Grabber::getDisplayFrameFilters Method

Grabber::getDisplayFrameFilters Method

Returns the list of frame filters that are currently set in front of the display.
const tFrameFilterList getDisplayFrameFilters() const;
Return value:

The list of frame filters that are currently set in front of the display, or NULL if neither a list, nor a single frame filter have been set.


The elements in the list are pointers to frame filter objects that are maintained elsewhere. Therefore, these pointers may not be freed. If the method setDisplayFrameFilters was called with a pointer to an IFrameFilter (instead of a list), the list returned by getDisplayFrameFilters has only one element.


Introduced in version 3.0
