Change the Transparency of Shape Fill Scheme Color in PowerPoint Presentation in C#

When using a SchemeColor (e.g. Accent2), how to specify the transparency?

shape.FillFormat.SolidFillColor.SchemeColor

@bingxie,
Thank you for posting your question.

To change the transparency of the SchemeColor, you can apply a corresponding color transform operation as shown below:

shape.FillFormat.SolidFillColor.ColorTransform.Add(ColorTransformOperation.SetAlpha, 0.5f);
