I have a main figure f with size 1200 x 800 working as my UI. I created another figure f2 of size 512x512 which presents an image:

figure(2)
set(gcf,'units','pixels','position',[500,500,512,512]);
h1 = axes;
set(h1,'position',[0 0 1 1])
set(gca,'XAxisLocation','top','YAxisLocation','left','ydir','reverse');
set (gca, 'visible' , 'off' )
set (gca, 'xtick' , [])
set (gcf, 'color', defaultColor)
axis equal
% Plot some curves
plot(x,y)
% Rasterize
set(gcf, 'InvertHardcopy', 'off')
if ismac || isunix
    img = print(gcf,'-r72','-RGBImage');
elseif ispc
    img = print(gcf,'-r96','-RGBImage');
end
% Show image
imshow(img)

I tried something like this:

ax1 = gca;
copyobj(ax1,f);

This can present the image in f1, but it looks like the image is scaled, that the size is bigger than 512x512. Is there a way to stick f2 to the center of f1 as well as keeping the original size?

Thank you very much!
