Function to get the height of a Font in pixels.

The member function Font::Size and std::abs on Font::Height don't work perfectly.

Use Canvas::TextHeight on a random string instead.


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

const int GetFontHeight(const TImage * const image)

{

  // const_cast necessary as the VCL is not const-correct. Grumble, grumble...

  return const_cast<TImage*>(image)->Canvas->TextHeight("x");

}
