Inheritance

Object

MutableRuntimeReferenceImageLibraryExtensions

Namespace: UnityEngine.XR.ARFoundation

Syntax

public static class MutableRuntimeReferenceImageLibraryExtensions

Methods

ScheduleAddImageJob(MutableRuntimeReferenceImageLibrary, Texture2D, String, Nullable<Single>, JobHandle)

Asynchronously adds texture to library.

Declaration

public static JobHandle ScheduleAddImageJob(this MutableRuntimeReferenceImageLibrary library, Texture2D texture, string name, float? widthInMeters, JobHandle inputDeps = null)

Parameters

Type	Name	Description
MutableRuntimeReferenceImageLibrary	library	The MutableRuntimeReferenceImageLibrary being extended.
Texture2D	texture	The Texture2D to use as image target.
String	name	The name of the image.
Nullable<Single>	widthInMeters	The physical width of the image, in meters.
JobHandle	inputDeps	Input job dependencies (optional).

Returns

Type	Description
JobHandle	A JobHandle which can be used to chain together multiple tasks or to query for completion. May be safely discarded.

Remarks

Image addition can take some time (several frames) due to extra processing that must occur to insert the image into the library. This is done using the Unity Job System. The returned JobHandle can be used to chain together multiple tasks or to query for completion, but may be safely discarded if you do not need it.

This job, like all Unity jobs, can have dependencies (using the inputDeps). If you are adding multiple images to the library, it is not necessary to pass a previous ScheduleAddImageJob JobHandle as the input dependency to the next ScheduleAddImageJob; they can be processed concurrently.

The bytes of the texture are copied, so the texture may be safely destroyed after this method returns.

Exceptions

Type	Condition
InvalidOperationException	Thrown if is null.
ArgumentNullException	Thrown if texture is null.
InvalidOperationException	Thrown if texture is not readable.
