Constructor & Destructor Documentation

VideoFrame::VideoFrame

(

VideoArray< coeff > *

va

)

Constructor. Creates an empty image with given dimensions. Unlike in the StillImage class the memory holding the coefficients is held externally and contains all frames. The VideoArray object automatically returns data from the frame which has previously been set as the current one. No boundary checking is done!

Parameters:

va	a pointer to the VideoArray holding all frames

virtual VideoFrame::~VideoFrame

(

void

)

[virtual]

Destructor. Deallocates objects.

Member Function Documentation

virtual Image* VideoFrame::clone

(

void

)

const [virtual]

Produce a copy. Every dynamically object will be cloned rather than passing on the reference. This operation returns a StillImage and not a VideoFrame, since a VideoFrame always depends on the external VideoArray, so that the copy would only alias to the same external memory!

Returns:

the new, copied object.

Reimplemented from StillImage.
