Find middle point between distances in photoshop
So in photoshop if I have a picture of a head, and I want to make a line from the top of the head to the bottom of the head, how do I display the middle of that line? The ruler tool doesn't have an option to mark the center.
Is there any program that has that simple option? I just want to draw a line and have it mark the center.
EDIT: All great suggestions. Additionally, you can use Marquee tool and just press ctrl + t after you draw a box and it will show the center temporarily.
I use following techique in Illustrator and Photoshop:
Draw a straight path, copy the path, and rotate by 90 degrees. Since the rotation pivot is by default in the middle you get a cross that achieves exactly what you want. This has the advantage of also working for arbitrary angles. More importantly this can be recorded as a action and applied to many paths at once with just a keypress if you find yourself doing this alot.
Also if i remember correctly (need to check when i go home atleast it works for rotation) when you measure a distance it puts that value in the move dialog you can then divide by 2 or even 3, to get a precice move from end to any division.
