A wx.GraphicsMatrix is a native representation of an affine matrix. The contents are specific and private to the respective renderer. The only way to get a valid instance is via a CreateMatrix call on the graphics context or the renderer instance.

Method Details

Concat(self, t)

Concatenates the passed in matrix to the current matrix.

Parameters:
t
           (type=GraphicsMatrix)

Get(*args, **kwargs)

Get(self) --> (a, b, c, d, tx, ty)

Gets the component values of the matrix and returns them as a tuple.

GetNativeMatrix(self)

Returns the native representation of the matrix. For CoreGraphics this is a CFAffineMatrix pointer. For GDIPlus a Matrix Pointer and for Cairo a cairo_matrix_t pointer. NOTE: For wxPython we still need a way to make this value usable.

Returns:
void

Invert(self)

Inverts the matrix.

IsEqual(self, t)

Returns True if the elements of the transformation matrix are equal

Parameters:
t
           (type=GraphicsMatrix)

Returns:
bool

IsIdentity(self)

Returns True if this is the identity matrix

Returns:
bool

Rotate(self, angle)

Rotates this matrix. The angle should be specified in radians.

Parameters:
angle
           (type=Double)

Scale(self, xScale, yScale)

Scales this matrix.

Parameters:
xScale
           (type=Double)

yScale
           (type=Double)

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 specified values (default values are the identity matrix.)

Parameters:
a
           (type=Double)

b
           (type=Double)

c
           (type=Double)

d
           (type=Double)

tx
           (type=Double)

ty
           (type=Double)

TransformDistance(*args, **kwargs)

TransformDistance(self, dx, dy) --> (dx, dy)

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

TransformPoint(*args, **kwargs)

TransformPoint(self, x, y) --> (x, y)

Applies this matrix to a point, returns the resulting point values

Translate(self, dx, dy)

Add a translation to this matrix.

Parameters:
dx
           (type=Double)

dy
           (type=Double)
