It also includes a full working .capx for you to study.
this is sort of helping thank you,
i am however trying to make 1 jigsaw peace = 1 pic so i can add another pic into a new jigsaw peace and then join the 2 pics together.
I am not worried about the peaces snapping together as they should all have the same mask on.
i can not seem to be about to break this code down into a way to understand the process .
thank you.
