to_affine


Description:

public void to_affine (out float out_scale_x, out float out_scale_y, out float out_dx, out float out_dy)

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)

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

get_category >= gsk_transform_category_2d_affine

to check.

Parameters:

this

a `GskTransform`

out_scale_x

return location for the scale factor in the x direction

out_scale_y

return location for the scale factor in the y direction

out_dx

return location for the translation in the x direction

out_dy

return location for the translation in the y direction
