MATLAB: How to save the content of the current figure as an image

Question

how to save the content(which is an image) of the current figure as an image?

I have about 30 figure …

I want to use MATLAB commands to save them in for loop

Answer 1

saveas(gcf,'filename.png')

would also work.

or something like this

for i=1:30
  % code to show image number i
  saveas(gcf,['filename' num2str(i) '.png']);
end

if you don't like the border around it type:

iptsetpref('ImshowBorder','tight');

before preparing your figure.
