    %% Configure Pixel Stream Format
% When you choose a standard video format for |visionhdl.FrameToPixels|,
% the object computes the frame dimensions. To access these values, call the
% |getparamfromfrm2pix| function. 
frm2pix = visionhdl.FrameToPixels(...
      'NumComponents',1,...
      'VideoFormat','240p');
[activePixels,activeLines,numPixelsPerFrame] = getparamfromfrm2pix(frm2pix)
%%
% Note that |numPixelsPerFrame| includes both active and inactive
% regions of the frame.
