void rec::robotino::com::Camera::setStreaming

(

bool

streaming

)

Turns the streaming on and off. Call this after connecting this object to a com object by calling setComId.

Parameters:

streaming

TRUE to turn streaming on.

Exceptions:

RobotinoException

If an error occured.

bool rec::robotino::com::Camera::isStreaming

(

)

const

Checks if streaming is enabled.

Returns:

TRUE if streaming is enabled.

Exceptions:

nothing.

void rec::robotino::com::Camera::setResolution	(	unsigned int	width,
		unsigned int	height
	)

Sets this camera to the given resolution (if possible)

Parameters:

	width	Requested image width
	height	Requested image height

Exceptions:

RobotinoException

if given com object is invalid.

void rec::robotino::com::Camera::resolution	(	unsigned int *	width,
		unsigned int *	height
	)			const

Returns the width and height set by setResolution

Parameters:

	width	Set to the currently requested image width
	height	Set to the currently requested image height

Exceptions:

RobotinoException

if given com object is invalid.

virtual void rec::robotino::com::Camera::imageReceivedEvent	(	const unsigned char *	data,
		unsigned int	dataSize,
		unsigned int	width,
		unsigned int	height,
		unsigned int	numChannels,
		unsigned int	bitsPerChannel,
		unsigned int	step
	)			[virtual]

Called when an image is received. Note: If Com is not initialized with useQueuedCallback=true this function is called from outside the applications main thread. This is extremely important particularly with regard to GUI applications.

Parameters:

	imageData	Contains the image data. You must not delete this buffer. Instead you should make a copy of this buffer within this function call.
	dataSize	Is the size of the jpeg data buffer.
	width	The number of pixels per line
	height	The number of lines
	numChannels	The number of channels
	numBitsPerChannel	The number of bits per channel
	step	The number of bytes per line. This is normally width * numChannels.

Exceptions:

nothing.
