Its very very simple, read the image by >> imread (). provided your image is in work. Than make a mask of same size as your image of all zeros (White). Now make a line in that white mask. eg >> image_name(10,20:30) = 1 ; Line will be of black color and your mask is of white color.

Simply add this mask having black line with your origional image. and see the result.

Yes you have done.

Good Luck
