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
`halfblock` mode increases the vertical resolution, doubling the total resolution for a given size
*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
`quarterblock` mode increases both the vertical and horizontal resolution by twofold, quadrupling the total resolution for a given size
the `irc` mode has 99 colours, the `ansi` mode has 256, `ansi24` has 16777216
`braille` mode uses 2x4 dot patterns to represent pixels, increasing resolution eightfold
`irc` mode has 99 colours, (6.62-bit)
`ansi` mode has 256 colours (8-bit)
`ansi24` has 16777216 colours (24-bit)
