It contains all needed information. If it is not handled by a renderer, its decomposition will provide the text tools::PolyPolygon outlines as filled polygons, correctly transformed. To get better text quality, it is suggested to handle tis primitive directly in a renderer. In that case, e.g. hintings on the system can be supported. @param maTextTransform The text transformation contains the text start position (always baselined) as translation, the FontSize as scale (where width relative to height defines font scaling and width == height means no font scaling) and the font rotation and shear. When shear is used and a renderer does not support it, it may be better to use the decomposition which will do everything correctly. Same is true for mirroring which would be expressed as negative scalings. @param rText The text to be used. Only a part may be used, but a bigger part of the string may be necessary for correct layouting (e.g. international) @param aTextPosition The index to the first character to use from rText @param aTextLength The number of characters to use from rText @param rDXArray The distances between the characters. This parameter may be empty, in that case the renderer is responsible to do something useful. If it is given, it has to be of the size aTextLength. Its values are in logical coordinates and describe the distance for each character to use. This is independent from the font width which is given with maTextTransform. The first value is the offset to use from the start point in FontCoordinateSystem X-Direction (given by maTextTransform) to the start point of the second character @param rFontAttribute The font definition @param rLocale The locale to use @param rFontColor The font color to use @param bFilled @param nWidthToFill @param rFillColor Text background color (has nothing to do with bFilled and nWidthToFill) */ class DRAWINGLAYER_DLLPUBLIC TextSimplePortionPrimitive2D : public BufferedDecompositionPrimitive2D { private: /// text transformation (FontCoordinateSystem) basegfx::B2DHomMatrix maTextTransform; /// The text, used from maTextPosition up to maTextPosition + maTextLength OUString maText; /// The index from where on maText is used sal_Int32 mnTextPosition; /// The length for maText usage, starting from maTextPosition sal_Int32 mnTextLength; /// The DX array in logic units ::std::vector< double > maDXArray; /// The font definition attribute::FontAttribute maFontAttribute; /// The Locale for the text ::com::sun::star::lang::Locale maLocale; /// font color basegfx::BColor maFontColor; /// #i96669# internal: add simple range buffering for this primitive basegfx::B2DRange maB2DRange; bool mbFilled; // Whether to fill a given width with the text long mnWidthToFill; // the width to fill /// The fill color of the text Color maTextFillColor; protected: /// local decomposition. virtual Primitive2DSequence create2DDecomposition(const geometry::ViewInformation2D& rViewInformation) const SAL_OVERRIDE; public: /// constructor TextSimplePortionPrimitive2D( const basegfx::B2DHomMatrix& rNewTransform, const OUString& rText, sal_Int32 nTextPosition, sal_Int32 nTextLength, const ::std::vector< double >& rDXArray, const attribute::FontAttribute& rFontAttribute, const ::com::sun::star::lang::Locale& rLocale, const basegfx::BColor& rFontColor, bool bFilled = false, long nWidthToFill = 0, const Color& rFillColor = COL_TRANSPARENT ); /// helpers /** get text outlines as polygons and their according ObjectTransformation.
