If I use code such as:
fig1 = figure(....);
....
saveas(fig1, 'myfilename.jpg');

The saved file can look terrible because the figure wasn't maximized prior to saving (if you save it after maximising yourself, then it looks fine).

Is there some way I can maximize the figure after creating it so that it saves properly?

Thanks,
Jesse

set(gcf, 'Position', get(0,'Screensize')); % Maximize figure.

Thanks,
That seems to work. However, when I resize my figures (about a dozen of them) before saving, I end up getting a whole bunch of java exceptions which (kind of) crash matlab and definetely make the figures crash.

The problem seems to be that matlab can't keep up with the screen repaint due to the resizing.

The exceptions are:

Sorry, I can't help you with that. The Mathworks might be able to.

When I get stuff like this, it is usually because I have screwed
something up previously.
The best thing to do is to exit from Matlab and start again.
If it happens in a new Matlab session, there is a problem.............
