Method Detail

setClassTraceOn

public static void setClassTraceOn(boolean aClassTraceOn)

Deprecated. This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Enables tracing for all instances of this class. If the argument is true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

Parameters:

aClassTraceOn - if true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

setTraceOn

public void setTraceOn(boolean aTraceOn)

Deprecated. This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Enables tracing for this class instance. Calling this method with either true or false as argument automatically turns off tracing for all other class instances for which setTraceOn has not been called. If the argument is false then only the informative, warning and error log messages are recorded.

Overrides:

setTraceOn in class ALcdTileDecoder

Parameters:

aTraceOn - if true then all log messages are recorded for this instance. If false, then only the informative, warning and error log messages are recorded.

isTraceOn

public boolean isTraceOn()

Deprecated. This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Returns true if tracing is enabled for this class.

Overrides:

isTraceOn in class ALcdTileDecoder

Returns:

true if tracing is enabled for this class, false otherwise.

readTileFromStream

public ILcdTileInfo readTileFromStream(InputStream aInputStream,
                                       int aImageIndex,
                                       int aSubTileWidth,
                                       int aSubTileHeight,
                                       int aSubTileRowIndex,
                                       int aSubTileColumnIndex,
                                       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.

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

aSubTileColumnIndex - 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.

readTileFromStream

protected ILcdTileInfo readTileFromStream(com.sun.media.jai.codec.SeekableStream aStream,
                                          int aImageIndex,
                                          int aSubTileWidth,
                                          int aSubTileHeight,
                                          int aRowIndex,
                                          int aColumnIndex,
                                          ILcdBuffer aBuffer)
                                   throws TLcdCodecException

Reads a sub-tile from a seekable stream.

Throws:

TLcdCodecException
