Methods

NameDescription
GetEffectBounds(Rectangle, int)Calculate and gets the bounds of effect pixels based on input layer pixels bounds.

Examples

The following code demonstrates support for the PsdImage.GlobalAngle property to change the global angle value.

[C#]

// When DropShadowEffect.UseGlobalLight property is 'true', then DropShadowEffect object use angle value from PsdImage.GlobalAngle property.

using (PsdImage image = (PsdImage)Image.Load("4.psd"))
{
    image.GlobalAngle = 30;
    image.Save("output.psd");
}

The following code demonstrates using the Opacity property of DropShadowEffect.

[C#]

string inputFile = "input.psd";
string outputImage20 = "outputImage20.png";
string outputImage200 = "outputImage200.png";

using (PsdImage psdImage = (PsdImage)Image.Load(inputFile, new LoadOptions()))
{
    Layer workLayer = psdImage.Layers[1];

    DropShadowEffect dropShadowEffect = workLayer.BlendingOptions.AddDropShadow();
    dropShadowEffect.Distance = 0;
    dropShadowEffect.Size = 8;

    // Example with Opacity = 20
    dropShadowEffect.Opacity = 20;
    psdImage.Save(outputImage20, new PngOptions());

    // Example with Opacity = 200
    dropShadowEffect.Opacity = 200;
    psdImage.Save(outputImage200, new PngOptions());
}
