string sourceFileName = "SourceFile.psd";
string exportPath = "SourceFileEdited.psd";
string exportPathPng = "SourceFileEdited.png";

using (var image = (PsdImage)Image.Load(sourceFileName))

    var oldBounds = oldLayer.Bounds;

    var oldLayerData = image.Layers[0].LoadArgb32Pixels(oldBounds);

    var layers = new Layer[4];
    for (int i = 0; i < 4; i++)
    {
        layers[i] = new Layer(
            oldBounds,

    layers[1].Crop(new Rectangle(186, 0, 186, 159));
    layers[2].Crop(new Rectangle(0, 159, 186, 142));
    layers[3].Crop(new Rectangle(186, 159, 186, 142));

    oldLayer.Dispose();
    image.Layers = layers;

    var top = 0;
    for (int i = 0; i < 4; i++)

        var width = layers[i].Width;
        var height = layers[i].Height;
        layers[i].Left = 0;

        layers[i].Right = width;
        layers[i].Bottom = height + layers[i].Top;
        top += layers[i].Height;
    }

    // Simpan psd
    image.Save(exportPath, new PsdOptions());

    // Simpan png
    image.Save(exportPathPng, new PngOptions());
