Does iText honors color transparency?
I'm using iText 5.2.1 and I tried to use the BaseColor constructor with alpha channel, that is

    public BaseColor(final int red, final int green, final int blue, final int alpha)

but when I actually draw text or shapes it seems that the alpha channel isn't taken into account.
For example if I try this

      Font f = ....;
      f.setColor(new BaseColor(130, 130, 130, 50);
      PdfContentByte cb = writer.getDirectContent();
      ColumnText.showTextAligned(cb, Element.ALIGN_LEFT, new Phrase("my text", f),
          refPointX, refPointY, 0);

the text it's written with the color specified but without the alpha information, that is with the color with 100% opacity.
The same thing happens if I try to draw some shape and I specify a fill color with transparency.

In the book *iText in Action second edition* there's nothing about transparency in colors.

Am I wrong?
