frame2im - Return image data associated with movie frame

Syntax

[X,Map] = frame2im(F)

Description

[X,Map] = frame2im(F) returns the indexed image X and associated colormap Map from the single movie frame F. If the frame contains true-color data, the MxNx3 matrix Map is empty. The functions getframe and im2frame create a movie frame.

Example

Create and capture an image usinggetframe and frame2im:

peaks                      %Make figure
f = getframe;              %Capture screen shot
[im,map] = frame2im(f);    %Return associated image data 
if isempty(map)            %Truecolor system
  rgb = im;
else                       %Indexed system
  rgb = ind2rgb(im,map);   %Convert image data
end
