Lambda from S3 Bucket

Could I use tracking.js with just image buffer data instead of an img element such that I can use an image file in a s3 bucket to track colors on it using a lambda function?

Start by reviewing tracking.js's current image-input path and determine whether it supports image buffer data instead of an img element. Then investigate the constraints of loading an image from an S3 bucket in a Lambda function. Done would require a confirmed, documented approach or a clearly scoped limitation.
