Code:
#include <osg/Notify>
#include <osgViewer/Viewer>
#include <osgEarthUtil/EarthManipulator>
#include <osgEarthUtil/ExampleResources>
#include <osgEarthAnnotation/ModelNode>
#include <osgEarthAnnotation/PlaceNode>
int main()
{
int argc = 2;
char* argv[2];
argv[0] = "*.exe";
argv[1] =
"D:\\RUNTIME\\osgearth-3.0.1-2.4\\Release\\tests\\gdal_tiff.earth";
osg::ArgumentParser arguments( &argc, argv );
osg::ref_ptr<osgViewer::Viewer> viewer=new osgViewer::Viewer(arguments);
osg::ref_ptr<osg::Group> group=new osg::Group;
viewer->getDatabasePager()->setUnrefImageDataAfterApplyPolicy( false,
false );
osg::ref_ptr<osgEarth::Util::EarthManipulator> em=new
osgEarth::Util::EarthManipulator;
viewer->setCameraManipulator(em);
osg::ref_ptr<osg::Node>
earthFileNode=osgEarth::Util::MapNodeHelper().load(arguments,viewer);
osgEarth::MapNode* mapNode =
osgEarth::MapNode::findMapNode(earthFileNode);
group->addChild(earthFileNode);
//add Annotation:
osgEarth::Symbology::Style AnnotationStyle;
AnnotationStyle.getOrCreate<osgEarth::IconSymbol>()->url()->setLiteral(
"D:/EARTH/data/images/PNG/placemark32.png" );
AnnotationStyle.getOrCreate<osgEarth::Annotation::TextSymbol>()->size()
=50.0;
const osgEarth::SpatialReference*
geoSRS=mapNode->getMapSRS()->getGeographicSRS();
osg::ref_ptr<osgEarth::Annotation::PlaceNode> pn=new
osgEarth::Annotation::PlaceNode(mapNode,osgEarth::GeoPoint(geoSRS, -74.00,
40.71), "New York", AnnotationStyle);
group->addChild(pn);
//output Annotation:
osgDB::Registry::instance()->writeNode(*pn,"Annotation.ive",osgDB::Registry::instance()->getOptions());
if ( earthFileNode )
{
viewer->setSceneData( group );
viewer->getCamera()->setNearFarRatio(0.00002);
viewer->getCamera()->setSmallFeatureCullingPixelSize(-1.0f);
viewer->run();
}
return 0;
}
then, i get errer:
Error writing IVE image: StateSet::write(): Unknown StateAttribute:
VirtualProgram
How can i ?
