Set Alpha of Text

[clifford]

Hi,

I have some Text that I am finding on the slides and I need to set it's Alpha to 0.75 if I can.

This is my current attempt but it's not setting the Alpha just the Color.

    //Update the Colour of the E3 1st Score to the alpha color

    ITextPart E3Text = pptxDoc.Find("XXXXXX", true, true).GetAsOneTextPart();

    E3Text.Font.Color = Syncfusion.Presentation.ColorObject.FromArgb(40, 255, 103, 0);

Thanks

Cliff

    //Gets the first text part from the shape

    ITextPart textPart = shape.TextBody.Paragraphs[0].TextParts[0];

    textPart.Font.Color.SystemColor = Color.FromArgb(255 - 40, 255, 0, 0);

    //Saves the Presentation

    pptxDoc.Save("Output.pptx");

}
