img2irc (1.0.4)

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
