SmartObjectResourceCompId Property
Gets or sets the ID of the currently selected comp for the child document, which will be -1 if none are selected. Comps are compositions of a page layout which designers can create. Using layer comps, you can create, manage, and view multiple versions of a layout in a single Adobe® Photoshop® file. A layer comp is a snapshot of a state of the Layers panel. Layer comps save three types of layer options but this property gets the Layer Comp selection identifier for he smart object layer in the PSD file. Layer comps in Smart Objects

Namespace: Aspose.PSD.FileFormats.Psd.Layers.LayerResources
Assembly: Aspose.PSD (in Aspose.PSD.dll) Version: 21.10
Syntax
public int CompId { get; set; }

Property Value

Type: Int32
The ID of the currently selected comp for the child document in the PSD image, which will be -1 if none are selected.
