Depth to point node

Here is what i am doing,

I have a clean green screen alpha pulled and am wanting to emit particles from a rototed part of this alpha.

so i did a shuffle of the alpha top depth.

then dropped in a depthToPoint node using the depth.z from the shuffle. and i get a clean point cloud but there is a lot of extra points blasting out behind the alpha in z. so when i do a emit from points i get tons of extra particles behind the character.

can i crop points? what are all of these extra points from?

i even just did a roto circle and depthToPoints from that and i get the same exact thing... hmm

i believe it could be because of the edge of the alpha has some transparent pixels so the depth is converting that to different "depths" through the shuffle.

how do i make every pixel 100% white i guesss would be my question.
