I have an image consisting of a black background and white foreground pixels. I want to know the shortest distance from one white pixel to another white pixel on a path constrained to only touch white pixels.<div><br></div>
<div>As an example, if the image is of the outline of a circle, the distance from a point on the circle to a point directly across the diameter should be half of the circumference, rather than the diameter.<br clear="all">
<br></div><div>Is there something built in to do this?</div><div><br></div><div>Thanks,<br><br>David<br>
