Class SeRasterScanLineProducer

java.lang.Object
  com.esri.sde.sdk.client.SeRasterScanLineProducer

All Implemented Interfaces:

SeRasterProducer

public class SeRasterScanLineProducer
extends java.lang.Object
implements SeRasterProducer

SeRasterScanLineProducer.java: SeRasterScanLineProducer class is implement as SeRasterProducer. The SeRasterConsumer.setScanLines() method provide the callback mechanism to continue feed the SeInsert or SeUpdate stream with raster data in the form of raster image_scan_lines.

Since:

ArcSDE 9.0

Constructor Detail

SeRasterScanLineProducer

public SeRasterScanLineProducer(SeRasterAttr rasAttr,
                                java.awt.Image awtImage,
                                int numScanLinesPerCall)

Constructs SeRasterScanLineProducer object.

Top of SeRasterScanLineProducer class.

Parameters:

rasAttr - a SeRasterAttr value

awtImage - a java.awt.Image value

numScanLinesPerCall - an int value

Method Detail

setBitMaskType

public void setBitMaskType(int method)

Sets bitmask type or automatic bitmask generating method. if the mask_mode in SeRasterAttr object is NOT set to true (ie, by calling SeRasterAttr.setMaskMode(true)), then any bitmask type setting is ignore, because no bitmask data will be generated.

Support the following bitmask_type:

• SeRasterScanLineGenerator.MASK_ALL_ON (Default)
• SeRasterScanLineGenerator.MASK_ALL_OFF
• SeRasterScanLineGenerator.MASK_TILE_BOUNDARY
