Grabber::getDeviceFrameFilters Method |
||
| Returns the list of frame filters that are currently set behind the device. | ||
| Syntax: | const tFrameFilterList getDeviceFrameFilters() const; |
|
| Return value: | The list of frame filters that are currently set behind the device, or NULL if no list nor a single frame filter has been set. |
|
| Remarks: | 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 setDeviceFrameFilters was called with a pointer to a IFrameFilter (instead of a list), the list returned by getDeviceFrameFilters has only one element. |
|
| Information: | Introduced in version 3.0 | |
