Member Function Documentation

virtual QCamFrame QCam::yuvFrame

(

)

const [pure virtual]

return the frame in yuv 420P format.

it is the native format used by all algoithms.

Implemented in QCamAdd, QCamAutoAlign, QCamMax, and QCamV4L.

virtual void QCam::resize

(

const QSize &

s

)

[pure virtual]

try to resize the current frame.

it can failed. size() must be called to know the real new size.

Implemented in QCamAdd, QCamAutoAlign, QCamMax, and QCamV4L.

const QSize * QCam::getAllowedSize

(

)

const [pure virtual]

return an array of supported size of th capture window.

The las entry of the table must be a null size (=QSize(0,0)). A minimal empty emplementation is given for no resizable QCam

Implemented in QCamAdd, QCamAutoAlign, QCamMax, QCamV4L, and QCamVesta.

void QCam::setProperty	(	const string &	prop,
		const string &	val,
		bool	resetCapture = false
	)

Set the value of a properties.

Properties are dumped is file "<dirName>/properties.txt" in sequence capture mode. Properties are dumped is file "<fileName>.properties" in snapshot capture mode.

void QCam::newFrameAvaible

(

)

[protected]

Must be called when a new YUV frame is avaible.

It is used by frame() to opimize conversion from YUV to QImage.
