[Marble-devel] Kml GroundOverlay

[Konrad Enzensberger]

Hi,

like posted before, the rotation settings in Kml tag:
<GroundOverlay>
    <LatLonBox>
        <rotation>...

does not have any effect, the image is not rotated.
Because of this is made some modifications to GeometryLayer.cpp :.
createGraphicsItemFromOverlay( const GeoDataOverlay *overlay )
{
    if ( overlay->nodeType() == GeoDataTypes::GeoDataGroundOverlayType ) {
    ...
    //new
    GeoDataLatLonBox box = groundOverlay->latLonBox();
    qreal rotation = box.rotation(GeoDataCoordinates::Degree);
    if(rotation!=0)
    {
        QString qsImg = groundOverlay->absoluteIconFile();
        QImage img(qsImg);
        if(!img.isNull())
        {
            QMatrix rm;
            rm.rotate(rotation);
            img = img.transformed(rm);
            imageItem->setImage( img );
        }
    }//new end
    item = imageItem;
}

This works for me because all my images have same x/y resolution.
The image is now rotated like set in kml file.
 
But for other images (different x/y resolution) , the GeoDataLatLonBox coordinates also have to be rotated,
i think,
