RSTransform class Null safety

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({required double rotation, required double scale, required double anchorX, required double anchorY, required double translateX, required double translateY})
Creates an RSTransform from its individual components.

Properties

hashCode int
The hash code for this object.

runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
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.
