How to change quality for an image using the base64 encode ?

Hello,

Could you please help me with a JSON example on how to add the quality parameter for an image using the new base 64 encoding?

I've tried

{ edits: { quality: 50, } bucket: 'test', key: 'test.jpg', }

and

{ edits: { resize: { quality: 50, } } bucket: 'test', key: 'test.jpg', }

@rapgodnpm I am moving this to the Discussions/Q&A as it is more appropriate in that section

Quality changes are associated with the image format and the following is the correct way to specify it in a request.

This was tested using quality values of 100 and 50. The results can be compared using Preview on Mac with Tools->Adjust Color.

The color palette that appears shows a difference between the two along with the returned image file size being smaller for lesser quality values.

const imgReq = JSON.stringify({
    bucket: 'test',
    key: 'test.jpg',
    edits: {
        resize: {
            width: 1000,
            height: 500
        },
        jpeg: {
            quality: 100
        }
    }
});

const encStr = Buffer.from(imgReq).toString('base64');
const imageUrl = `https://api.cloudfront.net/${encStr}`;
console.log(imageUrl);

Yes, it works if I put

webp: {
  quality: 50
}

Thank you very much for your help and patience, you saved my day.
