How extract image form output of plot or surf?

I draws some lines in a image with plot in a loop; in each step of loop one line will be drawn. like the following:

figure;imshow(I);hold on; for %% %% outplot = plot(u,v,'b-', 'LineWidth',4); endfor; hold off;

Now i want the final image; is there any solution to use the outplot to have a Independence image or other solution to extract final image.

I have same problem for surf. in the following h = surface(u,v,zeros(h,w),I); output h: h =

Surface with properties:

       EdgeColor: 'none'
       LineStyle: '-'
       FaceColor: 'interp'
    FaceLighting: 'flat'
       FaceAlpha: 1
           XData: [800×1067 double]
           YData: [800×1067 double]
           ZData: [800×1067 double]
           CData: [800×1067×3 uint8]

can I use the output of h (out of surface) to have a image, in the way, i can call it by imshow or imwrite.

Yes, It's work well for plot. Thank you. But, for surf function (as I want to extract the text), the quality is dropped). Could you please give another amazing trick to have Image with same quality for surf function.

Also for the surf, I think the best current way is export_fig to keep the quality safe as possible. Answer link from KSSV . Thank you.
