Image

__int3264 Image

This determines the image object that has been assigned to the Common Vision RingBuffer Control.

The image must support at least the IRingBuffer interface.

Parameters

[in,out]

Image

Handle of the image object.

Returns

Image object handle.

LockMode

LockMode LockMode

Gets and sets the lockmode to be used.

Attention

You have to stop any acquisition before changing this property.

Parameters

[in,out]

LockMode

Sets the lockmode (for more details see: LockMode).

Returns

Current lock mode.

MaxNumBuffers

long MaxNumBuffers

Returns the maximum number of buffers that can be allocated by the driver.

Attention

The function may not be implemented by any driver.

Parameters

[out]

MaxNumBuffers

Gets the maximum number of buffers.

Returns

Maximum number of buffers.

NumBuffers

long NumBuffers

Used to retrieve or set the number of buffers used in the ringbuffer.

Setting this property may take some time as the buffers have to be allocated and initialized with zeros.

Attention

The Ringbuffer control creates a new image object from that call and this new image has to be set in other program parts (i.e. via the ImageUpdated event of the RingBuffer Control).

Parameters

[in,out]

NumBuffers

Number of buffers being used.

Returns

Retieve the number of buffers.
