virtual bool CanCacheAcrossTransform(bool deltaTrans, bool deltaRot, bool deltaScale) const = 0;
CanCacheAcrossTransform determines whether filters may be able to cache across transformations. However, the ability depends on filter's behavior.
Parameters |
Description |
bool deltaTrans |
True if the translation of the shape has changed since the filter was last cached. |
bool deltaRot |
True if the rotation of the shape has changed since the filter was last cached. |
bool deltaScale |
True if the scale of the shape has changed since the filter was last cached. |
True if the filter can be cached based on the transformation changes, false otherwise
