ASCII Renderer

A command line application to convert an image to ASCII art.

Usage

From the project directory:

dart run bin/ascii_renderer.dart --input input.jpg --output output.txt --cols 80 --contrast 1.0

• --input defaults to input.jpg
• --output defaults to output.txt
• --font defaults to assets/font/iosevka.png
• --char_ratio defaults to 1 2 (1x2 width by height ratio of the font characters)
• --cols defaults to 240
• --contrast defaults to 1.0 (1.0 is normal, >1.0 = sharper edges)
• --charset defaults to ascii (possible values: ascii, extended, cp437)
• --help prints the same options.

TODO List

• Fix font used for classification (arial does not fully support CP437)
• Generate native executable.
• Add command line flags to provide input and output paths at runtime.
• Add command line flags to customize ASCII character sets to use: basic, extended, cp437.
• Decide whether to add color output
• Check out Dart argument parsing libraries to use
• Option for no file output
