vsdump - VSD/VSS file format reverse engineering

SYNOPSIS


vsdump [SUBOPTIONS] FILE

DESCRIPTION


This manual page documents briefly the vsdump command.

vsdump is an ALT Linux (www.altlinux.ru) project of VSD/VSS file format reverse
engineering. VSD/VSS is an OLE file. Main data is stored in 'VisioDocument' file inside
this OLE. 'VisioDocument' file has a header with version number and pointer to the 1st
stream. Pointers contain Type, Offset to the start, Length, and Format of stream. The
Format field has a 'compressed' flag (the 2nd least significant bit).

Format == 0x4* is used for streams that contains some strings.
Format == 0x5* is used for streams that contains some pointers.
Format == 0xd* is used for streams made of chunks.

Type == 15 is used for streams that contains 'Page' data.
Type == 23 is used for streams that contains Icons.
And so on.

To (de)compress some streams Visio uses some version of LZW algorithmwith options
different from other MS-Office applications.

Those streams are made of chunks. Chunks starts with header that contains Type and Length
fields. Most of chunk types has a mandatory fields and some of them has a discretionary
fields. The type of chunk imply an order and format of mandatory fields and place of start
for discretionary fields (if any).

The discrepionary fields made of 'blocks'. Blocks start with length, type fields and index
of variable it is linked to.
Blocks made of 'slices'. Every slice can be single byte operation like "+" or "*" or
'command' to put one/two bytes data or IEEE-754 fraction or stringor name or function into
formula.
