# mklabwall
2+
3+
This is a CLI program to generate wallpapers specifically for `labwc`.
4+
It will generate by default `svg` wallpapers with `#0d1117` background
5+
color with the `labwc` logo and text at `1366 x 768` resolution. Colors,
6+
font family and dimensions can be overridden with the options. `labwc`
7+
icons and text are hard coded.
8+
9+
### build
10+
11+
```
12+
make
13+
14+
# optional as root
15+
16+
make install
17+
```
18+
19+
The binary installs to `/usr/local/bin`. Edit the `Makefile` if you want
20+
to install to an alternate location.
21+
22+
### usage
23+
24+
```
25+
mklabwall
26+
-f font[str]
27+
-s fontsize[int]
28+
-v font_vertical_position[int]
29+
-h font_horizontal_position[int]
30+
-n filename[str]
31+
-z fancy xD [no arg] (an easter egg!)
32+
-b background color["float float float"]
33+
-p save as png [no arg - default is svg]
34+
-l logo only [no arg]
35+
-r resolution ["int int"]
36+
37+
at least 1 option is required
38+
file is saved to "HOME/labwcwall" or "HOME/myfile" with -n [arg] option
39+
Version 0.0.1
40+
```
41+
42+
Images are saved to your `$HOME` directory or any subdir of `$HOME` as
43+
long as that subdir already exists. If it doesn't an error is produced.
44+
45+
The demonstration script `demo.sh` will produce 8 images in `$HOME/demo'
46+
47+
### inspiration
