Method
GskTransformto_2d
Declaration [src]
void
gsk_transform_to_2d (
  GskTransform* self,
  float* out_xx,
  float* out_yx,
  float* out_xy,
  float* out_yy,
  float* out_dx,
  float* out_dy
)
Description [src]
Converts a transform to a 2D transformation matrix.
self must be a 2D transformation. If you are not
sure, use
`gsk_transform_get_category()` >= GSK_TRANSFORM_CATEGORY_2D
to check.
The returned values are a subset of the full 4x4 matrix that
is computed by gsk_transform_to_matrix() and have the
following layout:
  | xx yx |   |  a  b  0 |
  | xy yy | = |  c  d  0 |
  | dx dy |   | tx ty  1 |
This function can be used to convert between a GskTransform
and a matrix type from other 2D drawing libraries, in particular Cairo.
Parameters
- out_xx
- 
            Type: float*Return location for the xx member. The argument will be set by the function. 
- out_yx
- 
            Type: float*Return location for the yx member. The argument will be set by the function. 
- out_xy
- 
            Type: float*Return location for the xy member. The argument will be set by the function. 
- out_yy
- 
            Type: float*Return location for the yy member. The argument will be set by the function. 
- out_dx
- 
            Type: float*Return location for the x0 member. The argument will be set by the function. 
- out_dy
- 
            Type: float*Return location for the y0 member. The argument will be set by the function.
