* grpprls of the paragraph and character properties of the document. A grpprl
|
||||
* is a list of sprms(decompression operations) to perform on a parent style.
|
||||
*
|
||||
* The style properties for paragraph and character runs
|
||||
* are stored in fkps. There are PAP fkps for paragraph properties and CHP fkps
|
||||
* for character run properties. The first part of the fkp for both CHP and PAP
|
||||
* fkps consists of an array of 4 byte int offsets in the main stream for that
|
||||
* Paragraph's or Character run's text. The ending offset is the next
|
||||
* value in the array. For example, if an fkp has X number of Paragraph's
|
||||
* stored in it then there are (x + 1) 4 byte ints in the beginning array. The
|
||||
* number X is determined by the last byte in a 512 byte fkp.
|
||||
*
|
||||
* CHP and PAP fkps also store the compressed styles(grpprl) that correspond to
|
||||
* the offsets on the front of the fkp. The offset of the grpprls is determined
|
||||
* differently for CHP fkps and PAP fkps.
