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.
