},示例7: require
import * as Jimp from "jimp";
const _Jimp = require("jimp");
// open a file called "lenna.png"
Jimp.read("lenna.png", (err, lenna) => {
if (err) throw err;
lenna.resize(256, 256) // resize
.quality(60) // set JPEG quality
.greyscale() // set greyscale
.write("lena-small-bw.jpg"); // save
});
// Using promises
Jimp.read("lenna.png")
.then(lenna => {
lenna.resize(256, 256) // resize
.quality(60) // set JPEG quality
.greyscale() // set greyscale
.write("lena-small-bw.jpg"); // save
})
.catch(err => {
console.error(err);
});
// Basic usage
Jimp.read("./path/to/image.jpg", (err, image) => {
// do stuff with the image (if no exception)
});
