Description:

[ Version ( since = "1.0" ) ]
public unowned Matrix? init_from_2d (double xx, double yx, double xy, double yy, double x_0, double y_0)

Initializes a Matrix from the values of an affine transformation matrix.

The arguments map to the following matrix layout:

  ⎛ xx  yx ⎞   ⎛  a   b  0 ⎞
  ⎜ xy  yy ⎟ = ⎜  c   d  0 ⎟
  ⎝ x0  y0 ⎠   ⎝ tx  ty  1 ⎠
sed to convert between an affine matrix type from other libraries and a Matrix.

Parameters:

this

xx

the xx member
yx

the yx member
xy

the xy member
yy

the yy member
x_0

the x0 member
y_0

the y0 member

Returns:

the initialized matrix
