Class API

class GraphicsMatrix(GraphicsObject)

A matrix holds an affine transformations, such as a scale, rotation, shear, or a combination of these, and is used to convert between different coordinate spaces.

Methods

__init__(self)

Initialize self. See help(type(self)) for accurate signature.

---

Clone(self)

---

Concat(self, matrix) → Self

Concatenates the matrix passed with the current matrix.

---

Get(self)

Return the component values of the matrix as a tuple.

---

GetNativeMatrix(self)

---

Invert(self) → Self

Inverts the matrix.

---

IsEqual(self, matrix)

Returns True if the elements of the transformation matrices are equal.

---

IsIdentity(self)

Returns True if this is the identity matrix.

---

Rotate(self, angle) → Self

Rotates the matrix in radians

---

Scale(self, xScale, yScale) → Self

Scale the matrix

---

Set(self, a=1.0, b=0.0, c=0.0, d=1.0, tx=0.0, ty=0.0)

Set the components of the matrix by value, default values are the identity matrix.

---

TransformDistance(self, dx, dy)

Applies this matrix to a distance (ie. performs all transforms except translations.)

---

TransformPoint(self, x, y)

Applies this matrix to a point and returns the result

---

Translate(self, dx, dy) → Self

Translate the matrix. This shifts the origin.
