with a referenced ramp parameter doesn't give you a int, float, or str value but an instance of hou.Ramp from which I can easily obtain the maximum ramp value from the values() tuple!

Thanks a lot!
