| offset (base 10) | field | type | size | bitfield | comments | 0 | | rgfc | FC[fkp.crun+1] | | Each FC is the limit FC of a paragraph (i.e. points to the next character past an end of paragraph mark). There will be fkp.crun+1 recorded in the FKP. | 4*(fkp.crun+1) | rgbx | BX[fkp.crun] | | an array of the BX data structure. The ith BX entry in the array describes the paragraph beginning at fkp.rgfc[i]. The BX is a 13 byte data structure. The first byte of each BX is the word offset of the PAPX recorded for the paragraph corresponding to this BX. .. If the byte stored is 0, this represents a 1 line paragraph 15 pixels high with Normal style (stc == 0) whose column width is 7980 dxas | The last 12 bytes of the BX is a PHE structure which stores the current paragraph height for the paragraph corresponding to the BX. If a plcfphe has an entry that maps to the FC for this paragraph, that entry's PHE overrides the PHE stored in the FKP.11*fkp.crun+4 unused space As new runs/paragraphs are recorded in the FKP, unused space is reduced by 17 if CHPX/PAPX is already recorded and is reduced by 17+sizeof(PAPX) if property is not already recorded. 511-sizeof(grppapx) | grppapx | | array of bytes | grppapx consists of all of the PAPXs stored in FKP concatenated end to end. Each PAPX begins with a count of words which records its length padded to a word boundary. | 511 | crun | byte | | count of paragraphs for PAPX FKP. | |
