[Questions 1 through 8]
I figured out answers to two of my 8 questions and thought I'd share:
#1. > Is there a way, using filters, to take an image A and produce it
photographic negative A', such that 255-C(A)=C(A') for each channel C
in {R,G,B)?
I'm not sure if this is the easiest way, but the following seems to
do it. (at least, adding the result back to the original results in a
monochromatic white rectangle, apparently regardless of the initial image):
<feComponentTransfer>
<feFuncR type="table" tableValues="1 0" />
<feFuncG type="table" tableValues="1 0" />
<feFuncB type="table" tableValues="1 0" />
</feComponentTransfer>
#8 > Does it make sense to submit all these questions as a block or
would it be better to send seven (8?) e-mails to the list?
Anecdotally, it appears the answer is that a block of 8 questions may
be too many all at once. I'll revisit some of the remaining questions
with some more manageable query-rate.
