Knot types. One of the following values:
KTYPE_AUTO
- This type of knot generates the
bezier handles automatically to produce a smooth curve. With this
knot type the bezier handles are invisible.KTYPE_CORNER
- This knot type produces a sharp
corner.KTYPE_BEZIER
- This knot type produces bezier
handles that are collinear (the bezier vectors coming out of the
knot are collinear). These handles are constrained to be collinear
so if the user moves one handle the other will move to remain
collinear. Also if the user moves the handle towards or away from
the knot the other handle will move the corresponding amount in the
proper scale.KTYPE_BEZIER_CORNER
- This knot
type has bezier handles but they are not constrained to be opposite
each other.
