folder. Sending it now, incomplete, I need to focus on other things right
now..)
This is nice!
If I may, though, I was looking through your journal of J code, and I just
itch to make "improvements" to it. It's not that it's nonfunctional or
anything, and I'm not even sure if my changes make it faster. And I
certainly have not presented anything with any near your polish - and we
need polish, while my work has tended to look crude and minimalistic -
but...
int2rgb=: [: <. 256 256 256&#:
rgb2int=: [: <. 256&#.@(3&{."1)
You could even make them inverses of one another:
int2rgb=: ([: <. 256 256 256&#:) :.rgb2int
rgb2int=: ([: <. 256&#.@(3&{."1)) :.int2rgb
I'm not sure that this is any more readable. Someone new to J but with a
background in some other computer programming language might be more
comfortable with your expressions than with mine.
Anyways, it's probably worth noting - as you have already done, but I
wanted to emphasize it - that the support code for that video is in the
Journal of J article you linked.
Thanks,
