Class SeRasterScanLineGenerator

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

public class SeRasterScanLineGenerator
extends java.lang.Object

SeRasterScanLineGenerator.java: Image scan line generator from java.awt.Image object. Given SDE raster attribute info, Java AWT Image and other parameters. This class will automatically generate image scan_line with or without bit_mask that is ready to be use on SeInsert or SeUpdate operation via scan_line_mode.

Since:

ArcSDE 9.0

Constructor Detail

SeRasterScanLineGenerator

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

Constructs SeRasterScanLineGenerator object.

Top of SeRasterScanLineGenerator class.

Parameters:

rasAttr - a SeRasterAttr value

numScanLinesPerCall - an int value

Method Detail

hasBitMask

public boolean hasBitMask()

Return true if bit mask exist.

Returns:

a boolean value

getBitMaskData

public byte[] getBitMaskData()

Gets scan line's bit mask data, if exist. Else return null

Returns:

an byte[] value

getScanLineData

public byte[] getScanLineData()

Gets scan lines pixel data.

Returns:

an byte[] value

getNumLines

public int getNumLines()
                throws java.lang.Exception

Gets number of scan lines. Return the next set of ScanLines from AWT Image and return mNumLines. Return 0 if all done.

Returns:

an int value of number of scan lines.

Throws:

java.lang.Exception

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:

• MASK_ALL_ON (Default)
• MASK_ALL_OFF
• MASK_TILE_BOUNDARY
