충분한 아스키 예술

An ASCII art library for Dart developers.

Available under the commercial friendly MPL Mozilla License 2.0.

Usage

Things you can do with enough_ascii_art:

• Generate a textual representation of an image using convertImage(..).
• Create FIGlet text banners with renderFiglet(..).
• Convert ASCII text into UTF-8 "fonts" like 𝕕𝕠𝕦𝕓𝕝𝕖 𝕤𝕥𝕣𝕦𝕔𝕜 with renderUnicode(..).
• Convert common UTF-8 emoticons to their text-representation with convertEmoticons(..).

Usage example:

import 'dart:io';
import 'package:enough_ascii_art/enough_ascii_art.dart' as art;
import 'package:image/image.dart' as img;

void main() async {
  final bytes = await File('./example/enough.jpg').readAsBytes();
  final image = img.decodeImage(bytes)!;
  var asciiImage = art.convertImage(image, maxWidth: 40, invert: true);
  print('');
  print(asciiImage);

  var helloWithUtf8Smileys = 'hello world 😛';
  var helloWithTextSmileys =
      art.convertEmoticons(helloWithUtf8Smileys, art.EmoticonStyle.western);
  print('');
  print(helloWithTextSmileys);
  print('');

  print('cosmic:');
  var fontText = await File('./example/cosmic.flf').readAsString();
  var figure = art.renderFiglet('ENOUGH', art.Font.text(fontText));
  print(figure);
  print('');

  var unicode = art.renderUnicode('hello world', art.UnicodeFont.doublestruck);
  print('double struck:');
  print(unicode);
}

The above code renders the following output:

%%%%%%%%%%%%%%%%%%@%@%#%#%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%##      -@%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%.        .#%%%%%%%%%%%
%%%%%%%%%%%%%%%%%#          #%%%%%%%%%%%
%%%%%%%%%%%%%%%%#@           %%%%%%%%%%%

Contribute & Known Limitations

Any contributions are welcome!

Known limitations:

• Images are always converted to grayscale
• The FIGlet banners are currently only supported with left-to-right text direction
• The FIGlet banners are not wrapped into multiple lines
• You cannot list all available FIGlet fonts, but instead need to know their names (check out the figlet/fonts directory!)
• Currently only western style text emoticons are available

Please help removing these limitations!
