Detailed Description

DrawPixels is an osg::Drawable subclass which encapsulates the drawing of images using glDrawPixels.

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 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 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::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 osg::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.
