Class IPixelBlock3Proxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.datasourcesraster.IPixelBlock3Proxy

All Implemented Interfaces:

IPixelBlock3, Externalizable, Serializable

public class IPixelBlock3Proxy
extends com.esri.arcgis.interop.Dispatch
implements IPixelBlock3, Serializable

Provides access to members that control a PixelBlock.

Description

The IPixelBlock3 interface provides all the functionality of IPixelBlock interface, plus more properties on mask based NoData and SafeArray handling.

Basically, there are two ways to work with NoData mask and pixel values. They are by value (PixelData and NoDataMask properties) and by reference (PixelDataByRef and NoDataMaskByRef). Normally passing pixel values by reference is recommented since it saves memory. However for Java and .Net, passing by value (PixelData) should be used.
