Member Function Documentation

template<typename T>

void osgEarth::ImageUtils::PixelVisitor< T >::accept

(

osg::Image *

image

)

[inline]

Traverse an image, and call this method on the superclass:

bool operator(const osg::Vec4& pixel);

If that method returns true, write the value back at the same location.

                                           {
                PixelReader _reader( image );
                PixelWriter _writer( image );
                for( int r=0; r<image->r(); ++r ) {
                    for( int t=0; t<image->t(); ++t ) {
                        for( int s=0; s<image->s(); ++s ) {
                            osg::Vec4f pixel = _reader(s,t,r);

Here is the caller graph for this function:

template<typename T>

void osgEarth::ImageUtils::PixelVisitor< T >::accept	(	const osg::Image *	src,
		osg::Image *	dest
	)		[inline]

Traverse an image, and call this method on the superclass:

bool operator(const osg::Vec4& srcPixel, osg::Vec4& destPixel);

If that method returns true, write destPixel back at the same location in the destination image.

                PixelReader _readerSrc( src );
