Jimp: How get buffer of converted Image

[vignestion]

hi
Is that possible to get Buffer of converted Image.I've tried it but it return null

let ImageURI = req.body.data.thumbnailBlob;

    let buf = new Buffer(ImageURI.replace(/^data:image\/\w+;base64,/, ""),'base64');

    Jimp.read(buf,(err,image) => {
       if(err) {
           console.log(err)
       }
       image.cover(250,250)
           .getBuffer( "image/jpeg",(Buff) => {
               console.log(Buff)//null
           })
    })

@githubitsme Same issue here, how did you managed to overcome this situation?

Edit:

Since I always work with promises, I forgot to include in the callback parameters error and result:

image.getBuffer(Jimp.MIME_PNG, (error, result) => ...

the null is because no erro was found.

Hope help some absent minded like me :)
