// The following example illustrates the use of the otb::DEMToImageGenerator class.
// The aim of this class is to generate an image from the srtm data (precising the start extraction
// latitude and longitude point). Each pixel is a geographic point and its intensity is
// the altitude of the point.
// If srtm doesn't have altitude information for a point, the altitude value is set at -32768 (value of the srtm norm).
//
// Let's look at the minimal code required to use this algorithm. First, the following header
// defining the \doxygen{otb}{DEMToImageGenerator} class must be included.
