Class SmartResourceCreator

SmartResourceCreator class

Defines the SmartResourceCreator class that can create PlLd, SoLd and SoLe resources. Is is used to support smart object layers in the Adobe® Photoshop® images.

public class SmartResourceCreator

Constructors

NameDescription
SmartResourceCreator()Initializes a new instance of the SmartResourceCreator class.
SmartResourceCreator(PlacedResource)Initializes a new instance of the SmartResourceCreator class with the given template.
SmartResourceCreator(bool, bool)Initializes a new instance of the SmartResourceCreator class.

Methods

NameDescription
GeneratePlacedResource()Generates the placed resource.
GenerateSmartEmbeddedResource()Generates the embedded smart object resource.
GenerateSmartExternalResource()Generates the external smart object resource.

Examples

The following code demonstrates the support of the SoLEResource, SmartObjectResource and PlacedResource resources.
