@notriddle Functioned perfectly.
For my understandings. The function overay in the module imageops don’t have a return value, rather the function takes the two image-objects/reference and change the img-variable within his function?
My fault was i have handle imageops like image::save.
In the https://docs.rs/image/0.21.1/image/imageops/fn.overlay.html i don’t can read that i need the img-variables (I stand for image-object?) but i can now see it has no return value and wtf yes top and bottom are the layers. Hmm very hard to understandable.
image::imageops::overlay is also an static class, thats what i understand, but i hope in the next time i will more undertand strage new rust mechanism.
What are the difference between .function and ::function the path in the modules? Sorry my head burns a bit:).
