Hi,

There is alpha value in System.Drawing.Color which could set the transparencey. Please refer to following code:

Code: Select all

label1.TextFrame.TextRange.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Solid;
//set the transparency of the of datalabel
label1.TextFrame.Paragraphs[0].DefaultCharacterProperties.Fill.SolidColor.Color = Color.FromArgb(60, Color.Red);

If this doesn't meet your requirement, please provide more information such as your input file and the expected output file.
