Uploading canvas image to S3 through ember uploader

I was using ember uploader to upload file to S3. Now, I have a use case where I need to upload CANVAS image to S3. In this case, I don't have a file but just the image data

"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAASwAAAEsCAYAAAB5fY51AAAgAEl>EQVR4Xu1dd7xUxfU/r/fOoxd77y3GmFhiNFGsARtFEKQoTRFsKFhQsdAsgEoTEAUsWJNoEn9RY4nGEmLsUl7h8frj9bfl9zmz7LJ735Z7Z+/dvbN85x/.........."

Is there a way of doing this through ember uploader?
