Params

• String|Buffer source: The path/url to the image or a Buffer object.
• Object|String options: The path to the image or an object containing the following fields:

Size Options:

• pxWidth (Number): The pixel width used for aspect ratio (default: 2).
• size (Object): The size of the result image (ASCII art)
  • height (Number|String): The height value (default: "100%").
  • width (Number|String): The width value (default: computed value to keep aspect ratio). This is optional if the height is provided.
  • screen_size (Object): The screen size (defaults to terminal width and height):
    • width (Number): The screen width.
    • height (Number): The screen height.
  • px_size (Object): The pixel size.
    • width (default: 1)
    • height (default: 1)
  • preserve_aspect_ratio (Boolean): If false, the aspect ratio will not be preserved (default: true).
  • fit_screen (Boolean): If false, the result size will not fit to screen (default: true).

Matrix asciifier options:

• stringify (Boolean): If false, the pixel objects will not be stringified.
• concat (Boolean): If false, the pixel objects will not be joined together.

Pixel asciifier options:

• pixels (Array|String): An array or string containing the characters used for converting the pixels in strings (default: " .,:;i1tfLCG08@").
• reverse (Boolean): If true, the pixels will be reversed creating a negative image effect (default: false).
• colored (Boolean): If true, the output will contain ANSI styles (default: true).
• bg (Boolean): If true, the background color will be used for coloring (default: false).
• fg (Boolean): If true, the foreground color will be used for coloring (default: true).

• px_background (Object): An object containing the r (red), g (green) and b (blue) values of the custom background color.

Other options:

• image_type (String): Use this to explicitely provide the image type.
• stringify_fn (Function): A function getting the pixels matrix and the options in the arguments. Use this option to implement your own stringifier.
• Function callback: The callback function.
