Detailed Description

AsyncGPUReadback 2 mat helper. v 1.0.1.

Efficiently process the conversion to Mat format for Texture classes for which the GetPixels method cannot be used, such as RenderTexture and external texture format Texture2D.

By setting outputColorFormat to RGBA processing that does not include extra color conversion is performed.

Member Function Documentation

◆ _Initialize()

virtual IEnumerator OpenCVForUnity.UnityUtils.Helper.AsyncGPUReadback2MatHelper._Initialize ( )

protectedvirtual

Initializes this instance by coroutine.

◆ CancelInitCoroutine()

virtual void OpenCVForUnity.UnityUtils.Helper.AsyncGPUReadback2MatHelper.CancelInitCoroutine ( )

protectedvirtual

Cancel Init Coroutine.

◆ DidUpdateThisFrame()

virtual bool OpenCVForUnity.UnityUtils.Helper.AsyncGPUReadback2MatHelper.DidUpdateThisFrame ( )

virtual

Indicates whether the readback buffer of the frame has been updated.

Implements OpenCVForUnity.UnityUtils.Helper.ISource2MatHelper.

◆ Dispose()

virtual void OpenCVForUnity.UnityUtils.Helper.AsyncGPUReadback2MatHelper.Dispose ( )

virtual

Releases all resource used by the AsyncGPUReadback2MatHelper object.

Call Dispose when you are finished using the AsyncGPUReadback2MatHelper. The Dispose method leaves the AsyncGPUReadback2MatHelper in an unusable state. After calling Dispose, you must release all references to the AsyncGPUReadback2MatHelper so the garbage collector can reclaim the memory that the AsyncGPUReadback2MatHelper was occupying.
