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

RSTransform(double scos, double ssin, double tx, double ty)
Creates an RSTransform. [...]
RSTransform.fromComponents({double rotation, double scale, double anchorX, double anchorY, double translateX, double translateY })
Creates an RSTransform from its individual components. [...]

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.
read-only
hashCode int
The hash code for this object. [...]

runtimeType Type
