Examples

The following code demonstrates classes hierarchy of layer section resources.

[C#]

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

string srcFile = "123 1.psd";
string outFile = "output.psd";

using (var psdImage = (PsdImage)Image.Load(srcFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
    AssertAreEqual((psdImage.Layers[3].Resources[3] as LayerSectionResource).SectionType, LayerSectionType.SectionDivider);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as LsdkResource).SectionType, LayerSectionType.SectionDivider);

    AssertAreEqual((psdImage.Layers[3].Resources[3] as BaseLayerSectionResource).SectionType, LayerSectionType.SectionDivider);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).SectionType, LayerSectionType.SectionDivider);

    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).Length, 4);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).BlendModeKey, BlendMode.Absent);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).Subtype, LayerSectionSubtype.NotUsed);

    psdImage.Save(outFile);
}

// check after saving
using (var psdImage = (PsdImage)Image.Load(outFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
    AssertAreEqual((psdImage.Layers[3].Resources[3] as LayerSectionResource).SectionType, LayerSectionType.SectionDivider);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as LsdkResource).SectionType, LayerSectionType.SectionDivider);

    AssertAreEqual((psdImage.Layers[3].Resources[3] as BaseLayerSectionResource).SectionType, LayerSectionType.SectionDivider);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).SectionType, LayerSectionType.SectionDivider);

    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).Length, 4);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).BlendModeKey, BlendMode.Absent);
    AssertAreEqual((psdImage.Layers[8].Resources[3] as BaseLayerSectionResource).Subtype, LayerSectionSubtype.NotUsed);
}

File.Delete(outFile);
