Special device image.
This image points to the image data that is currently processed. It is not necessary the newest acquired image. It points to the image buffer that is returned due to the last grab synchronization method (i.e. Wait
method).
Use this image only in the same thread context in which you grab handling occurs. The object will stay the same, but the underlying buffer changes when the synchronization method returns successfully. If you need the image in a parallel context copy the image (Image.Copy)
|
protected |
Creates the VideoImage.
No memory pressure is performed by this image as the device holds the memory. It is guessed via the IRingBuffer interface.
device | Device object (and thus the image handle). |
|
protectedvirtual |
Change the dispose handling by just detaching from the native handle.
disposing | true when called via IDisposable.Dispose, false when called by the finalizer. |
Reimplemented from Image.
|
getset |
Gets whether this image is now standalone (not connected to a device anymore.
Disconnected images point to the last acquired image in the device's ring buffer. But no other access is possible on these kind of images.
