**NOTE**: The sync & settings commands are admin only! `admin` is a *nick!user@host* mask defined in [scroll.py](https://github.com/ircart/scroll/blob/master/scroll.py)
## Settings
| Setting | Type | Description |
| ---------------- | ------------ | -------------------------------------------------------------------------------------------- |
| `flood` | int or float | delay between each command |
| `ignore` | str | directories to ignore in `.ascii random` *(comma seperated list, no spaces)* |
| `lines` | int | max lines outside of #scroll |
| `msg` | int or float | delay between each message sent |
| `paste` | boolean | enable or disable `.ascii play` |
| `png_brightness` | int or float | increase or decrease brightness for `.ascii img` output |
| `png_contrast` | int or float | increase or decrease contrast for `.ascii img` output |
| `png_effect` | str | change the effect for `.ascii img` output *(blackwhite, blue, greyscale, invert, or smooth)* |
| `png_palette` | str | palette option for `.ascii img` output *(RGB99 or RGB88)* |
| `png_width` | int | maximum width for `.ascii img` output |
| `results` | int | max results to return in `.ascii search` |
**NOTE**: Setting **0** to `png_brightness`, `png_contrast`, or `png_effect` will disable the setting.

## Todo
- git integration to `git clone` the [ircart](https://github.com/ircart/ircart) repository & `git pull` on `.ascii sync` *(Load art files into RAM for faster pumping)*
- `.ascii scroll` command to loop playing random art files *(Stopped with `.ascii stop`)*
- Add arguments to `.ascii img` for contrast, brightness, * effects *(Take them out of self.settings)*
- Add arguments to `.ascii img` for palette, width, & other options
- Setting to auto convert any image link to IRC art *(Emulate link previews like on Discord LOL)*
- `.ascii record` to record lines from the senders nick for uploads *(Stopped with `.ascii stop`)*
- Improve randomness with `.ascii random`

# Scroll IRC Art Bot - Developed by acidvegas in Python (https://git.acid.vegas/scroll)
'''
Pull Request:
- https://github.com/ircart/scroll/pull/3
Props:
- forked idea from malcom's img2irc (https://github.com/waveplate/img2irc)
- big props to wrk (wr34k) for forking this one
- brightness/contrast/effects & more added by acidvegas
Interesting:
- https://pythonexamples.org/pillow-image-blend/
- https://pythonexamples.org/pillow-access-rgb-channels-of-image/
Props:
- forked idea from malcom's img2irc (https://github.com/waveplate/img2irc)
- big props to wrk (wr34k) for forking this + opencv implementation
