GrdmResource.Reverse

GrdmResource.Reverse property

Is gradient reversed.

public bool Reverse { get; set; }

Examples

The following code demonstrates support of GrdmResource resource.

[C#]

string sourceFile = "gradient_map_default.psd";
string outputFile = "gradient_map_res.psd";

using (var image = (PsdImage)Image.Load(sourceFile, new PsdLoadOptions()))
{
    Layer layer = image.Layers[1];
    GrdmResource grdmResource = (GrdmResource)layer.Resources[0];
            
    // check current values
    AssertAreEqual(false, grdmResource.Reverse);
    AssertAreEqual((ulong)65535, grdmResource.ColorPoints[1].RawColor.Components[2].Value);
    AssertAreEqual((ulong)65535, grdmResource.ColorPoints[1].RawColor.Components[3].Value);
            
            
    grdmResource.Reverse = true;
    // Red color for second gradient color point
    grdmResource.ColorPoints[1].RawColor.Components[1].Value = ushort.MaxValue;
    grdmResource.ColorPoints[1].RawColor.Components[2].Value = 0;
    grdmResource.ColorPoints[1].RawColor.Components[3].Value = 0;

    image.Save(outputFile, new PsdOptions());
}

using (var image = (PsdImage)Image.Load(outputFile))
{
    Layer layer = image.Layers[1];
    GrdmResource grdmResource = (GrdmResource)layer.Resources[0];
    
    // check changed values
    AssertAreEqual(true, grdmResource.Reverse);
    AssertAreEqual((ulong)0, grdmResource.ColorPoints[1].RawColor.Components[2].Value);
    AssertAreEqual((ulong)0, grdmResource.ColorPoints[1].RawColor.Components[3].Value);
}

void AssertAreEqual(object expected, object actual, string message = null)
{
    if (!object.Equals(expected, actual))
    {
        throw new Exception(message ?? "Objects are not equal.");
    }
}
