you could have skipped this step by disabling error diffusion.
the bugs section of iconv(1) mentions this.
i think the main problem with the current error diffusion is that
the scan always goes from left to right. a simple fix might be to
alternate the scan from left-to-right then right-to-left. also, the
error diffusion needs to be extended beyond 3 color channels
(for example, to b&w).
perhaps i don't understand the problem properly, but i think it
might make sense to remove the error diffusion from jpg and friends
and add it to iconv.
