Maybe I'm doing something with jit.expr that I'm not supposed to, but
can someone explain the result of this little patch?
It prints out "0 0 0 0" in the max window when you press the bang
button. I would expect that using a constant in jit.expr would
output that constant, not 0. I'm not saying that this is a bug, but
it's what I would expect jit.expr to do in this case.
In the end, what I'd like to do is replace everything in a few
specific planes of an incoming matrix with a constants. I just
wanted a simple patch that created a "noisy" hue along very specific
lines, and held the saturation and luminosity of the video constant,
but due to the problem (or my misunderstanding) above, it doesn't
work that way I'd like:
