# 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
|
|
|
