Class MutableRuntimeReferenceImageLibraryExtensions
Extension methods for MutableRuntimeReferenceImageLibrary.
Namespace: UnityEngine.XR.ARFoundation
Syntax
public static class MutableRuntimeReferenceImageLibraryExtensions
Methods
ScheduleAddImageJob(MutableRuntimeReferenceImageLibrary, Texture2D, String, Nullable<Single>, JobHandle)
Asynchronously adds texture
to library
.
Declaration
[Obsolete("Use ScheduleAddImageWithValidationJob instead. (2020-10-20)")]
public static JobHandle ScheduleAddImageJob(this MutableRuntimeReferenceImageLibrary library, Texture2D texture, string name, float? widthInMeters, JobHandle inputDeps = default(JobHandle))
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
This method is deprecated. Use ScheduleAddImageWithValidationJob(MutableRuntimeReferenceImageLibrary, Texture2D, String, Nullable<Single>, JobHandle) instead.
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(MutableRuntimeReferenceImageLibrary, Texture2D, String, Nullable<Single>, JobHandle) JobHandle
as the input dependency to the next
ScheduleAddImageJob(MutableRuntimeReferenceImageLibrary, Texture2D, String, Nullable<Single>, JobHandle); they can be processed concurrently.
The bytes of the texture
are copied, so the texture may be safely
destroyed after this method returns.

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 AddReferenceImageJobState can be used to query for job completion and whether the addition was successful.
