Electron主进程使用imagemin、imagemin-gifsicle压缩gif图片

安装

npm install imagemin@7.0.1
npm install imagemin-gifsicle@7.0.0
安装时要注意下两者之间的版本。（imagemin的8.0.0版本是ES6模块化）

使用

const imagemin = require('imagemin')
const imageminGifsicle = require('imagemin-gifsicle')

// fileAbPath: 图片的路径数组 D:/image/a.gif
// outPath: 输出路径，输出文件名与原文件名一致
// colors: 压缩后图片的颜色值， 值越小图片大小就越小 2~256
async compressGifImg({ fileAbPath, outPath = 'D:/min', colors = 64 }) {
  console.log('compressGifImg', fileAbPath, outPath, colors)
    try {
      const files = await imagemin([fileAbPath], {
        destination: outPath,
        glob: false,
        plugins: [
          imageminGifsicle({
          optimizationLevel: 3,
          colors
        })
      ]
    })
    console.log('compress success')
    return files
  } catch (error) {
      console.log(error)
  }
 }

如果想把某个目录下的gif全部压缩：glob传true,图片路径使用通配符

async compressGifImg({ fileAbPath: 'D:/image/*.gif', outPath = 'D:/min', colors = 64 }) {
  console.log('compressGifImg', fileAbPath, outPath, colors)
    try {
      const files = await imagemin([fileAbPath], {
        destination: outPath,
        glob: true,
        plugins: [
          imageminGifsicle({
          optimizationLevel: 3,
          colors
        })
      ]
    })
    console.log('compress success')
    return files
  } catch (error) {
      console.log(error)
  }
 }
