From source file:org.pentaho.reporting.engine.classic.core.layout.process.text.ComplexTextMinorAxisLayoutStep.java

private void addCompleteLine(final ParagraphRenderBox box, final ParagraphPoolBox lineBoxContainer,
        final StyleSheet layoutContext) {

            fontRenderContext);//w  ww.j  a v  a  2  s. c  o  m
    double height = textLayout.getAscent() + textLayout.getDescent() + textLayout.getLeading();

    final RenderableComplexText text = richText.create(lineBoxContainer);
    text.setTextLayout(textLayout);
    ParagraphFontMetricsImpl metrics = new ParagraphFontMetricsImpl();
    metrics.update(textLayout);
    final RenderBox line = generateLine(box, lineBoxContainer, text, height, metrics);
    // and finally add the line to the paragraph
    getNodeContext().updateX2(line.getCachedX2());
    box.addGeneratedChild(line);
