Detailed Description

the main class to read/store picture in a Pc MS Works document v1-4

This class must be associated with a WPS4Parser.

Note
As the pictures seems always be given with character' position, many functions which exists to maintain the same structures that exist(will) in WPS8TextGraph class do almost nothing.

Constructor & Destructor Documentation

WPS4Graph::WPS4Graph ( WPS4Parser parser)
explicit

constructor given the main parser of the MN0 zone

WPS4Graph::~WPS4Graph ( )

destructor

WPS4Graph::WPS4Graph ( WPS4Graph const &  orig)
private

Member Function Documentation

libwps::DebugFile& WPS4Graph::ascii ( )
inlineprotected

returns the debug file

Referenced by readObject().

void WPS4Graph::computePositions ( ) const

computes the position of all found figures.

In reality, as all the pictures seemed to be given with characters positions, it does almost nothing, ie it only updates some internal bool to know the picture which have been sent to the listener.

int WPS4Graph::numPages ( ) const

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

WPS4Graph& WPS4Graph::operator= ( WPS4Graph const &  orig)
private
int WPS4Graph::readObject ( RVNGInputStreamPtr  input,
WPSEntry const &  entry 
)
protected

tries to find a picture in the zone pointed by entry

Returns
the object id or -1 if find nothing
Note
the content of this zone is mainly unknown, so this function may failed to retrieved valid data
void WPS4Graph::sendObject ( WPSPosition const &  position,
int  id 
)
protected

sends an object with identificator id as a character to a given pposition

void WPS4Graph::sendObjects ( int  page)
protected

send all the objects of a given page:

Parameters
pageif page < 0, sends all the pictures which have not been used,

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

void WPS4Graph::setListener ( WPSContentListenerPtr listen)
inline

sets the listener

void WPS4Graph::storeObjects ( std::vector< WPSOLEParserObject > const &  objects,
std::vector< int > const &  ids 
)
protected

store a list of object

int WPS4Graph::version ( ) const
protected

returns the file version
