Transform.toAffine
void toAffine(out float outScaleX, out float outScaleY, out float outDx, out float outDy)Converts a [gsk.transform.Transform] 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.Transform.getCategory] >= [gsk.types.TransformCategory._2dAffine]
to check.
Parameters
outScaleX | return location for the scale factor in the x direction |
outScaleY | return location for the scale factor in the y direction |
outDx | return location for the translation in the x direction |
outDy | return location for the translation in the y direction |
