SectionDividerLayer.GetRelatedLayerGroup method

Gets the LayerGroup that’s related to this SectionDividerLayer instance.

public LayerGroup GetRelatedLayerGroup()

Return Value

The LayerGroup instance.

Examples

The following code demonstrates SectionDividerLayer layers and how to get the related to it LayerGroup.

[C#]

// The following code demonstrates SectionDividerLayer layers and how to get the related to it LayerGroup.

// Layers hierarchy
//    [0]: '</Layer group>' SectionDividerLayer for Group 1
//    [1]: 'Layer 1' Regular Layer
//    [2]: '</Layer group>' SectionDividerLayer for Group 2
//    [3]: '</Layer group>' SectionDividerLayer for Group 3
//    [4]: 'Group 3' GroupLayer
//    [5]: 'Group 2' GroupLayer
//    [6]: 'Group 1' GroupLayer

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

using (var image = new PsdImage(100, 100))
{
    // Creating layers hierarchy
    // Add the LayerGroup 'Group 1'
    LayerGroup group1 = image.AddLayerGroup("Group 1", 0, true);
    // Add regular layer
    Layer layer1 = new Layer();
    layer1.DisplayName = "Layer 1";
    group1.AddLayer(layer1);
    // Add the LayerGroup 'Group 2'
    LayerGroup group2 = group1.AddLayerGroup("Group 2", 1);
    // Add the LayerGroup 'Group 3'
    LayerGroup group3 = group2.AddLayerGroup("Group 3", 0);

    // Gets the SectionDividerLayer's
    SectionDividerLayer divider1 = (SectionDividerLayer)image.Layers[0];
    SectionDividerLayer divider2 = (SectionDividerLayer)image.Layers[2];
    SectionDividerLayer divider3 = (SectionDividerLayer)image.Layers[3];

    // using the SectionDividerLayer.GetRelatedLayerGroup() method, obtains the related LayerGroup instance.
    AssertAreEqual(group1.DisplayName, divider1.GetRelatedLayerGroup().DisplayName); // the same LayerGroup
    AssertAreEqual(group2.DisplayName, divider2.GetRelatedLayerGroup().DisplayName); // the same LayerGroup
    AssertAreEqual(group3.DisplayName, divider3.GetRelatedLayerGroup().DisplayName); // the same LayerGroup

    LayerGroup folder1 = divider1.GetRelatedLayerGroup();
    AssertAreEqual(5, folder1.Layers.Length); // 'Group 1' contains 5 layers
