使用方法
功能介绍
- 图像转ASCII:使用
convertImage(..)
方法将图像转换为ASCII字符。 - FIGlet文本横幅:使用
renderFiglet(..)
方法创建FIGlet风格的文本横幅。 - ASCII到UTF-8字体:使用
renderUnicode(..)

示例代码
以下是一个完整的示例代码,展示了如何使用 enough_ascii_art
插件:
import 'dart:io';
import 'package:enough_ascii_art/enough_ascii_art.dart' as art;
import 'package:image/image.dart' as img;
void main() async {
// 读取并解码图像文件
final bytes = await File('./example/enough.jpg').readAsBytes();
final image = img.decodeImage(bytes)!;
// 将图像转换为ASCII艺术
var asciiImage = art.convertImage(image, maxWidth: 40, invert: true);
print('');
print(asciiImage);
// 将包含表情符号的字符串转换为文本表情符号
var helloWithUtf8Smileys = 'hello world 😛';
var helloWithTextSmileys =
art.convertEmoticons(helloWithUtf8Smileys, art.EmoticonStyle.western);
print('');
print(helloWithTextSmileys);
print('');
// 创建FIGlet风格的文本横幅
print('cosmic:');
var fontText = await File('./example/cosmic.flf').readAsString();
var figure = art.renderFiglet('ENOUGH', art.Font.text(fontText));
print(figure);
print('');
// 将ASCII文本转换为UTF-8字体(双线体)
var unicode = art.renderUnicode('hello world', art.UnicodeFont.doublestruck);
print('double struck:');
print(unicode);
}

安装
在 pubspec.yaml
文件中添加依赖:
dependencies:
enough_ascii_art: ^1.0.0
确保使用最新版本的 enough_ascii_art
,可以通过 Pub 获取最新版本信息。
运行示例
从项目根目录运行示例代码:
dart ./example/enough_ascii_art_example.dart
已知限制
- 图像总是被转换为灰度图。
- FIGlet横幅目前仅支持从左到右的文字方向。
- FIGlet横幅不会自动换行。
- 需要知道具体的FIGlet字体名称(可以在
figlet/fonts
目录中查找)。 - 目前只支持西方风格的表情符号。
如果您有兴趣帮助改进这些限制,请访问 GitHub issue tracker 提交功能请求或报告问题。

当然,以下是如何在Flutter项目中使用enough_ascii_art
插件来生成ASCII艺术的代码案例。enough_ascii_art
是一个Flutter插件,它可以将文本或图像转换为ASCII艺术。
首先,你需要在你的pubspec.yaml
文件中添加依赖项:
dependencies:
flutter:
sdk: flutter
enough_ascii_art: ^最新版本号 # 请替换为实际最新版本号
然后运行flutter pub get
来安装依赖项。
接下来是一个简单的Flutter应用示例,演示如何使用enough_ascii_art
插件:
import 'package:flutter/material.dart';
import 'package:enough_ascii_art/enough_ascii_art.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'ASCII Art Generator',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: AsciiArtScreen(),
);
}
}
class AsciiArtScreen extends StatefulWidget {
@override
_AsciiArtScreenState createState() => _AsciiArtScreenState();
}
class _AsciiArtScreenState extends State<AsciiArtScreen> {
final TextEditingController _controller = TextEditingController();
String _asciiArt = '';
void _convertTextToAsciiArt() async {
String inputText = _controller.text;
try {
String asciiArt = await AsciiArt.textToAsciiArt(inputText);
setState(() {
_asciiArt = asciiArt;
});
} catch (e) {
print('Error converting text to ASCII art: $e');
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('ASCII Art Generator'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
TextField(
controller: _controller,
decoration: InputDecoration(
labelText: 'Enter text',
),
maxLines: 5,
),
SizedBox(height: 16),
ElevatedButton(
onPressed: _convertTextToAsciiArt,
child: Text('Convert to ASCII Art'),
),
SizedBox(height: 16),
Text(
_asciiArt,
style: TextStyle(fontFamily: 'monospace'),
),
],
),
),
);
}
}
在这个示例中,我们创建了一个简单的Flutter应用,用户可以在输入框中输入文本,然后点击按钮将文本转换为ASCII艺术。转换后的ASCII艺术会显示在下方的文本区域中。
TextField
用于接收用户输入的文本。ElevatedButton
用于触发文本到ASCII艺术的转换。_convertTextToAsciiArt
方法调用AsciiArt.textToAsciiArt
进行转换,并更新状态以显示生成的ASCII艺术。
请确保你已经在pubspec.yaml
中添加了enough_ascii_art
的依赖,并且已经运行了flutter pub get
。如果你遇到任何问题,请检查enough_ascii_art
的最新版本和API文档,因为插件的API可能会随时间发生变化。
