dealing with ramp using python

[mohamaedkamal]

hello everyone , 

I want to add multiple ramp points using python any one can help to achieve that 

[f1480187]

# Initialize new ramp.
node = hou.pwd()
ramp_parm = node.parm('ramp')

bases = [hou.rampBasis.Linear] * 5
keys = [0.0, 0.125, 0.25, 0.375, 0.5]
values = [0.0, 0.25, 0.5, 0.75, 1.0]
ramp = hou.Ramp(bases, keys, values)

ramp_parm.set(ramp)

# Add multiple points to existing ramp.
node = hou.pwd()
ramp_parm = node.parm('ramp')

ramp = ramp_parm.eval()
bases = list(ramp.basis()) + [hou.rampBasis.Constant] * 4
keys = list(ramp.keys()) + [.5, 0.625, 0.75, 0.875]
values = list(ramp.values()) + [0.25, 0.5, 0.75, 1.0]
ramp = hou.Ramp(bases, keys, values)

ramp_parm.set(ramp)

# Change first point value from 0.0 to 1.0.
node = hou.pwd()
point1_val = node.parm('ramp1value') # Point indexing starts from 1.
point1_val.set(1.0)

thanks for the example, very easy to set up a ramp parameter with python
