createRotateMatrix
createRotateMatrix(
angle
,pivotPoint
?):TMat2D
Generate a rotation matrix around around a point (x,y), defaulting to (0,0)
A matrix in the form of [cos(a) -sin(a) -xcos(a)+ysin(a)+x] [sin(a) cos(a) -xsin(a)-ycos(a)+y] [0 0 1 ]
Parameters
• angle: TRotateMatrixArgs
= {}
rotation in degrees
• pivotPoint?: Partial
<XY
> = {}
pivot point to rotate around
Returns
matrix
