Methods' Summary
queryTextShapes	Extract the polygonal shapes of the given text. Each glyph is represented by a separate polyPolygon in the returned sequence.
queryTightMeasures	Query the tight bounding boxes for every character in the given text string. Tight bounding boxes means that for e.g. an 'a', the bounding box for the polyPolygon describing the glyph 'a' is returned, not the logical dimensions of the character in the font.
queryTextMeasures	Query the logical bounding boxes of every character in the given text string. Logical bounding boxes means the space that the font allocates for the given character, which, e.g. for a '.', might be significantly broader than the bounds returned via queryTightMeasures.
queryTextOffsets	Query the offsets of the output corresponding to every character in the given text string. The result of this method can be directly fed into the XCanvas::drawOffsettedText method.
queryTextBounds	Similar to queryTextMeasures, only that the overall bounds are returned by this method.
getFontDescriptor	Query the FontDescriptor that was used to generate this object.
getFontMetrics
getAssociatedCanvas	Query the Canvas this font was generated from.

Methods' Details

queryTextShapes sequence< XPolyPolygon2D > queryTextShapes(   [in] StringContext [in] ViewState [in] RenderState [in] TextDirection   text, viewState, renderState, direction ); Description Extract the polygonal shapes of the given text. Each glyph is represented by a separate polyPolygon in the returned sequence.

queryTightMeasures sequence< Rectangle2D > queryTightMeasures(   [in] StringContext [in] ViewState [in] RenderState [in] TextDirection   text, viewState, renderState, direction ); Description Query the tight bounding boxes for every character in the given text string. Tight bounding boxes means that for e.g. an 'a', the bounding box for the polyPolygon describing the glyph 'a' is returned, not the logical dimensions of the character in the font.

queryTextMeasures sequence< Rectangle2D > queryTextMeasures(   [in] StringContext [in] ViewState [in] RenderState [in] TextDirection   text, viewState, renderState, direction ); Description Query the logical bounding boxes of every character in the given text string. Logical bounding boxes means the space that the font allocates for the given character, which, e.g. for a '.', might be significantly broader than the bounds returned via queryTightMeasures.

queryTextOffsets sequence< double > queryTextOffsets(   [in] StringContext [in] ViewState [in] RenderState [in] TextDirection   text, viewState, renderState, direction ); Description Query the offsets of the output corresponding to every character in the given text string. The result of this method can be directly fed into the XCanvas::drawOffsettedText method.

queryTextBounds Rectangle2D queryTextBounds(   [in] StringContext [in] ViewState [in] RenderState [in] TextDirection   text, viewState, renderState, direction ); Description Similar to queryTextMeasures, only that the overall bounds are returned by this method.

getFontDescriptor FontDescriptor getFontDescriptor();     Description Query the FontDescriptor that was used to generate this object.

getFontMetrics FontMetrics getFontMetrics();

getAssociatedCanvas XCanvas getAssociatedCanvas();     Description Query the Canvas this font was generated from.
