Method

GskTransformto_affine

Declaration [src]

void
gsk_transform_to_affine (
  GskTransform* self,
  float* out_scale_x,
  float* out_scale_y,
  float* out_dx,
  float* out_dy
)

Description [src]

Converts a GskTransform to 2D affine transformation factors.

To recreate an equivalent transform from the factors returned by this function, use

gsk_transform_scale (gsk_transform_translate (NULL,
                                              &GRAPHENE_POINT_T (dx, dy)),
                     sx, sy)

self must be a 2D affine transformation. If you are not sure, use

`gsk_transform_get_category()` >= `GSK_TRANSFORM_CATEGORY_2D_AFFINE`

to check.

Parameters

out_scale_x

Type: float*

Return location for the scale factor in the x direction.

The argument will be set by the function.

out_scale_y

Type: float*

Return location for the scale factor in the y direction.

The argument will be set by the function.

out_dx

Type: float*

Return location for the translation in the x direction.

The argument will be set by the function.

out_dy

Type: float*

Return location for the translation in the y direction.

The argument will be set by the function.
