bPoint¶
Description¶
The bPoint
is a point object which mimics the old “Bezier Point” from RoboFog. It has attributes for bcpIn
, anchor, bcpOut and type. The coordinates in bcpIn and bcpOut are relative to the position of the anchor. For instance, if the bcpIn is 20 units to the left of the anchor, its coordinates would be (-20,0), regardless of the coordinates of the anchor itself. Also: bcpIn will be (0,0) when it is “on top of the anchor”, i.e. when there is no bcp it will still have a value. The parent of a bPoint is usually a Contour
.

Transformations¶
-
BaseBPoint.
transformBy
(matrix, origin=None)¶ Transform the object.
>>> obj.transformBy((0.5, 0, 0, 2.0, 10, 0)) >>> obj.transformBy((0.5, 0, 0, 2.0, 10, 0), origin=(500, 500))
matrix must be a Transformation Matrix. origin defines the point at with the transformation should originate. It must be a Coordinate or
None
. The default is(0, 0)
.
-
BaseBPoint.
moveBy
(value)¶ Move the object.
>>> obj.moveBy((10, 0))
value must be an iterable containing two Integer/Float values defining the x and y values to move the object by.
-
BaseBPoint.
scaleBy
(value, origin=None)¶ Scale the object.
>>> obj.scaleBy(2.0) >>> obj.scaleBy((0.5, 2.0), origin=(500, 500))
value must be an iterable containing two Integer/Float values defining the x and y values to scale the object by. origin defines the point at with the scale should originate. It must be a Coordinate or
None
. The default is(0, 0)
.
-
BaseBPoint.
rotateBy
(value, origin=None)¶ Rotate the object.
>>> obj.rotateBy(45) >>> obj.rotateBy(45, origin=(500, 500))
value must be a Integer/Float values defining the angle to rotate the object by. origin defines the point at with the rotation should originate. It must be a Coordinate or
None
. The default is(0, 0)
.
-
BaseBPoint.
skewBy
(value, origin=None)¶ Skew the object.
>>> obj.skewBy(11) >>> obj.skewBy((25, 10), origin=(500, 500))
value must be rone of the following:
- single Integer/Float indicating the value to skew the x direction by.
- iterable cointaining type Integer/Float defining the values to skew the x and y directions by.
origin defines the point at with the skew should originate. It must be a Coordinate or
None
. The default is(0, 0)
.
Environment¶

naked
()¶ Return the environment’s native object that has been wrapped by this object.
>>> loweLevelObj = obj.naked()

BaseBPoint.
changed
(*args, **kwargs)¶ Tell the environment that something has changed in the object. The behavior of this method will vary from environment to environment.
