Hi,
I have simple code that renders image using osgviewer. I am able to render
the image successfully with the code. My problem now is the size of the image
is reduced. for example the original size of the image is 4683 * 3035, the
image is reduced to 4096 * 3035. Is this expected behaviour or is there
anything I need to add in my code. I have added my code.
//required header files
int main(int argc,char**argv)
{
osg::ref_ptr<osg::Image> image;
image = osgDB::readImageFile("C:\\Users\\mcw\\Desktop\\DemModel.tif.gdal");
std::cout << "Image info are " << image->s() << "\n" <<image->t()
<<"\n" <<image->r() << std::endl;
if (!(image.valid()))
{
std::cout << "Unable to read image file " << std::endl;
getchar();
return 0;
}
osg::ref_ptr<osg::Geode> geode =(osg::createGeodeForImage(image));
osg::Texture2D *texture = new osg::Texture2D();
texture->setFilter(osg::Texture::MIN_FILTER, osg::Texture::LINEAR);
texture->setFilter(osg::Texture::MAG_FILTER, osg::Texture::LINEAR);
texture->setWrap(osg::Texture::WRAP_R, osg::Texture::REPEAT);
texture->setResizeNonPowerOfTwoHint(false);
texture->setImage(image);
texture->setBorderColor(osg::Vec4d(0.4f, 0.5f, 0.6f, 1.0f));
osg::StateSet* stateset = new osg::StateSet;
stateset->setTextureAttributeAndModes(0, texture,
osg::StateAttribute::ON);
geode->setStateSet(stateset);
osgViewer::Viewer viewer;
viewer.setSceneData(geode.get());
getchar();
return viewer.run();
}
...
Thank you!
Cheers,
Uma
