Hi, I am making a GUI that can browse image from directory and load it on an axes (and the user can rotate the image). I need to add a vertical line at the center of the image (preferably using button). But I am really lost here as I am new at MATLAB. So far, I can only make a GUI that can browse image and show it on an axes, and user can already rotate it using slider. Please tell me what to do to add the line using button. (Btw, I was trying to put my code here but it came out messy, anyone knows why?) Thanks a lot

For formatting tutorial, read this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup Basically paste, highlight, then click {}Code.
To draw a line on your image:
hold on;
[rows, columns, numberOfColorChannels] = size(yourImage);
midColumn = columns/2;
line([midColumn, midColumn], [1, rows], 'Color', [.8, .7, 0.1]);
You can change the color and location if you want.

After the user double clicks the line to accept it, you have to decide if you want to draw a line into the overlay or burn it into the image. I attach a demo that goes over all that. If I've answered all your questions, can you mark the answer as "Accepted"?
