MATLAB: Can I include an AVI-file in the HTML-file generated by using “Publish to HTML” toolbar button in MATLAB

I have a MATLAB script that creates a movie. I would like to include this movie in the HTML document created by "Publish to HTML" or the PUBLISH command.

The ability to include AVI-files in the HTML-file generated by the PUBLISH command is not currently available in MATLAB. To work around this issue, you can modify your HTML-file manually to include an AVI file (created using MOVIE2AVI) that shows your movie. To do this, follow these steps:

1. Create an AVI file using MOVIE2AVI. Place this file in the "html" subdirectory created when you used the "Publish to HTML" option. (The subdirectory will be in the same directory as the original MATLAB file that you published.)

2. Open the MATLAB-generated HTML-file with the MATLAB Editor/Debugger or another text editor. This file will be in the "html" subdirectory and will have the same name as the original program file, but with the extension ".html" instead of ".m".

3. Find the place where the movie command appears in the HTML. After the "movie(...)" text, there will be an image in the HTML which contains the last frame of the movie. Remove the "image" tags and everything in between.

4. In the spot in the HTML-file where the image was, add an AVI object to the HTML-file using the "object" tag, as in:

 <object data="mymovie.avi" type="video/avi">
 Text to Display if the Browser Doesn't Support AVI files.
 </object>

This will include the AVI file in your HTML-file. Please note that many browsers do not support AVI objects, and the security options in your browser may also prevent the display of AVI objects.

MATLAB: How to copy an image of an axes without including the entire figure

Consider a simple figure with tabular and plotted data:

f = figure;
x = [1;2;3];
y1 = [1;2;3];
y2 = [1;3;5];
t = uitable(f,'Data',[x y1 y2],'ColumnName',{'x','y1','y2'},'RowName',{},'Units','normalized');
t.Position = [.03 .65 t.Extent(3:4)];
ax = axes('Position',[.5 .1 .45 .8]);
plot(x,[y1 y2]);
legend({'y1','y2'});

Here are three ways to copy an image of just the axes to the clipboard:

1. Hover your mouse over the axes and a toolstrip will appear at the top right corner. Hover over the leftmost icon and then select "Copy as image". This will copy an image of your axes to the clipboard exactly as is (including both plot and legend). If you cannot see the axes toolbar, make sure its "Visible" property is set to "on":

2. To achieve this programmatically, create a new empty figure and use "copyobj" to move a copy of just the axes into the new figure. You can then use "hgexport" or "print" as before.

https://www.mathworks.com/help/matlab/ref/copyobj.html

For example,

f2 = figure;
copyobj(ax,f2);
hgexport(f2,'-clipboard');

3. Another programmatic solution is to use 'ScreenCapture', a File Exchange pick of the week. This code can copy images of figures - as well as specific components within a figure - to the clipboard.

More information can be found on this blog post:

https://blogs.mathworks.com/pick/2012/08/10/grab-a-screen-shot-from-within-matlab/

For this example, you can take a screencapture of the axes without even copying the object into a new figure.Please note that this function is user-submitted, so it is not officially supported or checked for bugs.

MATLAB: How to play movies at a size different from the original using the MOVIE function within MATLAB

The ability to play an AVI-file of a specified size using the MOVIE function is not available in MATLAB.

To work around this issue, try resizing your AVI-file before using the MOVIE function. For example:

First, create a sample movie.

t = linspace(0,2*pi,40);
fact = 10*sin(t);
fig=figure;
set(fig,'DoubleBuffer','on');
mov = avifile('example.avi','compression','indeo5','fps',8)
[x,y,z] = peaks;
for k=1:length(fact)
      h = surf(x,y,fact(k)*z);
      axis([-3 3 -3 3 -80 80])
      axis off
      caxis([-90 90])
      F = getframe(gca);
      mov = addframe(mov,F);
end
close(fig)
mov = close(mov);

Second, resize the sample movie.

% read in the movie
mov = aviread('example.avi');
% reduce the movie by 2
factor = 2;
% get dimensions of example.avi
dims = size(mov(1).cdata);
% scale axes, flip ydir for IMAGE, set units to pixels
hf = figure;
ha = axes( ...
      'units','pixels', ...
      'position',[0 0 dims([2 1])./factor], ...
      'nextplot','replacechildren', ...
      'ydir','reverse');
axis(ha,'off');
% create new movie
newmov = avifile('newexample.avi','compression','none');
for i=1:length(mov)
      % display movie frame by frame on resized axis
      image(mov(i).cdata);
      axis(ha,'tight')
      % add frame to new movie
      newmov = addframe(newmov,getframe(ha));
end
% create new movie file
newmov = close(newmov);
