Method

GskTransformto_2d_components

Declaration [src]

void
gsk_transform_to_2d_components (
  GskTransform* self,
  float* out_skew_x,
  float* out_skew_y,
  float* out_scale_x,
  float* out_scale_y,
  float* out_angle,
  float* out_dx,
  float* out_dy
)

Description [src]

Converts a GskTransform to 2D transformation factors.

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

gsk_transform_skew (
    gsk_transform_scale (
        gsk_transform_rotate (
            gsk_transform_translate (NULL, &GRAPHENE_POINT_T (dx, dy)),
            angle),
        scale_x, scale_y),
    skew_x, skew_y)

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

`gsk_transform_get_category()` >= `GSK_TRANSFORM_CATEGORY_2D`

to check.

Available since:4.6
