FloatingBox cannot deal with transparency

Hi,

even if I add a Alpha-Value to the Color (use ARGB) the floatingbox is not trasparent or semi transparent.
Please check this.

Best regards.

This is my CodeSnippet:

public static void FloatingBoxWithSemiTransparentBackground()
{
var pdf = new Document(“C:\DEV\Test.pdf”);
var page = pdf.Pages[1];

        var fullYellow = System.Drawing.Color.FromArgb(255, System.Drawing.Color.Yellow);
        var asposeVersionOfFullYellow = Aspose.Pdf.Color.FromRgb(fullYellow);
        var floatingBoxFullYellow = new FloatingBox(100, 200) { Left = 30, Top = 40, BackgroundColor = asposeVersionOfFullYellow };
        page.Paragraphs.Add(floatingBoxFullYellow);

        var semiTransparentYellow = System.Drawing.Color.FromArgb(10, System.Drawing.Color.Yellow);
        var asposeVersionOfSemiYellow = Aspose.Pdf.Color.FromRgb(semiTransparentYellow);
        var floatingBoxSemiYellow = new FloatingBox(100, 200) { Left = 150, Top = 40, BackgroundColor = asposeVersionOfSemiYellow };
        page.Paragraphs.Add(floatingBoxSemiYellow);

        pdf.Save("C:\\DEV\\Test_Apha.pdf");
    }

Find attached the file and the result as PDF.
