clipRegion
- specifies the clip regionpublic void clearClipRgn(Region clipRegion) throws StdQTException
clipRegion
- specifies the clipping region to clear. This must correspond to all
or part of a previously set clip region.public void setClipState(boolean clipEnable) throws StdQTException

- if true clipping is enabled, otherwise it is disabled.public boolean getClipState() throws StdQTException
public DigitizerInfo getDigitizerInfo() throws StdQTException
public int getInputFormat(int input) throws StdQTException
input
- The input video source for this request. Video digitizer components number video sources sequentially, starting at 0. So, to request
information about the first video source, an application sets this parameter to 0. Applications can get the number of video sources supported by a
video digitizer component by calling getNumberOfInputs ().public void setInputStandard(int input) throws StdQTException
input
- the input signaling standard. (ntscIn, palIn, secamIn)
