示例1: qwtScaledBoundingRect
static inline QRectF qwtScaledBoundingRect(
const QwtGraphic &graphic, const QSizeF size )
{
QSizeF scaledSize = size;
if ( scaledSize.isEmpty() )
scaledSize = graphic.defaultSize();
const QSizeF sz = graphic.controlPointRect().size();
double sx = 1.0;
if ( sz.width() > 0.0 )
sx = scaledSize.width() / sz.width();
double sy = 1.0;
if ( sz.height() > 0.0 )
sy = scaledSize.height() / sz.height();
return graphic.scaledBoundingRect( sx, sy );
