%% MOVIESLIDER Embeddable panel for playback, scrolling, and contrast/color map adjustment of 3D movies.
%
% This software depends on the GUI Layout Toolbox:
% http://www.mathworks.com/matlabcentral/fileexchange/47982-gui-layout-toolbox
% Make sure to get the version appropriate for your version of Matlab (R2014b onwards vs. older).
%
% The class MovieSlider creates a panel (that can be embedded like any other uix object) that
% displays the current frame of the movie tensor provided by the user, which is assumed to be
% 3-dimensional where the first two dimensions comprise a frame and the third dimension indexes a
% particular frame in the movie. GUI and keyboard controls allow automatic playback/looping as well
% as live scrolling through frames. There is also a button to cycle through contrast settings, and
% an extended configuration panel where the user can fine-tune the playback speed, color map and
% mapping range.
%
% Example usage:
% shape = normpdf(-2.5:0.05:2.5, 0, 1);
% tensor = bsxfun(@times, bsxfun(@times, shape, shape'), reshape(shape,1,1,[]));
% movie = MovieSlider(tensor);
%
% Example of additional graphics drawn per frame:
% hMark = line('Parent', movie.axsMovie, 'XData', [], 'YData', [], 'LineWidth', 2, 'Color', [1 1 1], 'Marker', 'o', 'MarkerSize', 8);
% time = ( 0:size(tensor,3) )'; values = [size(tensor,2)/2 + 40*sin(time/5), size(tensor,1)/2 + 40*cos(time/8)];
% movie.addIllustrations(hMark, {'XData', 'YData'}, num2cell(values));
%
% Various member functions exists for programatic control of some features:
% show(...) : Sets the currently displayed movie (can also be done at
% construction time)
% setPlaybackFPS(playbackFPS) : Set playback rate in frames per second
% setTitle(string) : Sets the current title, or removes it if an empty string is
% provided; a cellstring can also be provided to show a different
% title per frame
% setFrame(index) : Sets the current frame to the given index
% setFocusReturn(fcnReturn) : Sets the function to call upon an 'escape' keypress
