Constructor & Destructor Documentation

DrawPixels::DrawPixels  ) 
 

DrawPixels::DrawPixels const DrawPixels drawimage,
const CopyOp copyop = CopyOp::SHALLOW_COPY
 

Copy constructor using CopyOp to manage deep vs shallow copy.

DrawPixels::~DrawPixels  )  [protected, virtual]
 


Member Function Documentation

virtual const char* osg::DrawPixels::className  )  const [inline, virtual]
 

return the name of the object's class type.

Must be defined by derived classes.

Reimplemented from osg::Drawable.

virtual Object* osg::DrawPixels::clone const CopyOp copyop  )  const [inline, virtual]
 

Clone an object, with Object* return type.

Must be defined by derived classes.

Implements osg::Object.

virtual Object* osg::DrawPixels::cloneType  )  const [inline, virtual]
 

Clone the type of an object, with Object* return type.

Must be defined by derived classes.

Implements osg::Object.

bool DrawPixels::computeBound  )  const [protected, virtual]
 

compute the bounding box of the drawable.

Method must be implemented by subclasses.

Reimplemented from osg::Drawable.

void DrawPixels::drawImplementation State state  )  const [virtual]
 

draw directly ignoring an OpenGL display list which could be attached.

This is the internal draw method which does the drawing itself, and is the method to override when deriving from Drawable.

Implements osg::Drawable.

const osg::Image* osg::DrawPixels::getImage  )  const [inline]
 

osg::Image* osg::DrawPixels::getImage  )  [inline]
 

const osg::Vec3& osg::DrawPixels::getPosition  )  const [inline]
 

osg::Vec3& osg::DrawPixels::getPosition  )  [inline]
 

void DrawPixels::getSubImageDimensions unsigned int &  offsetX,
unsigned int &  offsetY,
unsigned int &  width,
unsigned int &  height
const
 

bool osg::DrawPixels::getUseSubImage  )  const [inline]
 

virtual bool osg::DrawPixels::isSameKindAs const Object obj  )  const [inline, virtual]
 

Reimplemented from osg::Drawable.

virtual const char* osg::DrawPixels::libraryName  )  const [inline, virtual]
 

return the name of the object's library.

Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Reimplemented from osg::Drawable.

DrawPixels& osg::DrawPixels::operator= const DrawPixels  )  [inline, protected]
