class CanvasFactoryPixelPyramid in Tinman.Terrain.Tools

An ICanvasFactory for visualizing IPixelPyramid objects.

sealed class

CanvasFactoryPixelPyramid

extends

CanvasFactory

Configuration

ToConfig

Returns the configuration value that describes this object.

public override method	ToConfig ()
type	ConfigValue
returns		[not-null]	The configuration value.
implements	CanvasFactory.ToConfig

Remarks:

All configurable objects need to implement this interface. For simple types, it is preferable to delegate to ToValue.

The returned value may be of type Invalid, which means that this object in its current state cannot be described with the configuration API.

Before returning the resulting configuration value, Cache must be called on it, passing this IConfigurable object as parameter.

Public / Attributes

BlockSize

Size of a canvas block.

public property	BlockSize { get set }
type	int32
value	[>0]	The block size, in canvas raster samples.
inherited	CanvasFactory.BlockSize

Remarks:

For PixelIsPoint semantics, the block size is a power of two plus one. For PixelIsArea semantics, the block size is a power of two.

Canvas.BlockCoverage

ColorError

Background color to use for pyramid tiles resulting from Error.

public property	ColorError { get set }
type	int64
value		The background color to use.

Remarks:

Set to 0 to produce the same tile data as for Empty.

Defaults to Red.

ColorVoid

Background color to use for pyramid tiles resulting from Void.

public property	ColorVoid { get set }
type	int64
value		The background color to use.

Remarks:

Set to 0 to produce the same tile data as for Empty.

Defaults to Magenta.

Georef

Returns georeferencing information.

public override property	Georef { get }
type	Raster
value		The georeferencing object or null if no georeferencing is available.
implements	CanvasFactory.Georef

LifecycleState

Returns the lifecycle state of this object.

public virtual property	LifecycleState { get }
type	LifecycleState
value		The lifecycle state.
inherited	Disposable.LifecycleState

Map

Returns a MapInfo value that describes the used map raster.

public override property	Map { get }
type	MapInfo
value		The map info value.
implements	CanvasFactory.Map

PixelPyramid

The pixel pyramid to use.

public property	PixelPyramid { get }
type	IPixelPyramid
value	[not-null]	The pixel pyramid instance.

SampleLayers

Returns the layers that are defined in the samples returned by GetSample.

public virtual property	SampleLayers { get }
type	HeightmapLayer
value		The sample layers.
inherited	CanvasFactory.SampleLayers

SampleRange

Returns the vertical range for the samples returned by GetSample.

public virtual property	SampleRange { get }
type	VerticalRange
value		The sample range, in Metre.
inherited	CanvasFactory.SampleRange

Public / Constructors

CanvasFactoryPixelPyramid

Creates a new instance of CanvasFactoryPixelPyramid.

public constructor	CanvasFactoryPixelPyramid ([Owner] IPixelPyramid pixelPyramid)
params	pixelPyramid	[not-null]	The pixel pyramid to use.

Public / Methods

AcquireTry

Acquires a strong reference to this disposable object.

[OwnerReturn, ThreadSafe]
public method	AcquireTry ()
type	IDisposable
returns			this if a new strong reference has been acquired, null if this object is already being disposed.
inherited	Disposable.AcquireTry

Remarks:

The object will not be actually disposed by calls to Dispose when there is at least one strong reference left. Code that calls the AcquireTry method is responsible for calling the Dispose method accordingly.

This method is not intended to be used in performance-critical code. It should only be used to high-level resource management.

CreateCanvas

Creates a new instance of Canvas.

[OwnerReturn]
public override method	CreateCanvas ([Owner] ICanvasContent content)
type	Canvas
params	content	[not-null]	The canvas content object to use.
returns		[not-null]	The canvas object.
implements	CanvasFactory.CreateCanvas

Dispose

Releases all resources held by this object if there are no more strong references to it, decrements the reference counter by one otherwise.

[Dispose, OwnerThis, ThreadSafe]
public method	Dispose ()
inherited	Disposable.Dispose

Remarks:

The Dispose method silently returns if the object has already been disposed.

GetSample

Returns a sample that describes the data that is stored at the given location.

[ThreadSafe]
public override method	GetSample (CubemapFaceCoordsI coords)
type	HeightmapSample
params	coords		The cubemap face coordinates.
returns			An HeightmapSample value that describes the stored data.
overrides	CanvasFactory.GetSample
