Question

我已使用此代码从图像文件中读取文本。 Reading text from image

代码如下

from PIL import Image
from pytesseract import image_to_string

image = Image.open("image.jpg",'r')

myText = image_to_string(Image.open(open('maxresdefault.jpg')),config='-psm 10')
myText = image_to_string(Image.open(open('maxresdefault.jpg')))
print(myText)

错误：UnicodeDecodeError：'charmap'编解码器无法解码位置278中的字节0x81：字符映射到

尝试通过以下方式解决此错误：UnicodeDecodeError: 'charmap' codec can't decode byte X in position Y: character maps to <undefined>

然后得到错误：

UnicodeDecodeError：'utf-8'编解码器无法解码位置0的字节0xff：无效的起始字节

Answer 1

根据Image文档（help(Image.open)），必须以二进制模式打开图像文件：

open('maxresdefault.jpg', 'rb')

Answer 2

以二进制格式加载图像。

更改以下代码为我解决了这个问题。

import 'package:flare_flutter/flare_actor.dart';
import 'package:flutter/material.dart';
import 'package:travelbrains/models/story.dart';

class AnimationPlayer extends StatefulWidget {
  static const String id = 'AnimatedPlayer';
  final Story story;

  AnimationPlayer(this.story);

  @override
  _AnimationPlayerState createState() => _AnimationPlayerState();
}

class _AnimationPlayerState extends State<AnimationPlayer> {
  String animPath;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Animation Test'),
      ),
      body: FlareActor(
        widget.story.animationRef.toString(),
//      "assets/flare.flr",
        alignment: Alignment.center,
        fit: BoxFit.contain,
        animation: 'myAnim',
      ),
    );
  }
}

希望有帮助！
