Question

我正在从APICA中收集一些数据,我希望在APIC图像负荷之前使用图像的模糊。我如何能够做到这一点? 我可以在网上找到任何辅导。

BlurHash拍摄了一个图像,给你一个短幅(仅20-30个字眼!)来代表这一形象的持有人。你在你工作的背后这样做,并照图像储存插图。

这方面的一个例子是:

import  package:flutter/material.dart ;
import  package:flutter_blurhash/flutter_blurhash.dart ;

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title:  Flutter Demo ,
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const BlurHashApp(),
    );
  }
}

class BlurHashApp extends StatelessWidget {
  const BlurHashApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) => MaterialApp(
        home: Scaffold(
          appBar: AppBar(title: const Text("BlurHash")),
          body: const SizedBox.expand(
            child: Center(
              child: AspectRatio(
                aspectRatio: 1.6,
                child: BlurHash(
                  // hash was generated when you upload the image and returned along with image url by backend
                  hash: "LKN]Rv%2Tw=w]~RBVZRi};RPxuwH",
                  image: "https://blurha.sh/ea9e499f8080ce9956a8.jpg",
                ),
              ),
            ),
          ),
        ),
      );
}

当你上载图像时,便会产生散射。

How? There are several implementation:

For example with python:
