Saving an image with no gui

I'm trying to run a program in the background that periodically checks an archive for % completion and then creates a figure of some progress bars that I made. Everything works fine when I run it through the gui, but this is part of a much larger workflow than I'm setting up and having the gui run is just not an option. I need to run it in the background, and right now I'm using the command

$MATLAB/bin/matlab -nodisplay -nosplash -nodesktop

from my mac terminal.

Now, the problem is, when I run the program in this way, when I go to save the figure, it only grabs a small 560x420 rectangle in the middle, however, from the gui it grabs the full image (I forget exactly what it is, but it's 3-4k on the long side). I really want this to save the whole image both ways, but I don't know why this is happening. Below is how I'm saving the figure, for reference.

    h = figure(1);
    set(h,'OuterPosition', [0, 0, 1680, 1050])

Other code for filling figures

    set(h, 'PaperPositionMode', 'auto')
    saveas(h,'/Users/johnsalter/Dropbox/KeplerMaster/Progressbars','png')

Any ideas?

Hello! Ten years later, I have this exact problem, except I was already using "print" instead of "saveas". As John said, this doesn't solve the problem. Anyone have any ideas now? One difference for me is I am using linux. Also, honestly, the most likely scenario here is that I go on to investigate this myself and post an answer when I figure it out, but in case anyone who knows a lot about print and/or nodisplay mode glances at this comment before I finish, I would appreciate the time-saver

Have you tried exportgraphics() or copygraphics(), available with r2020a or later?

I have not, I will look into those, thanks! If they work, I'll let you know.

Hi Steven,

Maybe this peace of code will help you. I used this code to save images without showing/plotting them, because I also wanted to run the script in the background or server side open remote window, though on Windows machines....

figure, imshow(<yourimage>),
set(gca, 'position', [0 0 1 1], 'visible', 'off') 
% hold on  % optional
% text(10,10,<'yourtext'>, <more props to set>,'');
% hold off
I = getframe(gcf);
I=frame2im(I);
fullname=sprintf('%s/%s',<yourpath>,<yourfilename>);
imwrite(I,fullname,'Quality',100);

Success,

Quattro

Use print instead of saveas.

it saves it as a little bigger than saveas but still not the whole image
