Detailed Description

Perform transformations (rotations, flips) on NDArrays.

Constructor & Destructor Documentation

NDPluginTransform()

NDPluginTransform::NDPluginTransform	(	const char *	portName,
		int	queueSize,
		int	blockingCallbacks,
		const char *	NDArrayPort,
		int	NDArrayAddr,
		int	maxBuffers,
		size_t	maxMemory,
		int	priority,
		int	stackSize,
		int	maxThreads = 1
	)

Constructor for NDPluginTransform; most parameters are simply passed to NDPluginDriver::NDPluginDriver.

After calling the base class constructor this method sets reasonable default values for all of the Transform parameters.

Parameters

[in]	portName	The name of the asyn port driver to be created.
[in]	queueSize	The number of NDArrays that the input queue for this plugin can hold when NDPluginDriverBlockingCallbacks=0. Larger queues can decrease the number of dropped arrays, at the expense of more NDArray buffers being allocated from the underlying driver's NDArrayPool.
[in]	blockingCallbacks	Initial setting for the NDPluginDriverBlockingCallbacks flag. 0=callbacks are queued and executed by the callback thread; 1 callbacks execute in the thread of the driver doing the callbacks.
[in]	NDArrayPort	Name of asyn port driver for initial source of NDArray callbacks.
[in]	NDArrayAddr	asyn port driver address for initial source of NDArray callbacks.
[in]	maxBuffers	The maximum number of NDArray buffers that the NDArrayPool for this driver is allowed to allocate. Set this to 0 to allow an unlimited number of buffers.
[in]	maxMemory	The maximum amount of memory that the NDArrayPool for this driver is allowed to allocate. Set this to 0 to allow an unlimited amount of memory.
[in]	priority	The thread priority for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in]	stackSize	The stack size for the asyn port driver thread if ASYN_CANBLOCK is set in asynFlags.
[in]	maxThreads	The maximum number of threads this driver is allowed to use. If 0 then 1 will be used.

Member Function Documentation

processCallbacks()

void NDPluginTransform::processCallbacks ( NDArray *  pArray )

virtual

Callback function that is called by the NDArray driver with new NDArray data.

Grabs the current NDArray and applies the selected transforms to the data. Apply the transforms in order.

Parameters

[in]

pArray

The NDArray from the callback.

Create a pointer to a structure of type NDArrayInfo_t and use it to get information about the input array.

Implements NDPluginDriver.
