3.1.2 Image Pixel Coordinates

Image Pixel Coordinates

Image pixel coordinates are represented by class ImageCoords , which has an interface similar to WorldCoords :

 
// constructor - initialize null coordinates 
ImageCoords(); 
 
// constructor: initialize with (x, y
) 
ImageCoords(double x, double y); 
 
// constructor - parse X and Y in string format 
ImageCoords(const char* x_str, const char* y_str); 
Example: 
ImageCoords c1(123.456, 654.321); 
ImageCoords c2("123.456.", "654.321."); 
 
cout << "these coords should be the same (or very close):" << endl 
     << c1 << endl 
     << c2 << endl;

See ImageCoords(3) for more details.
