Interface IPixelFilter2

All Superinterfaces:

Serializable

All Known Implementing Classes:

ClipFilter, PansharpeningFilter, PixelFilterCollection

public interface IPixelFilter2
extends Serializable

Provides access to additional members that control a pixel filter.

Remarks

IPixelFilter2 is an optional interface for implementing a custom pixel filter. It will be called, if implemented, whenever the raster properties, including number of rows and columns, and extent, has changed, and right before a pixel block is to be filtered, with more information. A custom pixel filter can use the additional information to, for example, get the cellsize, and pre-fetch a related pixel block, and etc.

Product Availability

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

Method Summary

void	init(int nCols, int nRows, IEnvelope pExtent) Initializes this filter for a given area of interest.
void	initBlock(IPnt pTopLeft, int nBlkCols, int nBlkRows) Initialize this filter for a given pixel block.
