Re: Convex Hull Produces Black Image
Yes - when you do the image->Write() function, if you use a .jpg filename, you'll wind up with black images often (or always). If you use .bmp, you'll wind up with usable files/images. And the other person said .png which I haven't personally tried.
.bmp
or
.png
Let us know this solved it.
