Member Function Documentation

void WPS4Parser::appendCP1252 (  const uint8_t  readVal,
WPS4Listener *  listener
)  [private]
 

Take a character in CP1252 encoding, convert it and append it to the text buffer as UTF8.

void WPS4Parser::appendCP850 (  const uint8_t  readVal,
WPS4Listener *  listener
)  [private]
 

Take a character in CP850 encoding, convert it and append it to the text buffer as UTF8.

void WPS4Parser::parse (  WPSInputStream *  stream,
WPS4Listener *  listener
)  [private]
 

void WPS4Parser::parse (  WPXHLListenerImpl *  listenerImpl  )  [virtual]
 

Implements WPSParser.

void WPS4Parser::parsePages (  std::list< WPSPageSpan > &  pageList,
WPSInputStream *  input
)  [private]
 

Read the page format from the file.

It seems that WPS4 files can only have one page format throughout the whole document.

void WPS4Parser::propertyChange (  std::string  rgchProp,
WPS4Listener *  listener
)  [private]
 

Process a character property change.

The Works format supplies all the character formatting each time there is any change (as opposed to HTML, for example). In Works 4, the position in in rgchProp is significant (e.g., bold is always in the first byte).

void WPS4Parser::propertyChangeDelta (  uint32_t  newTextAttributeBits,
WPS4Listener *  listener
)  [private]
 

Parameters:
newTextAttributeBits,: all the new, current bits (will be compared against old, and old will be discarded).

void WPS4Parser::propertyChangeTextAttribute (  const uint32_t  newTextAttributeBits,
const uint8_t  attribute,
const uint32_t  bit,
WPS4Listener *  listener
)  [private]
 

bool WPS4Parser::readFODPage (  WPSInputStream *  input,
std::vector< FOD > *  FODs
)  [private]
 

Read a single "page" (128 bytes) that contains formatting descriptors (FODs) for either characters OR paragraphs.

Starts reading at current position in stream.

Return: true if more pages of this type exist, otherwise false

void WPS4Parser::readFontsTable (  WPSInputStream *  input  )  [private]
 

Reads fonts table into memory.

void WPS4Parser::readText (  WPSInputStream *  input,
WPS4Listener *  listener
)  [private]
 

Read the text of the document using previously-read formatting information.
