i have to render on QTextDocument XSL-FO file and
all QTextBlockFormat, QTextCharFormat, QTextTableCell QText format class
its does not know to make border color and border size left 3pt bottom 10pt as example..

i found to be useful use the inline svg to thisplay border ....

the tag sample... ( fo:block is like html <P>)

[HTML]
<fo:block>
A text line below the instream object.
</fo:block>
<fo:block>
<fo:instream-foreign-object>
<svg:svg width="250" height="50">
<svg:g style="fill:red; stroke:#000000">
<svg:rect x="0" y="0" width="15" height="15"/>
<svg:rect x="5" y="5" width="15" height="15"/>
</svg:g>
<svg:text x="10" y="30">SVG placed in a block</svg:text>
</svg:svg>
</fo:instream-foreign-object>
</fo:block>
[/HTML]

here is the svg class function that render & take domelement svg transorm and paint..
the problem if i not fill pix.fill(QColor("#ffffff")); the svg is display black ...
now to display varius layer on a scene how i can make this background color transparent?
To to overlap 3 or moore layer ...


Qt Code: 
  1. QPixmap FopFormat::RenderSvg(  const QDomElement e  )
  2. {
  3.     nrloop++;   /* count element to addresource ! */
  4.     /* QString trytosave = QString("svg_%1.svg").arg(nrloop); */
  6.             QDomProcessingInstruction header = em.createProcessingInstruction( "xml", "version=\"1.0\" standalone=\"no\"" );
  7.             em.appendChild( header );
  8.             em.appendChild( e.firstChildElement() );
  9.     QDomElement root = em.documentElement();
  10.     root.setAttribute ("xmlns","http://www.w3.org/2000/svg");
  11.     root.setAttribute ("version","1.2");
  12.     root.setAttribute ("baseProfile","tiny");
  13.     QString srcsv = em.toString();
  14.     if (srcsv.contains("svg:svg")) {
  15.     srcsv = srcsv.replace("svg:","");
  16.     }
  17.     /*  try to save to show on firefox if work 
  18.         QFile f( trytosave );
  19.         if ( f.open( QFile::WriteOnly | QFile::Text ) )
  20.         {
  21.         QTextStream sw( &f );
  22.         sw << srcsv;
  23.         f.close();
  24.         }
  25.     */
  26.     QByteArray    streamsvg;
  27.     streamsvg.append ( srcsv ); 
  28.     QSvgRenderer  svgRenderer( streamsvg );
  29.     QPixmap pix(  svgRenderer.defaultSize() );
  30.         pix.fill(QColor("#ffffff"));
  31.     QPainter paint(&pix);
  32.         svgRenderer.render(&paint);
  33.     if (pix.isNull() ) {
  34.     QPixmap pixe(22,22);

  39.     }
  40. }
  41.  
  42.  
  43. bool FopFormat::ObjectParserTag(  const QDomElement &e  )
  44. {
  45.     nrloop++;
  46.     QDomElement domObject = e.firstChildElement();
  47.     if ( domObject.tagName().toLower() == "svg:svg" || domObject.tagName().toLower() == "svg" ) {
  48.         QPixmap paintsvg = RenderSvg(e);
  49.         Tdoc->addResource( QTextDocument::ImageResource, QUrl(QString("%1").arg(nrloop)), paintsvg );
  51.         format.setName( QString("%1").arg(nrloop) );
  52.         format.setToolTip(QString("SVG dom."));
  53.         Tcursor.insertImage( format );  /* cursor insert image QPixmap */
