ANSIR

Build Status

Generate UTF-8 Art from PNG using ANSI color codes.

Similar to oldschool ANSI art, we use UTF-8 block characters and standard terminal color escape sequences.

Supports both the basic and extended ANSI color escape sequences. Note: Full 24-bit RGB escape sequences currently not supported.

A utility conv.js can be used to convert JPEGs etc to PNG format.

Installation

  1. npm install -g ansir

Generate artwork

  1. ansir sample/in.png

Proportionally rescale the png file on the fly

  1. ansir --scale 0.1 sample/in.png > sample/out.ans

Renderers

Ansir supports 3 modes of rendering, shown in the following table:

Usage

  1.   Usage: ansir <png>
  3.   Generate UTF-8 Art from PNG using ANSI color codes.
  5.   Options:
  7.     -h, --help                 output usage information
  8.     -s, --scale <float>        Proportionally rescale image
  9.     -w, --width <integer>      Target output width (in characters)
  10.     -h, --height <integer>     Target output height (in lines)
  11.     --colors <basic|extended>
  12.         The ANSI colorspace. Use "basic" for the most compatible 8-color
  13.         palette. The default is "extended" for the 256-color palette supported by
  14.         most major terminals that have any color at all.
  15.     --background <light|dark>
  16.         Applies only to "shaded" mode. Specifies whether the target terminal
  17.         will have a light or dark background. This determines color matching for
  18.         shaded UTF-8 block characters. Default is "dark", which means we interpret
  19.         a shaded block character as darker than a solid one.
  20.     --alpha-cutoff <float>
  21.         The minimum alpha value of a pixel that should be converted to a ansi
  22.         color utf-8 block character. Valid values are 0.0-1.0. Default is
  23.         0.95.
  24.     --mode <block|shaded|sub>
  25.         The rendering mode. Default is "block". The options are:
  27.         "block" - Use the ANSI background escape sequence to create seamless blocks.
  29.         "shaded" - Use the ANSI foreground escape sequence on unicode block character.
  30.           ░ LIGHT SHADE
  31.           ▒ MEDIUM SHADE
  32.           ▓ DARK SHADE
  33.           █ FULL BLOCK
  35.         "sub" - Use the ANSI foreground escape sequence on unicode quadrant block
  36.                 characters. NOTE: These characters can cause slowness when used
  37.                 with some common terminal fonts such as Consolas.
  38.           ▘ QUADRANT UPPER LEFT
  39.           ▝ QUADRANT UPPER RIGHT
  40.           ▖ QUADRANT LOWER LEFT
  41.           ▗ QUADRANT LOWER RIGHT
  42.           ▚ QUADRANT UPPER LEFT AND LOWER RIGHT
  43.           ▞ QUADRANT UPPER RIGHT AND LOWER LEFT
  44.           █ FULL BLOCK
