No. If you want to "burn" the data points into the image without using saveas() or export_fig() then you'll have to do it manually via a for loop as you suggest, though it's not hard and should be fast.
Saving image with a plot in a variable.

I have some image 'I' and a plot of y vs x. I overlay the plot on 'I' as follows
imshow(I); hold on; plot(x,y); hold off;
I would like to save this image with the plot in a "variable". How can I do that? I don't want to save it in a file using saveas option.
There can be more ways of plotting a graph on "I" like running a 'for' loop through size(x) and setting I(y,x)=1. Are there any short methods to achieve this.
Thanks
