.CopyFrom(chno) Copy from channel chno to this channel.

.CopyTo(chno) Copy from this channel to channel chno.

.CornerType(cpno) Input to Output corner type for this control point: 0:smooth, 1:linear. Note that this is different than the KeyType! No implicit frame number argument!

.CP(cpno) The position of control point cpno on the current frame.

.DeleteCP(cpno) Delete control point cpno entirely.

.DeleteCPKey(cpno, mode) Delete the key on control point cpno, with the

given deletion mode: 8=all keys, 4=all past the given frame.

.InsertCP(cpno) Insert a control point before control point cpno.

.isAtDefaults() Whether this Kurve is at its defaults, ie with two fixed control points at 0,0 and 1,1, calling for an identity map (clipped past 1). Note that the saturation channel defaults are 0,1 and 1,1, ie a constant 1.0 factor.

.isCPKeyed(cpno) Whether there is a key on this control point at the current frame.

.isKeyed() Whether there are keys on any control point at the current frame.

.KeyType(cpno) Key type vs frame number for this control point on the current frame: 0:smooth, 1:linear. There should already by a control point key on this frame. Note that this is different than the CornerType! This has an implicit frame number argument!

.NCP() The number of control points on this curve.

.Reset() Reset this kurve back to its defaults, see

.isAtDefaults().

.SetCornerType(cpno, keyt) Set this control point’s corner type. No implicit

frame number argument!

.SetCP(cpno, point) Set a key on the control point cpno on the current frame at the given point location.

.SetKeyType(cpno, keyt) Set this control point’s key type vs frame

number on the current frame. Has an implicit frame number argument!
