Constructor & Destructor Documentation

osg::DrawPixels::DrawPixels  
 

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

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::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 the 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.

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

compute the bounding box of the drawable.

Method must be implemented by subclasses.

Reimplemented from osg::Drawable.

virtual void osg::DrawPixels::drawImmediateMode State   state [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 osg::DrawPixels::getSubImageDimensions unsigned int &    offsetX,
unsigned int &    offsetY,
unsigned int &    width,
unsigned int &    height
const
 

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 the is that the namspace of a library is the same as the library name.

Reimplemented from osg::Drawable.
