Ian has a point here, the correct and best way to do this would be to use the
raw image data and then interpolate/filter this.
However, if you want to stretch/shrink the jpeg file to the window, the
following code snippet should do it. Note this does really horrible
interpolation though:
#include <fltk/Window.h>
#include <fltk/run.h>
#include <fltk/SharedImage.h>
using namespace fltk;
int main(){
register_images();
Window win(600, 800, "Test Window");
win.box(SharedImage::get("samplemine.jpg"));
win.show();
return run();
}
