##U8glib package
Ported from https://github.com/olikraus/u8glib
Here is black magic with ImageMagic package for image conversion:
```
bash
#!/bin/bash
mkdir
out
for
icon
in
*
png
;
do
convert
$icon
-depth
1 ./out/
$(
basename
$icon
.png
)
_1bpp.png
if
[[
"
$icon
"
==
*
"black"
*
]]
;
then
convert ./out/
$(
basename
$icon
.png
)
_1bpp.png
-background
white
-alpha
Background ./out/
$(
basename
$icon
.png
)
_1bpp.xbm
else
convert ./out/
$(
basename
$icon
.png
)
_1bpp.png
-background
black
-alpha
Background ./out/
$(
basename
$icon
.png
)
_1bpp.xbm
fi
cat
./out/
$(
basename
$icon
.png
)
_1bpp.xbm |
tr
'\n'

tr

" "
|sed

'#^.*{##g'

'#,}##'
|sed s
'/;//'

-r
-p
>
./out/
$(
basename
$icon
.png
)
.xbm.mono
done
rm
out/
*
png out/
*
xbm
```
Convert all the png in the current folder and put resulting .mono to ./out
The convert binary is a part of ImageMagic package. You need to install it.
```
sudo apt-get install imagemagick
```
for Debian/Ubuntu.
