Stream image that is returned when no IRingBuffer interface is available.
This behaves almost as a MappedImage. The difference is that if the pixel buffer switches underneath, this image still points to the pixel buffer it was created on. The CvbMappedImage will point to the new location.
Switching pixel buffers commonly occurs on driver related DeviceImages like the VinImage from the VinDevice. If available on a Device, prefer the RingBufferImage.
| BufferImage | ( | Device | device | ) |
Creates a new BufferImage from the given device .
| device | Device that has IImageVPA interface. |
| BufferImage | ( | Device | device, |
| ImageLayout | layout | ||
| ) |
Creates a new BufferImage from the given device and layout information.
Attention: no security checks are performed: incompatible device Images will lead to access violation on image data access..
This version is faster as no analysis of the given device image needs to be done.
| device | Device that has IImageVPA interface. |
| layout | Layout information of the device image. |
|
protectedvirtual |
Unregisters the disposing event if this object is disposed before its parent.
| disposing | true if called from IDisposable interface; false if called from finalizer. |
