Makes a new TransformState with the specified components.
Returns the inverse of this transform.
Makes a new 2-d TransformState with the specified components.
If you are going to immediately compose this result with another TransformState, it is faster to do it in one operation with invert_compose(). Returns the pointer to the unique TransformState in the cache that is equivalent to this one. This may be the same pointer as this object, or it may be a different pointer; but it will be an equivalent object, and it will be a shared pointer. This may be called from time to time to improve cache benefits. Returns the union of the Geom::GeomRendering bits that will be required once this TransformState is applied to a geom which includes the indicated geom_rendering bits. The RenderState's get_geom_rendering() should already have been applied. Overrides this method to update PStats appropriately. Overrides this method to update PStats appropriately. Overrides this method to update PStats appropriately. Overrides this method to update PStats appropriately. Returns the number of entries in the composition cache for this TransformState. This is the number of other TransformStates whose composition with this one has been cached. This number is not useful for any practical reason other than performance analysis. Returns the number of entries in the invert_composition cache for this TransformState. This is similar to the composition cache, but it records cache entries for the invert_compose() operation. See get_composition_cache_num_entries(). Returns the number of slots in the composition cache for this TransformState. You may use this as an upper bound when walking through all of the composition cache results via get_composition_cache_source() or result().
This has no practical value other than for examining the cache for performance analysis. Returns the source TransformState of the nth element in the composition cache. Returns NULL if there doesn't happen to be an entry in the nth element. See get_composition_cache_result().
This has no practical value other than for examining the cache for performance analysis. Returns the result TransformState of the nth element in the composition cache. Returns NULL if there doesn't happen to be an entry in the nth element.
In general, a->compose(a->get_composition_cache_source(n)) == a->get_composition_cache_result(n).
