# img2irc (1.0.6)
![img2irc preview](https://i.imgur.com/oetHhMB.png)

img2irc is a utility which converts images to half or quarterblock irc/ansi art, with a lot of post-processing filters

*halfblock* means that each row will contain two rows worth of pixels, effectively doubling the vertical resolution

*quarterblock* (experimental) means that each row will contain two rows worth of pixels, and each column will contain two columns worth of pixels, quadrupling the resolution

the `irc` mode has 99 colours, the `ansi` mode has 256, `ansi24` has 16777216
