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.
