GetFrame


Capture Movie Frame
Syntax


GetFrame
F = GetFrame
F = GetFrame (h)
F = GetFrame (h,rect)

Description


GetFrame returns a movie frame. The frame is a snapshot (pixmap) of the current axes or figure.

F = GetFrame Gets a frame from the current axes.

F = GetFrame (h) Gets a frame from the figure or axes identified by handle H.

F = GetFrame (h,rect) specifies a rectangular area from which to copy the Pixmap. Rect is relative to the lower left corner of the figure or axes h, in pixel units. Rect is a four-element vectors in the form [left bottom width height], where width and height define the dimensions of the Rectangle.

frame2im-return image data associated with movie frame Syntax

[X,map] = Frame2im (F)
Description

[X,map] = Frame2im (F) returnsthe indexed ImageX and associated ColorMap Map fromthe single movie frame F. If the frame containstrue-color data, Them-by-n-3matrix Map is empty. The functions getframe andim2frame Createa movie frame. Examples

Create and capture an image using GetFrame 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
