Syntax:

virtual bool getTransformOutputTypes( const FrameTypeInfo& in_type,
                                      FrameTypeInfoArray& out_types ) const = 0;

Return Value:

Value Description

true The list with supported output types was filled.

false No transformation available.

Remarks:

The types should be ordered, depending upon the preference of the transform operation. The output type of this transform filter will be chosen based on the capabilities and input preference of the next filter and this filter.

When you override checkTransformTypes, this method is not called unless you call it in your own implementation.
