[GEM-dev] pix_hit

[B. Bogart]

Hi!

This sounds cool, but I'm a little confused.

I'm guessing your testing for white pixels that happen to become visible
within the pix in the correct region?

If this is right then you feed it pix_motion for motion hits, and
pix_background for "presence" hits?

sounds cool...
