F.2.1 Header (Part 1)
The Linearized PDF file begins with the standard header line (see Section 3.4.1,
applied to any PDF file of version 1.1 or greater.
The binary characters following the percent sign on the second line are characters
with codes 128 or greater, as recommended in Section 3.4.1, “File Header.”
F.2.2 Linearization Parameter Dictionary (Part 2)
Following the header, the first object in the body of the file (part 2) must be an in-
direct dictionary object, the
linearization parameter dictionary,
containing the pa-
rameters listed in Table F.1. All values in this dictionary must be direct objects.
There are no references to this dictionary anywhere in the document; however,
the first-page cross-reference table (Part 3) contains a normal entry for it.
The linearization parameter dictionary must be entirely contained within the first
1024 bytes of the PDF file. This limits the amount of data a viewer application
must read before deciding whether the file is linearized.
