How i find the best way to convert AlphaColor Background qcolor to html value
HTML only having from 0.00 transparent to 1.00
and AlphaColor 1-255

and on html visible is from 0.7 to 1.0 !!
Have you a valid hack?



Qt Code: 
  1. /* QGraphicsTextItem document()  to div layer QFileInfo f destination file html 
  2. to save external image if exist..
  3. */
  4. QString FloatDiagram::toDivHtml( QFileInfo f )
  5. {
  6.     ///// #define POINT_TO_MM(mm) ((mm)/2.83465058)  point px mm ?? ////
  7.     #define ALPHAHTML(alpha) ((alpha)/254.99999999)
  8.     QString masterpath = f.absolutePath()+"/"+FOPIMAGEDIR;
  9.     /* Paint QGraphicsTextItem style to html css inline */
  10.     QString styles = "position:absolute; top:"+QString("%1px")
  11.     .arg(pos().y())+"; left:"+QString("%1px")
  12.     .arg(pos().x())+"; width:"+QString("%1px")
  13.     .arg(wi)+"; height:"+QString("%1px")
  14.     .arg(hi)+"; ";
  15.  
  16.     if (AlphaColor < 44) {
  17.     styles.append(QString("background-color:transparent; ") );
  18.     } else {
  19.     styles.append(QString("background-color:%1; ").arg( BGColor.name() ) );  
  20.     }
  21.     /* AlphaColor = backgroundqcolor.alpha(); */
  22.     int alFaCol = qBound(0,AlphaColor,256);
  23.     qreal percentos = ALPHAHTML( alFaCol );
  24.     if (percentos < 1 && AlphaColor > 44) {
  25.     QString Tnetto = QString("%1").arg(percentos, 0, 'f', 4);
  26.     styles.append(QString("opacity:%1; filter: alpha(opacity=%1); -moz-opacity:%1; ").arg( Tnetto) );
  27.     }
  28.     /* insert border having? */
  29.     if (BorderDicks > 0 ) {
  30.     styles.append(QString("border:%2px solid %1; ").arg(MarginColor.name()).arg(BorderDicks));
  31.     }
  32.     /* IE !zindex qreal play as int zValue() */
  33.     styles.append(QString("z-index:%1;").arg(QString("%1").arg(zValue()).replace(".","")));

  38.                 blox.setAttribute ("style",styles);
  39.     doc.appendChild(blox);

  41.     QString errorStr;

  44.     if (!exdoc.setContent(document()->toHtml(),false, &errorStr, &errorLine, &errorColumn)) {
