public interface ILcdTileDecoder

This interface contains methods to decode a sub-tile from a whole tile (image) contained in a file or URL.

Method Summary

Modifier and Type	Method and Description
ILcdTileInfo	readTile(String aFileName, int aImageIndex, int aSubTileWidth, int aSubTileHeight, int aSubTileRowIndex, int aSubTileColumnIndex, ILcdBuffer aBuffer) Reads a sub-tile from a file.
ILcdTileInfo	readTile(URL aURL, int aImageIndex, int aSubTileWidth, int aSubTileHeight, int aSubTileRowIndex, int aSubTileColumnIndex, ILcdBuffer aBuffer) Reads a sub-tile from a URL.

Method Detail

readTile

ILcdTileInfo readTile(String aFileName,
                      int aImageIndex,
                      int aSubTileWidth,
                      int aSubTileHeight,
                      int aSubTileRowIndex,
                      int aSubTileColumnIndex,
                      ILcdBuffer aBuffer)
               throws TLcdCodecException

Reads a sub-tile from a file.

Parameters:

aFileName - the name of the file containing the tile.

aImageIndex - the index of the tile in the given file (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.

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.
