On right click of the mouse a horizontal line has to be drawn, this way any number of line should be drawn on one image, also the exact location of the mouse click should be shown as pixels in a text box, for ex: 348, and by left click of the mouse on the line, the line should should be dragged up/down on the image with the corrosponding pixels shown in the text box, also the text box should be editable for eg if we input a number on the text box the horizontal line should be moved to the new location.
