Syntax

public static class XRReferenceImageLibraryExtensions

Remarks

At runtime, XRReferenceImageLibrarys are immutable. These Editor-only extension methods let you build and manipulate image libraries in Editor scripts.

Methods

Add(XRReferenceImageLibrary)

Creates an empty XRReferenceImage and adds it to the library. The new reference image is inserted at the end of the list of reference images.

Declaration

public static void Add(this XRReferenceImageLibrary library)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.

Exceptions

Type	Condition
ArgumentNullException	Thrown if library is null.

ClearDataStore(XRReferenceImageLibrary)

Clears the binary data store.

Declaration

public static void ClearDataStore(this XRReferenceImageLibrary library)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.

Remarks

Provider-specific binary data can be associated with each XRReferenceImageLibrary (see SetDataForKey(XRReferenceImageLibrary, String, Byte[])). This is used to store arbitrarily large blocks of binary data required at runtime -- usually some form of processed image data. This data is regenerated during Player Build, and may be safely discarded otherwise. Use this method to clear the data store to avoid large files in your project.

RemoveAt(XRReferenceImageLibrary, Int32)

Removes the XRReferenceImage at index.

Declaration

public static void RemoveAt(this XRReferenceImageLibrary library, int index)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.
Int32	index	The index in the list of images to remove.

Exceptions

Type	Condition
ArgumentNullException	Thrown if library is null.
IndexOutOfRangeException	Thrown if index is not between 0 and library.count - 1.

SetDataForKey(XRReferenceImageLibrary, String, Byte[])

Associate binary data with a string key.

Declaration

public static void SetDataForKey(this XRReferenceImageLibrary library, string key, byte[] data)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.
String	key	The key which can be used to later retrieve data.
Byte[]	data	The data to associate with key.

Remarks

Providers use this to associate provider-specific data with the library. During Player Build (in an IPreprocessBuildWithReport.OnPreprocessBuild callback), the data store is first cleared. Each enabled provider then has an opportunity to add one or more entries for itself.

Providers can use this to store a serialized version of the image library specific to that provider. Retrieve data with dataStore.

Exceptions

Type	Condition
ArgumentNullException	Thrown if key is null.

SetName(XRReferenceImageLibrary, Int32, String)

Sets the XRReferenceImage.name value on the XRReferenceImage at index. This value is read-only in the Player; it can only be modified in the Editor.

Declaration

public static void SetName(this XRReferenceImageLibrary library, int index, string name)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.
Int32	index	The index of the reference image within the library to modify.
String	name

Exceptions

Type	Condition
ArgumentNullException	Thrown if library is null.
IndexOutOfRangeException	Thrown if index is not between 0 and library.count - 1.

SetSize(XRReferenceImageLibrary, Int32, Vector2)

Sets the XRReferenceImage.size value on the XRReferenceImage at index. This value is read-only in the Player; it can only be modified in the Editor.

Declaration

public static void SetSize(this XRReferenceImageLibrary library, int index, Vector2 size)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.
Int32	index	The index of the reference image within the library to modify.
UnityEngine.Vector2	size

Exceptions

Type	Condition
ArgumentNullException	Thrown if library is null.
IndexOutOfRangeException	Thrown if index is not between 0 and library.count - 1.

SetSpecifySize(XRReferenceImageLibrary, Int32, Boolean)

Sets the XRReferenceImage.specifySize value on the XRReferenceImage at index. This value is read-only in the Player; it can only be modified in the Editor.

Declaration

public static void SetSpecifySize(this XRReferenceImageLibrary library, int index, bool specifySize)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.
Int32	index	The index of the reference image within the library to modify.
Boolean	specifySize	Whether XRReferenceImage.size is specified.

Exceptions

Type	Condition
ArgumentNullException	Thrown if library is null.
IndexOutOfRangeException	Thrown if index is not between 0 and library.count - 1.

SetTexture(XRReferenceImageLibrary, Int32, Texture2D, Boolean)

Set the texture on the reference image.

Declaration

public static void SetTexture(this XRReferenceImageLibrary library, int index, Texture2D texture, bool keepTexture)

Parameters

Type	Name	Description
XRReferenceImageLibrary	library	The XRReferenceImageLibrary being extended.
Int32	index	The reference image index to modify.
UnityEngine.Texture2D	texture	The texture to set.
Boolean	keepTexture	Whether to store a strong reference to the texture. If true, the texture will be available in the Player. Otherwise, XRReferenceImage.texture will be set to null.

Exceptions

Type	Condition
ArgumentNullException	Thrown if library is null.
IndexOutOfRangeException	Thrown if index is not between 0 and library.count - 1.
