How can I save an image with fixed x and y limits?
In the specific I want to save an image with x limits -0.4 - 0.4 and y limits -0.4 - 0.4.
But when I save the image the limits are bigger.
plot(camera.Points(:,1),camera.Points(:,2),'rx','marker','o','color','white','MarkerSize',size,'MarkerFaceColor','k');
axis([-.4 .4 -.4 .4]);
set(gca,'Color','black','XTickLabel',[],'YTickLabel',[]);
set(gca,'visible','off');
daspect([1 1 1]);
hfig = figure;
hax_new = copyobj(hax, hfig);
set(hax_new, 'Position', get(0, 'DefaultAxesPosition'));
saveas(gcf,fullfile('../Data/img',sprintf('/Image%04d.jpg', i)));

What is hax? If it is a known axes then why are you using gca?

sorry, hax is
hax = subplot(1,2,2);
.. the subplot that I want to save. Now I corrected gca with hax but it doesn't work.
