API / Documentation

The API is designed to be very simple to use C++ interface to various freely available libraries. A typical application would look something like:

MPEGSource source("myfilename");                             // Initialise the source
source.get_size(width, height);                              // get the size info
Image img(width,height);                                     // allocate memory for the image
ImageDisplayWindow win1(width,height,"window title");        // initialise the display
while (1) {
                source >> img1;          // acquire the image from the source
                win1 << img1;            // display the image in the window
}

Full API documentation is availabe for the two libraries:
