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.
__init__(self)¶Clone(self)¶Concat(self, matrix)¶Concatenates the matrix passed with the current matrix.
Get(self)¶Return the component values of the matrix as a tuple.
GetNativeMatrix(self)¶Invert(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)¶Rotates the matrix in radians
Scale(self, xScale, yScale)¶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)¶Translate the matrix. This shifts the origin.
