| Parameter | Description | 
|---|---|
| src | Resource to read the data from. | 
| size | Size in bytes of the data to be retrieved from the ComputeBuffer or GraphicsBuffer. | 
| offset | Offset in bytes in the ComputeBuffer or GraphicsBuffer. | 
| mipIndex | Index of the mipmap to be fetched. | 
| dstFormat | Target TextureFormat of the data. If the target format is different from the format stored on the GPU, the conversion is automatic. | 
| x | Starting X coordinate in pixels of the Texture data to be fetched. | 
| width | Width in pixels of the Texture data to be fetched. | 
| y | Starting Y coordinate in pixels of the Texture data to be fetched. | 
| height | Height in pixels of the Texture data to be fetched. | 
| z | Depth in pixels for Texture3D being fetched. Number of layers for TextureCube, TextureArray and TextureCubeArray. | 
| depth | Depth in pixels for Texture3D being fetched. Number of layers for TextureCube, TextureArray and TextureCubeArray. | 
Retrieves data asynchronously from a GPU resource.
