Detailed Description

A class which implements the ImageSource interface as a source of QT movie Images.

Each image that is extracted from the QTSource class is a frame of the QT movie.

Note:

Assumes only one stream

Constructor & Destructor Documentation

QTSource::QTSource ( char * path )

Initialise an QT movie source. Parameters: path   The path and filename of the QT file to use. Definition at line 27 of file QTSource.cpp.

Member Function Documentation

void QTSource::get_size ( unsigned int & w, unsigned int & h ) [virtual]

Return the width and height of the QT. Parameters: w   The width of the QT frame. h   The height of the QT frame. Reimplemented from ImageSource. Definition at line 151 of file QTSource.cpp.

ImageSource & QTSource::operator>> ( Image & img ) [virtual]

Extract a frame of the QT movie. The Image could be colour or greyscale depending on the default palette type for this class. Parameters: img   The Image to be extracted to. Reimplemented from ImageSource. Definition at line 135 of file QTSource.cpp.

ImageSource & QTSource::operator>> ( ImageGrey & img ) [virtual]

Extract a frame of the QT movie to the greyscale Images brightness buffer. Parameters: img   The greyscale Image to be extracted to. Reimplemented from ImageSource. Definition at line 108 of file QTSource.cpp.

ImageSource & QTSource::operator>> ( ImageRGB & img ) [virtual]

Extract a frame of the QT movie to the colour Images data buffer. Parameters: img   The colour Image to be extracted to. Reimplemented from ImageSource. Definition at line 89 of file QTSource.cpp.

int QTSource::set_frame ( long frame_no )

Seek to point in file. Returns 0 if OK and -1 otherwise. Parameters: frame_no   frame number to set file pointer to Definition at line 163 of file QTSource.cpp.
