%% Capture Axes Plus 30 Pixel Border % Capture the interior of an axes plus a margin of 30 pixels in each % direction. % Copyright 2015 The MathWorks, Inc. %% Can't embed yet % Create a plot of random data. plot(rand(5)) %% % Change the axes units to pixels and return the current axes position. The % third and fourth elements of the position vector specify the axes width % and height in pixels. set(gca,'Units','pixels') pos = get(gca,'Position') %% % Create a four-element vector, |rect|, that defines a rectangular area % covering the axes plus the desired margin. The first two elements of % |rect| specify the lower-left corner of the rectangle relative to the % lower-left corner of the axes. The last two elements of |rect| specify % the width and height of the rectangle. marg = 30; rect = [-marg, -marg, pos(3)+2*marg, pos(4)+2*marg]; F = getframe(gca,rect); %% % Use |imshow| to display the captured image data. %% Embed this section figure imshow(F.cdata)
