Transform

gsk.transform.Transform is an object to describe transform matrices.

Unlike graphene.matrix.Matrix, gsk.transform.Transform retains the steps in how a transform was constructed, and allows inspecting them. It is modeled after the way CSS describes transforms.

gsk.transform.Transform objects are immutable and cannot be changed after creation. This means code can safely expose them as properties of objects without having to worry about others changing them.

Functions

equal bool equal(gsk.transform.Transform second): Checks two transforms for equality.
getCategory gsk.types.TransformCategory getCategory(): Returns the category this transform belongs to.
invert gsk.transform.Transform invert(): Inverts the given transform.
matrix gsk.transform.Transform matrix(graphene.matrix.Matrix matrix): Multiplies next with the given matrix.
perspective gsk.transform.Transform perspective(float depth): Applies a perspective projection transform.
print void print(glib.string_.String string_): Converts self into a human-readable string representation suitable for printing.
rotate gsk.transform.Transform rotate(float angle): Rotates next angle degrees in 2D - or in 3D-speak, around the Z axis. The rotation happens around the origin point of (0, 0).
rotate3d gsk.transform.Transform rotate3d(float angle, graphene.vec3.Vec3 axis): Rotates next angle degrees around axis.
scale gsk.transform.Transform scale(float factorX, float factorY): Scales next in 2-dimensional space by the given factors.
scale3d gsk.transform.Transform scale3d(float factorX, float factorY, float factorZ): Scales next by the given factors.
skew gsk.transform.Transform skew(float skewX, float skewY): Applies a skew transform.
to2d void to2d(float outXx, float outYx, float outXy, float outYy, float outDx, float outDy): Converts a gsk.transform.Transform to a 2D transformation matrix.
to2dComponents void to2dComponents(float outSkewX, float outSkewY, float outScaleX, float outScaleY, float outAngle, float outDx, float outDy): Converts a gsk.transform.Transform to 2D transformation factors.
toAffine void toAffine(float outScaleX, float outScaleY, float outDx, float outDy): Converts a gsk.transform.Transform to 2D affine transformation factors.
toMatrix void toMatrix(graphene.matrix.Matrix outMatrix): Computes the actual value of self and stores it in out_matrix.
toString_ string toString_(): Converts a matrix into a string that is suitable for printing.
toTranslate void toTranslate(float outDx, float outDy): Converts a gsk.transform.Transform to a translation operation.
transform gsk.transform.Transform transform(gsk.transform.Transform other): Applies all the operations from other to next.
transformBounds void transformBounds(graphene.rect.Rect rect, graphene.rect.Rect outRect): Transforms a graphene.rect.Rect using the given transform self.
transformPoint void transformPoint(graphene.point.Point point, graphene.point.Point outPoint): Transforms a graphene.point.Point using the given transform self.
translate gsk.transform.Transform translate(graphene.point.Point point): Translates next in 2-dimensional space by point.
translate3d gsk.transform.Transform translate3d(graphene.point3_d.Point3D point): Translates next by point.

Static functions

parse bool parse(string string_, gsk.transform.Transform outTransform): Parses the given string into a transform and puts it in out_transform.
