Hello,

I have an image and a plotted a dot on it. I want to save the dot on the image without borders and axis. This is the code I used. I used saveas before, but it kept a white strip...Thanks!

figure;
image(I)
hold on;
plot(1000,2000,'k.','MarkerSize',40);
end
axis off;
imwrite(I,'output','jpeg');
