IRasterXformer Interface

Provides access to members that control raster transformer.

Members

	Name	Description
	ApproximationTolerance	The current approximation error tolerance in number (fraction) of pixels.
	PixelResampler	The current raster resampler.
	Raster	The raster to be transformed.
	Read	Reads a pixel block.
	Update	Updates the raster transformer with the changed raster.

IRasterXformer.ApproximationTolerance Property

The current approximation error tolerance in number (fraction) of pixels.

Public Property ApproximationTolerance As Double

public double ApproximationTolerance {get; set;}

Remarks

The tolerance, used in geodata xform approximation. The unit is in output space.

IRasterXformer.PixelResampler Property

The current raster resampler.

Public Property PixelResampler As IPixelResampler

public IPixelResampler PixelResampler {get; set;}

IRasterXformer.Raster Property

The raster to be transformed.

Public WriteOnly Property Raster

public void Raster {set;}

IRasterXformer.Read Method

Reads a pixel block.

Public Sub Read ( _
    ByVal tlc As IPnt, _
    ByVal pPixelBlock As IPixelBlock _
)

public void Read (
    IPnt tlc,
    IPixelBlock pPixelBlock
);

Remarks

Read the pixel block after applying the geodata transformation.

IRasterXformer.Update Method

Updates the raster transformer with the changed raster.

Public Sub Update ( _
    ByVal pRaster As IRaster _
)

public void Update (
    IRaster pRaster
);

Classes that implement IRasterXformer

Classes	Description
RasterXformer	A raster transformer class.

Remarks

The IRasterXformer interface is used to create a RasterXformer object from a Raster.

Creating a RasterXformer object, a GeodataXform, a PixelResampler and a PixelReader must be set.

To create a RasterXformerfrom**aRaster, use _IRasterXformer_::_Raster_ method which contains a GeodataXform, a default PixelResampler and a PixelReader**

To create a RasterXformer without using Raster, IRasterXformer2 interface should be used.
