Detailed Description

Text dedicated operator class. This class represents those text operators which contains text to be displayed. This is necessary, because text string stored in operator's operands is not the same as the displayed one in general and may be affected by font encoding.
Use getFontText method to retreive text from text operator filtered through its font code maps.

Member Function Documentation

GfxFont * pdfobjects::TextSimpleOperator::getCurrentFont ( ) const [protected]

Finds current font for operator from fontName. Uses resources from content stream to retriev font by name. Returned instance must not be deallocated by caller.

Returns:: Font instance for this operator.

const char * pdfobjects::TextSimpleOperator::getFontName ( ) const

Returns font name for this operator. May return null if setFontData hasn't been called yet.

Returns:: Font name or NULL if not initialized yet.

References fontData, and pdfobjects::TextSimpleOperator::FontData::getFontName().

void pdfobjects::TextSimpleOperator::getFontText ( std::string & str ) const [virtual]

Returns string represented by this text operator converted according the font encoding.

Parameters:

str

String to be set.

void pdfobjects::TextSimpleOperator::getRawText ( std::string & str ) const [virtual]

Returns string represented by this text operator in raw format. Raw format doesn't take care about font used for this operator.

Parameters:

str

String to be set.

void pdfobjects::TextSimpleOperator::setFontData ( GfxFont * gfxFont )

Sets font specific stuff. This method should be called from StateUpdater when we do know the current font for this operator.
This method doesn't influence operator itself (or its operands).

Parameters:

gfxFont

Xpdf GfxFont instance.

void pdfobjects::TextSimpleOperator::setRawText ( std::string & str )

Sets raw string.
