What it does
Checks if a PDF contains objects to which transfer functions are applied.
Transfer functions are used for creative purposes, artistic effect and to correct the
characteristics of a specific, maybe poorly calibrated, output device. For example,
a file that is intended for output on a particular image setter may contain transfer
functions that compensate for the dot gain inherent to that printer.
Note: Transfer
functions are not allowed in PDF/X compliant
documents.
