Detailed Description

the main class to read/store pictures in a Pc MS Works document v5-8

This class must be associated with a WPS8Parser. It contains code to read the BDR/WBDR, PICT/MEF4, IBGF entries and to store the pictures which are found in the other ole parts.

Note

As the pictures seems always be given with characters positions, many functions which exists to maintain the same structures that exist in the other WPS*MNGraph classes do almost nothing.

Member Function Documentation

ascii()

libwps::DebugFile & WPS8Graph::ascii ( )

inlineprotected

returns the debug file

Referenced by readBDR(), readIBGF(), readPICT(), and WPS8Graph().

computePositions()

void WPS8Graph::computePositions

(

)

const

computes the final position of all found figures.

In reality, as all the pictures seemed to be given with characters positions, it does nothing

numPages()

int WPS8Graph::numPages

(

)

const

returns the number page where we find a picture. In practice, 0/1

operator=()

WPS8Graph & WPS8Graph::operator= ( WPS8Graph const & orig )

privatedelete

readBDR()

bool WPS8Graph::readBDR ( RVNGInputStreamPtr const & input, WPSEntry const & entry )

protected

parsed BDR/WBDR zone: a complex border formed with 8 pictures

Referenced by readStructures().

readIBGF()

bool WPS8Graph::readIBGF ( RVNGInputStreamPtr const & input, WPSEntry const & entry )

protected

reads a IBGF zone: an entry to a background picture

This small entry seems to contain only an identificator which pointed to a PICT Zone

Referenced by readStructures().

readPICT()

bool WPS8Graph::readPICT ( RVNGInputStreamPtr const & input, WPSEntry const & entry )

protected

reads a PICT/MEF4 entry : reads uncompressed picture of sx*sy of rgb

This kind of entry seems mainly used to store a background picture

Referenced by readStructures().

readStructures()

bool WPS8Graph::readStructures ( RVNGInputStreamPtr const & input )

protected

finds all entries which correspond to some pictures, parses them and stores data

sendBorder()

void WPS8Graph::sendBorder ( int borderId )

protected

sends the border frames.

Actually, sends the eight consecutive pictures which form a border on 3 consecutive lines

Referenced by sendObjects().

sendIBGF()

bool WPS8Graph::sendIBGF	(	WPSPosition const &	pos,
		int	ibgfId )

sends data corresponding to a ibgf entry on a given pos position

sendObject()

bool WPS8Graph::sendObject	(	WPSPosition const &	pos,
		int	id,
		bool	ole )

sends an object

Parameters

pos	the object position in the document
id	the object identificator
ole	indicated if we look for objects coming from a ole zone or objects coming from a Pict zone

Referenced by sendIBGF().

sendObjects()

void WPS8Graph::sendObjects	(	int	page,
		int	pageToIgnore = -2 )

send all the objects of a given page:

Parameters

page	if page < 0, sends all the pictures which have not been used,
pageToIgnore	pictures on this pages are not send

As all the pictures seemed to be given with characters positions, this function only does something if page < 0.

setListener()

void WPS8Graph::setListener ( WPSContentListenerPtr & listen )

inline

sets the listener

storeObjects()

void WPS8Graph::storeObjects ( std::map< int, WPSEmbeddedObject > const & objectsMap )

protected

adds a list of object

version()

int WPS8Graph::version ( ) const

protected

returns the file version
