rotate method

void rotate(
  1. double degrees
)

Rotates the current transformation matrix by the given angle in degrees.

Rotation is performed around the current origin (0,0) of the transformed coordinate system.

  • degrees: The angle of rotation in degrees.

Implementation

void rotate(double degrees) {
  final c = cosDegree(degrees);
  final s = sinDegree(degrees);
  transform(c, s, -s, c, 0.0, 0.0);
}
