RSTransform class
A transform consisting of a translation, a rotation, and a uniform scale.
Used by Canvas.drawAtlas. This is a more efficient way to represent these simple transformations than a full matrix.
Constructors
Properties
- scos → double
-
The cosine of the rotation multiplied by the scale factor.
read-only
- ssin → double
-
The sine of the rotation multiplied by that same scale factor.
read-only
- tx → double
-
The x coordinate of the translation, minus scos multiplied by the
x-coordinate of the rotation point, plus ssin multiplied by the
y-coordinate of the rotation point.
read-only
- ty → double
-
The y coordinate of the translation, minus ssin multiplied by the
x-coordinate of the rotation point, minus scos multiplied by the
y-coordinate of the rotation point.
