A PDF representation provides a predictable way to embed documents
in mobile and web applications. PDF representations support watermarks
if the original file has been watermarked.PDF representations are generated upon uploading the source file to Box, though
a watermarked PDF is generated upon fetching the watermarked file for
the first time.
To retrieve a watermarked PDF the underlying file itself needs to be
watermarked in Box. You can watermark a file either via the Box web application
or using the PUT /files/:id/watermark/ API.Once watermarked, a watermarked PDF representation of the file is generated.
