C++ (Cpp) SetScreenOrigin示例

示例#1

 TestProjection() {
     SetScreenOrigin(0, 0);
     SetScale(fixed(640) / (fixed(100) * 2));
     SetGeoLocation(GeoPoint(Angle::Degrees(fixed(7.7061111111111114)),
                             Angle::Degrees(fixed(51.051944444444445))));
     SetScreenSize(640, 480);
     UpdateScreenBounds();
 }

示例#2

void ChartProjection::set_projection(const PixelRect &rc, 
                                     const GeoPoint &center,
                                     const fixed radius)
