I'm generating movies using
mov = addframe(mov,fig);
where fig is a handle to a figure.

I've also tried to do this with
mov = addframe(mov,getframe(fig));
but this causes the same problem.

The text is placed on top of a rectangle() which is placed on top of an imagesc(). This is done with text(...'Interpreter','latex').

The rough text appears not just in the output file, but also on the screen.

I'm using 2009b on a MacPro.

I've used the latex interpreter on simpler figures before, and not had this problem. Will try to recreate it with simple code, but the current code is very complex. I have posted a screen shot here:

The text is in the bottom left corner of the plot box, in white.

Please let me know if you have any ideas.

Thanks.
Rich

The text will get jagged when the figure's renderer property is set to
zbuffer or OpenGL. Try setting it to 'painters':

set(gcf,'Renderer','painters')

The problem is that this will be slow if the number of points in your
image is large, but it should look better.

This doesn't work. It was also suggested here:
http://www.mathworks.com/matlabcentral/newsreader/view_thread/125018

In fact, 'painters' is the default renderer.

Richard,

Did you actually change the renderer after producing the figure? I ask
because sometimes what you graph will change the renderer without you
being aware of it. It doesn't matter what the default is.

If you are explicitly changing the renderer to painters and you still
get bitmapped latex text then see if you can produce a minimal example
that exhibits this behavior and post it. I'd be interested to see what
happens here.

OK, Doug,

you are correct that the renderer can change unexpectedly.

using the code:

set(gcf,'Renderer','painters'); drawnow;
mov = addframe(mov,getframe(fig));

to make a movie actually seems to fix the problem. That's great.

However,

set(gcf,'Renderer','painters'); drawnow;
mov = addframe(mov,fig);

still has the same problem.

I can work with the first formulation, but the second is more convenient. Do you have any further suggestions?

Many thanks.
