示例1: testAltitude

{
QFETCH(qreal, alt);
GeoDataLatLonAltBox box;
box.setMinAltitude(alt);
QCOMPARE(box.minAltitude(), alt);
box.setMaxAltitude(alt);
QCOMPARE(box.maxAltitude(), alt);
}示例2: fromLineString
GeoDataLatLonAltBox GeoDataLatLonAltBox::fromLineString( const GeoDataLineString& lineString )
{
// If the line string is empty return a boundingbox that contains everything
if ( lineString.size() == 0 ) {
return GeoDataLatLonAltBox();
}
const qreal altitude = lineString.first().altitude();
GeoDataLatLonAltBox temp ( GeoDataLatLonBox::fromLineString( lineString ), altitude, altitude );
qreal maxAltitude = altitude;
qreal minAltitude = altitude;
// If there's only a single node stored then the boundingbox only contains that point
if ( lineString.size() == 1 ) {
temp.setMinAltitude( minAltitude );
temp.setMaxAltitude( maxAltitude );
return temp;
}
QVector<GeoDataCoordinates>::ConstIterator it( lineString.constBegin() );

for ( ; it != itEnd; ++it )
{
// Get coordinates and normalize them to the desired range.
const qreal altitude = (it)->altitude();
// Determining the maximum and minimum latitude
if ( altitude > maxAltitude ) maxAltitude = altitude;
if ( altitude < minAltitude ) minAltitude = altitude;
}
