Class LnkeResource

LnkeResource class

Defines the LnkeResource class that contains information about external linked files or assets in the PSD format image. The link resource may contain several LiFeDataSource instances which can be accessed by indexer. This is a part of PSD File Format Manipulation API that helps to modify Adobe® Photoshop® files programmatically

public class LnkeResource : LinkResource

Constructors

Name	Description
LnkeResource()	Initializes a new instance of the `LnkeResource` class.
LnkeResource(LinkDataSource[])	Initializes a new instance of the `LnkeResource` class.

Properties

Name	Description
DataSourceCount { get; }	Gets the count of link data sources which can be accessed by the indexer.
IsEmpty { get; }	Gets a value indicating whether this link resource instance is empty.
Item { get; }	Gets the `LiFeDataSource` at the specified index. (2 indexers)
Key { get; }	Gets the layer resource key.
override Length { get; }	Gets the PSD global link resource length in bytes.
PsdVersion { get; }	Gets the minimal psd version required for layer resource. 0 indicates no restrictions.
virtual Signature { get; }	Gets the signature.

Methods

Name	Description
override Save(StreamContainer, int)	Saves the resource block data.
override ToString()	Returns a String that represents this instance.

Fields

Name	Description
const TypeToolKey	The type tool info key.

Examples

The following code demonstrates the support of the LnkeResource resource.

[C#]

void AssertIsTrue(bool condition)
{
    if (!condition)
    {
        throw new FormatException(string.Format("Expected true"));
    }
}

void AssertAreEqual(object actual, object expected)
{
    if (!object.Equals(actual, expected))
    {
        throw new FormatException(string.Format("Actual value {0} are not equal to expected {1}.", actual, expected));
    }
