DrawGlobePlus is a VCL graphics code snippet to draw a globe with a plus on it.

DrawGlobePlus assumes that you have already defined the DrawGlobe function.


#include <ExtCtrls.hpp>



//From http://www.richelbilderbeek.nl/CppDrawGlobePlus.htm

void DrawGlobePlus(

  TImage * const image,

  const unsigned char red,

  const unsigned char green,

  const unsigned char blue)

{

  DrawGlobe(image,red,green,blue);

  const int height = image->Picture->Bitmap->Height;

  const int width  = image->Picture->Bitmap->Width;

  image->Canvas->Pen->Width = height / 10;

  image->Canvas->Pen->Color = static_cast<TColor>(RGB(red,green,blue));

  image->Canvas->MoveTo(1 * width / 4,height / 2);

  image->Canvas->LineTo(3 * width / 4,height / 2);

  image->Canvas->MoveTo(width / 2,1 * height / 4);

  image->Canvas->LineTo(width / 2,3 * height / 4);

}
