Hi, I set my figure as below:
However, the popped figure window has resolution 1024x1024. When I try to get the result as a matrix:
F = getframe (gcf,[0,0,512,512]);
[img, ~] = frame2im (F);
I would like to get img with resolution 512x512x3, but I get its value as 1024x1024x3.
Is there anyway to solve this problem?

Thank you all ! I think it is a problem of macos, when explicitly setting '-r72' or '-r96' for different os, the problem is solved.
