图像大小

获得图像的高度和宽度 图像 浏览器中的 api 和 缓冲图像大小 数据包在节点.

安装

# npm
npm install @coderosh/image-size

# yarn
yarn add @coderosh/image-size

使用量

• 图像源作为 url (nodejs 和浏览器)

  import imageSize from '@coderosh/image-size'
  
  const main = async () => {
    const url = 'https://ulka.js.org/logo.png'
  
    const size = await imageSize(url)
    console.log(size) // { height: 827, width: 738 }
  }
  

• 作为阵列缓冲器的图像源( 节点和浏览器)

  import imageSize from '@coderosh/image-size'
  
  const main = async () => {
    const url = 'https://ulka.js.org/logo.png'
    const ab = await fetch(url).then((res) => res.arrayBuffer())
  
    const size = await imageSize(ab)
    console.log(size) // { height: 827, width: 738 }
  }
  

• 图像源作为缓冲( 只有节点)

  import imageSize from '@coderosh/image-size'
  
  const main = async () => {
    const url = 'https://ulka.js.org/logo.png'
    const buffer = await fetch(url).then((res) => res.buffer())
  
    const size = await imageSize(buffer)
    console.log(size) // { height: 827, width: 738 }
  }
  

• 图像源为 blob( 仅浏览器)

  import imageSize from '@coderosh/image-size'
  
  const main = async () => {
    const url = 'https://ulka.js.org/logo.png'
    const blob = await fetch(url).then((res) => res.blob())
  
    const size = await imageSize(blob)
    console.log(size) // { height: 827, width: 738 }
  }
