Interface IPixelResampler

All Superinterfaces:

Serializable

All Known Subinterfaces:

IRGB32PixelResampler, ISimplePixelResampler

All Known Implementing Classes:

RGB32PixelResampler, SimplePixelResampler

public interface IPixelResampler
extends Serializable

Provides access to members that control a pixel resampler.

Remarks

IPixelResampler is a generic interface that is supported by a pixel resampler, which is used for RasterXformer.

The concrete pixel resampler is SimplePixelResampler, user can create a custom pixel resampler by implementing IPixelResampler interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

int	getWindowSize() The resampling window size in terms of number of source pixels.
boolean	isDownSampling() Indicates if this is a down sampling only type of resampler.
boolean	isLinearScaling() Indicates if only linear scaling is necessary.
boolean	isSupportLinearScaling() Indicates if this resampler can accept simplified point array for simple linear scaling.
void	resample(int iCol, int iRow, int nCols, int nRows, _WKSPoint points, double ulx, double uly, double dx, double dy, IPixelBlock pSrcPixelBlock, IPixelBlock pDstPixelBlock) Resamples an input pixel block into an output pixel block.
void	setLinearScaling(boolean pLinearScaling) Indicates if only linear scaling is necessary.
