Contoh

Kode berikut menunjukkan cara membuat filter cerdas kustom yang memiliki perender kustom.

[C#]

public void CustomSmartFilterExample(string sourceFile = "psdnet1057.psd", string outputPsd = "out_psdnet1057.psd", string outputPng = "out_psdnet1057.png")

        smartFilter.ApplyToMask(maskLayer);

        // Terapkan filter ke lapisan
        smartFilter.Apply(regularLayer);

        image.Save(outputPsd);
        image.Save(outputPng, new PngOptions());
    }
}

        // dapatkan nilai Ukuran Kristalisasi
        var valueStructure = (IntegerStructure) filterDescriptor.Structures[0];

        for (int i = 0; i < pixelsData.Pixels.Length; i++)
        {
