fine uploader - How to modify current chunk data during upload process with FineUploader -

we need call third party lib, ideally @ time of onuploadchunk callback. shown in documentation (http://docs.fineuploader.com/branch/master/api/events.html#uploadchunk), can have parameters in order identify chunk , stuff javascript slice method.

but, question : how give updated chunk fineuploader upload process ?

thanks lot help.

you cannot modify chunks created fine uploader, nor should able may change size of chunk, expected total number of chunks, , require adjustments of internal state , sent parameters. if you'd modify files, have 2 options:

1. modify file before sent to fine uploader
2. modify file before file upload begins. can cancel original file, , submit changed versions via the addfiles api method.
