# imgtools
Some random image-related tools. Usually they are drop-in
replacements where possible.
## iconv
Converts a Plan 9 image from one format to another. For example,
`iconv -c rgb16 <a.img >b.img` will convert `a.img` to RGB16 and save
it as `b.img`.
"Channels" (`-c` argument) are defined at `/sys/include/draw.h:133`.
`rgb16`, `RGB16`, `r5g6b5` and `R5G6B5` mean the same thing
(case-insensitive).
## resample
A faster drop-in replacement of `resample(1)` with some more features.
