Detailed Description

A node in a multi-resolution image tree.

vtkGeoImageNode contains an image tile in a multi-resolution image tree, along with metadata about that image's extents.

Member Function Documentation

static vtkGeoImageNode* vtkGeoImageNode::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkGeoTreeNode.

static int vtkGeoImageNode::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type 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 vtkGeoTreeNode.

virtual int vtkGeoImageNode::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 vtkGeoTreeNode.

static vtkGeoImageNode* vtkGeoImageNode::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkGeoTreeNode.

virtual vtkObjectBase* vtkGeoImageNode::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkGeoTreeNode.

vtkGeoImageNode* vtkGeoImageNode::NewInstance

(

)

const

Reimplemented from vtkGeoTreeNode.

void vtkGeoImageNode::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 vtkGeoTreeNode.

vtkGeoImageNode* vtkGeoImageNode::GetChild

(

int

idx

)

Every subclass implements these methods returning the specific type. This is easier than templating.

vtkGeoImageNode* vtkGeoImageNode::GetParent

(

)

Every subclass implements these methods returning the specific type. This is easier than templating.

vtkImageData* vtkGeoImageNode::GetImage

(

)

Get the image tile.

void vtkGeoImageNode::SetImage

(

vtkImageData *

image

)

Get the image tile.

vtkTexture* vtkGeoImageNode::GetTexture

(

)

Get the image tile.

void vtkGeoImageNode::SetTexture

(

vtkTexture *

texture

)

Get the image tile.

void vtkGeoImageNode::CropImageForTile	(	vtkImageData *	image,
		double *	imageLonLatExt,
		const char *	prefix = 0
	)

This crops the image as small as possible while still covering the patch. The Longitude Latitude range may get bigger to reflect the actual size of the image. If prefix is specified, writes the tile to that location.

void vtkGeoImageNode::LoadAnImage

(

const char *

prefix

)

This loads the image from a tile database at the specified location.

virtual void vtkGeoImageNode::ShallowCopy

(

vtkGeoTreeNode *

src

)

[virtual]

Shallow and Deep copy.

Reimplemented from vtkGeoTreeNode.

virtual void vtkGeoImageNode::DeepCopy

(

vtkGeoTreeNode *

src

)

[virtual]

Shallow and Deep copy.

Reimplemented from vtkGeoTreeNode.

virtual bool vtkGeoImageNode::HasData

(

)

[virtual]

Returns whether this node has valid data associated with it, or if it is an "empty" node.

Reimplemented from vtkGeoTreeNode.

virtual void vtkGeoImageNode::DeleteData

(

)

[virtual]

Deletes the data associated with the node to make this an "empty" node. This is performed when the node has been unused for a certain amount of time.

Reimplemented from vtkGeoTreeNode.

int vtkGeoImageNode::PowerOfTwo

(

int

val

)
