Detailed Description

manages a stack of composited images

vtkImageStack manages the compositing of a set of images. Each image is assigned a layer number through its property object, and it is this layer number that determines the compositing order: images with a higher layer number are drawn over top of images with a lower layer number. The image stack has a SetActiveLayer method for controlling which layer to use for interaction and picking.

Member Function Documentation

static int vtkImageStack::IsTypeOf ( const char *  type )

static

virtual int vtkImageStack::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageSlice.

static vtkImageStack* vtkImageStack::SafeDownCast ( vtkObjectBase *  o )

static

virtual vtkObjectBase* vtkImageStack::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkImageSlice.

vtkImageStack* vtkImageStack::NewInstance

(

)

const

void vtkImageStack::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageSlice.

static vtkImageStack* vtkImageStack::New ( )

static

void vtkImageStack::AddImage

(

vtkImageSlice *

prop

)

Add an image to the stack. If the image is already present, then this method will do nothing.

void vtkImageStack::RemoveImage

(

vtkImageSlice *

prop

)

Remove an image from the stack. If the image is not present, then this method will do nothing.

int vtkImageStack::HasImage

(

vtkImageSlice *

prop

)

Check if an image is present. The returned value is one or zero.

vtkImageSliceCollection* vtkImageStack::GetImages ( )

inline

Get the list of images as a vtkImageSliceCollection.

Definition at line 64 of file vtkImageStack.h.

virtual void vtkImageStack::SetActiveLayer ( int  )

virtual

Set the active layer number. This is the layer that will be used for picking and interaction.

int vtkImageStack::GetActiveLayer ( )

inline

Set the active layer number. This is the layer that will be used for picking and interaction.

Definition at line 70 of file vtkImageStack.h.

vtkImageSlice* vtkImageStack::GetActiveImage

(

)

Get the active image. This will be the topmost image whose LayerNumber is the ActiveLayer. If no image matches, then NULL will be returned.

vtkImageMapper3D* vtkImageStack::GetMapper ( )

virtual

Get the mapper for the currently active image.

Reimplemented from vtkImageSlice.

vtkImageProperty* vtkImageStack::GetProperty ( )

virtual

Get the property for the currently active image.

Reimplemented from vtkImageSlice.

double* vtkImageStack::GetBounds ( )

virtual

Get the combined bounds of all of the images.

Reimplemented from vtkImageSlice.

void vtkImageStack::GetBounds ( double  bounds[6] )

inline

Get the combined bounds of all of the images.

Definition at line 87 of file vtkImageStack.h.

unsigned long int vtkImageStack::GetMTime ( )

virtual

Return the max MTime of all the images.

Reimplemented from vtkImageSlice.

unsigned long vtkImageStack::GetRedrawMTime ( )

virtual

Return the mtime of anything that would cause the rendered image to appear differently. Usually this involves checking the mtime of the prop plus anything else it depends on such as properties, mappers, etc.

Reimplemented from vtkImageSlice.

void vtkImageStack::ShallowCopy ( vtkProp *  prop )

virtual

Shallow copy of this prop. Overloads the virtual vtkProp method.

Reimplemented from vtkImageSlice.

void vtkImageStack::GetImages

(

vtkPropCollection *

)

For some exporters and other other operations we must be able to collect all the actors, volumes, and images. These methods are used in that process.

virtual int vtkImageStack::RenderOverlay ( vtkViewport *  viewport )

virtual

Support the standard render methods.

Reimplemented from vtkImageSlice.

virtual int vtkImageStack::RenderOpaqueGeometry ( vtkViewport *  viewport )

virtual

Support the standard render methods.

Reimplemented from vtkImageSlice.

virtual int vtkImageStack::RenderTranslucentPolygonalGeometry ( vtkViewport *  viewport )

virtual

Support the standard render methods.

Reimplemented from vtkImageSlice.

virtual int vtkImageStack::HasTranslucentPolygonalGeometry ( )

virtual

Does this prop have some translucent polygonal geometry?

Reimplemented from vtkImageSlice.

void vtkImageStack::ReleaseGraphicsResources ( vtkWindow *  win )

virtual

Release any resources held by this prop.

Reimplemented from vtkImageSlice.

void vtkImageStack::InitPathTraversal ( )

virtual

Methods for traversing the stack as if it was an assembly. The traversal only gives the view prop for the active layer.

Reimplemented from vtkProp3D.

vtkAssemblyPath* vtkImageStack::GetNextPath ( )

virtual

Methods for traversing the stack as if it was an assembly. The traversal only gives the view prop for the active layer.

Reimplemented from vtkProp.

int vtkImageStack::GetNumberOfPaths ( )

virtual

Methods for traversing the stack as if it was an assembly. The traversal only gives the view prop for the active layer.

Reimplemented from vtkProp.

virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS Used to construct assembly paths and perform part traversal.

Reimplemented from vtkProp.
