Usage Examples

Read Gradient Stops 

using Aspose.Slides.Foss;

using var prs = new Presentation("deck.pptx");
var shape = prs.Slides[0].Shapes[0];
if (shape.FillFormat.FillType == FillType.Gradient)
{
    var grad = shape.FillFormat.GradientFormat;
    Console.WriteLine($"Direction: {grad.GradientDirection}");
    foreach (var stop in grad.GradientStops)
    {
        Console.WriteLine($"  Position {stop.Position}: {stop.Color.Color}");
    }
}

Read Pattern Fill 

using Aspose.Slides.Foss;

using var prs = new Presentation("deck.pptx");
var shape = prs.Slides[0].Shapes[0];
if (shape.FillFormat.FillType == FillType.Pattern)
{
    var pat = shape.FillFormat.PatternFormat;
    Console.WriteLine($"Style: {pat.PatternStyle}");
    Console.WriteLine($"Foreground: {pat.ForeColor.Color}");
    Console.WriteLine($"Background: {pat.BackColor.Color}");
}
