BOOL PVideoOutputDeviceRGB::SetFrameSize ( unsigned  width,
unsigned  height 
) [virtual]

Set the frame size to be used.

Note that devices may not be able to produce the requested size, and this function will fail. See SetFrameSizeConverter().

Default behaviour sets the frameWidth and frameHeight variables and returns TRUE.
