## 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() [1/2]

WPS4Graph::WPS4Graph | ( | WPS4Parser & | parser | ) |
| explicit

constructor given the main parser of the MN0 zone

Referenced by operator=(), and WPS4Graph().

## ◆ ~WPS4Graph()

WPS4Graph::~WPS4Graph | ( |  | ) |

destructor

## ◆ WPS4Graph() [2/2]

WPS4Graph::WPS4Graph | ( | WPS4Graph const & | orig | ) |
| private delete

## Member Function Documentation

## ◆ ascii()

libwps::DebugFile & WPS4Graph::ascii | ( |  | ) |
| inline protected

returns the debug file

Referenced by readObject(), and WPS4Graph().

## ◆ computePositions()

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.

## ◆ numPages()

int WPS4Graph::numPages | ( |  | ) | const

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

## ◆ operator=()

WPS4Graph & WPS4Graph::operator= | ( | WPS4Graph const & | orig | ) |
| private delete

## ◆ readObject()

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

## ◆ sendObject()

void WPS4Graph::sendObject | ( | WPSPosition const & | position,
|  | int | id )
| protected

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

## ◆ sendObjects()

void WPS4Graph::sendObjects | ( | int | page | ) |
| protected

send all the objects of a given page:

Parameters

  page | if 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.

## ◆ setListener()

void WPS4Graph::setListener | ( | WPSContentListenerPtr & | listen | ) |
| inline

sets the listener

## ◆ storeObjects()

void WPS4Graph::storeObjects | ( | std::map< int, WPSEmbeddedObject > const & | objectsMap | ) |
| protected

store a list of object

## ◆ version()

int WPS4Graph::version | ( |  | ) | const
| protected

returns the file version
