Class API¶

class wx.GraphicsMatrix(GraphicsObject)¶

A GraphicsMatrix is a native representation of an affine matrix.

Methods¶

Concat(self, t)¶

Concatenates the matrix passed with the current matrix.

The effect of the resulting transformation is to first apply the transformation in t to the coordinates and then apply the transformation in the current matrix to the coordinates.

# matrix = t * matrix

Parameters:

t (wx.GraphicsMatrix) – The parameter matrix is the multiplicand.

Return type:

None

---

Get(self)¶

Returns the component values of the matrix via the argument pointers.

Return type:

Tuple[float, float, float, float, float, float]

---

GetNativeMatrix(self)¶

Returns the native representation of the matrix.

For CoreGraphics, this is a CFAffineMatrix pointer, for GDI+ a Matrix Pointer, and for Cairo a cairo_matrix_t pointer.

Return type:

Any

---

Invert(self)¶

Inverts the matrix.

Return type:

None

---

IsEqual(self, t)¶

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

Parameters:

t (wx.GraphicsMatrix)

Return type:

bool

---

IsIdentity(self)¶

Return True if this is the identity matrix.

Return type:

bool

---

Rotate(self, angle)¶

Rotates this matrix clockwise (in radians).

This can be useful for applying a tilt to your drawing commands or for drawing radial patterns.

Parameters:

angle (wx.Double) – Rotation angle in radians, clockwise.

Return type:

None

DegToRad

---

Scale(self, xScale, yScale)¶

Scales this matrix.

Parameters:

• xScale (wx.Double)

• yScale (wx.Double)

Return type:

None

---

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

Sets the matrix to the respective values (default values are the identity matrix).

Parameters:

• a (wx.Double)

• b (wx.Double)

• c (wx.Double)

• d (wx.Double)

• tx (wx.Double)

• ty (wx.Double)

Return type:

None

---

TransformDistance(self, dx, dy)¶

Applies this matrix to a distance (i.e., performs all transforms except translations).

Parameters:

• dx (wx.Double)

• dy (wx.Double)

Return type:

Tuple[float, float]

---

TransformPoint(self, x, y)¶

Applies this matrix to a point.

Parameters:

• x (wx.Double)

• y (wx.Double)

Return type:

Tuple[float, float]

---

Translate(self, *args, **kw)¶

Overloaded Implementations:

---

Translate (self, dx, dy)

Translates this matrix.

Parameters:

• dx (wx.Double)

• dy (wx.Double)

Return type:

None

---

Translate (self, pt)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters:

pt (wx.Point2D)

Return type:

None

Added in version 4.3/wxWidgets-3.3.0.
