Overlay one image over another


I'm trying to overlay 1 image over the top of another but cant seem to work it out - my code throws no errors but doesn't output the requested image modification. Can someone point me in the right direction?

Here is my code

const user = message.mentions.users.first();

if (args[0] === undefined) {
    message.channel.send("You can't jail yourself, dummy!")
} else {
    var images = [user.avatarURL({ format: 'png', dynamic: true, size: 256 }), 'https://i.pinimg.com/originals/7b/51/9a/7b519a3422f940011d34d1f9aa75f683.png']
    var jimps = []
    //turns the images into readable variables for jimp, then pushes them into a new array
    for (var i = 0; i < images.length; i++){
        jimps.push(jimp.read(images[i]))
    }
    //creates a promise to handle the jimps
    await Promise.all(jimps).then(function(data) {
        return Promise.all(jimps)
    }).then(async function(data){
        // --- THIS IS WHERE YOU MODIFY THE IMAGES --- \\
        data[0].composite(data[1], 0, 0) //adds the second specified image (the jail bars) on top of the first specified image (the avatar). "0, 0" define where the second image is placed, originating from the top left corner
        //you CAN resize the second image to fit the first one like this, if necessary. The "100, 100" is the new size in pixels.
        data[1].resize(100,100)

        //this saves our modified image
        data[0].write(`\Users\jmoor\Pictures\JIMP Test\test.png`)
    })
    message.channel.send(`${user.username} has been jailed!`, {file: `\Users\jmoor\Pictures\JIMP Test\test.png`})
}

I have defined jimp above and also am using a command handler I made.


Solution

  • Use this:

        const user = message.mentions.users.first() //get The first user mentioned
        if (!user) return message.reply("Who do you wanna send to jail?")//return if no user was mentioned
        var bars = "https://i.pinimg.com/originals/7b/51/9a/7b519a3422f940011d34d1f9aa75f683.png"
        var pfp = user.avatarURL({ format: 'png', dynamic: true, size: 128 }) //get link of profile picture
        var image = await Jimp.read(pfp)//read the profile picture, returns a Jimp object
        //Composite resized bars on profile picture
        image.composite((await Jimp.read(bars)).resize(128, 128), 0, 0)
        //create and attachment using buffer from edited picture and sending it
        var image = new Discord.MessageAttachment(await image.getBufferAsync(Jimp.MIME_PNG))
        message.reply(image)
