Transform2dToAffineElements Method |
Gets the six coefficients used by the traditional 2d drawing APIs as an
array in (a, b, c, d, tx, ty) order.
Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)
Since: 9.0
SyntaxRemarks
Those APIs map a point (x,y) to (a*x + c*y + tx, b*x + d*y + ty), so the
six values are the transpose of the Transform2d value order: a is M00,
b is M10, c is M01, d is M11, tx is M02 and ty is M12. Composition order
is reversed as well, because those APIs use the row vector convention:
A2d * B2d is the equivalent of the platform product B * A.
