Class TLcdBILTileDecoder

java.lang.Object

com.luciad.format.raster.ALcdTileDecoder

com.luciad.format.raster.TLcdBILTileDecoder

All Implemented Interfaces:

ILcdTileDecoder, ILcdInputStreamFactoryCapable

public class TLcdBILTileDecoder
extends ALcdTileDecoder
implements ILcdTileDecoder

This ILcdTileDecoder decodes BIL (Band Interleaved by Line) tiles.

This class is thread-safe.

The current implementation supports 8-bits and 16-bits monochrome data, and 8-bits RGB data.

Constructor Details

TLcdBILTileDecoder

public TLcdBILTileDecoder(int aWidth,
 int aHeight,
 int aBandCount,
 int aBitCount,
 boolean aLittleEndian,
 int aSkipBytes,
 int aBandRowBytes,
 ColorModel aColorModel)

Creates a new TLcdBILTileDecoder.

Parameters:

aWidth - the tile width.

aHeight - the tile height.

aBandCount - the number of bands in the tile.

aBitCount - the number of bits in each band.

aLittleEndian - a flag that indicates if the byte order is little endian or big endian.

aSkipBytes - the number of bytes to skip before starting to read a tile.

aBandRowBytes - the number of bytes in the scanline of a single band.

aColorModel - the color model of the decoded tiles.

Method Details

readTileFromStream

protected ILcdTileInfo readTileFromStream(InputStream aInputStream,
 int aImageIndex,
 int aSubTileWidth,
 int aSubTileHeight,
 int aRowIndex,
 int aColumnIndex,
 ILcdBuffer aBuffer)
                                   throws TLcdCodecException

Description copied from class: ALcdTileDecoder

Reads a sub-tile from an input stream.

Specified by:

readTileFromStream in class ALcdTileDecoder

Parameters:

aInputStream - the input stream from which the tile data can be read.

aImageIndex - the index of the tile in the given input stream (if applicable).

aSubTileWidth - the width of the sub-tiles, expressed in pixels.

aSubTileHeight - the height of the sub-tiles, expressed in pixels.

aRowIndex - the row number of the sub-tile to be decoded.

aColumnIndex - the column number of the sub-tile to be decoded.

aBuffer - the buffer in which the decoded bytes will be stored.

Returns:

ILcdTileInfo information about the decoded tile.

Throws:

TLcdCodecException - in case of decoding problems.
