Extending IPP to fit SEAL System Needs¶
Header File Format¶
PLOSSYS 4.x header files have the following format:
$ PLS_PLOTTER == pdfout
$ PLS_COPIES == 1
Header Attributes for IPP¶
The IPP standard allows to define a new OPERATION-KEYWORD.
SEAL Systems uses the OPERATION-KEYWORD seal-attributes to send header attributes.
The values in seal-attributes are encoded as PLS_KEY=VALUE and are sent in IPP stream to the target system.
The target system has to parse the IPP stream, read the seal-attributes one by one
and separate PLS_KEY and VALUE after the first = sign.
