.. realign .. _internal_realign: Re-Align Image ============== Many times a plot from an old PDF or report contains images that are rotated or distorted in the photo-copy process. In order to realign the axes and make them orthogonal, use the ``Fix-Image-Alignment`` option. 3 and 4 Point Alignment ----------------------- The images below, for example, need to be realigned before they can be digitized. The image on the left has 4 distinct corners that can be used to realign the axes. The image on the right, has only 3 distinct points. Under the menu option ``Fix-Image-Alignment``, you can choose ``4 Point Axes Align`` or ``3 Point Axes Align`` as appropriate. .. raw:: html
