Transition Class
Reference
#include <xsi_transition.h>
This object represents a transition between two clips. A transition is an interpolation used to smooth passing from the end of one clip to the beginning of another.
You can get at the Transition object from the ClipContainer::GetTransitions function. Calling SIObject::GetType on the Transition object returns one of the strings defined under the siTransitionType.

| bool IsA | ( | siClassID | in_ClassID | ) | const [virtual] |
Returns true if a given class type is compatible with this API class.

| Transition& operator= | ( | const Transition & | in_obj | ) |
Creates an object from another object. The newly created object is set to empty if the input object is not compatible.
| in_obj | constant class object. |
| Transition& operator= | ( | const CRef & | in_ref | ) |
Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.
| in_ref | constant class object. |
Reimplemented from ProjectItem.
| Clip GetStartClip | ( | ) | const |
Returns the clip at the beginning of the Transition.
| Clip GetEndClip | ( | ) | const |
Returns the clip at the end of the Transition.
| CRefArray GetItems | ( | ) | const |
Returns the channels which are used in this transition. The channels are the objects for which the value is interpolated, common objects retrieved with MappedItem::GetDestination.
