Constructor Details

LOFReader

public LOFReader()

Constructs a new Leica LOF reader.

LOFReader

public LOFReader(XlifDocument xlif)

Method Details

getOptimalTileHeight

public int getOptimalTileHeight()

Description copied from interface: IFormatReader

Returns the optimal sub-image height for use with openBytes.

Specified by:

getOptimalTileHeight in interface IFormatReader

Overrides:

getOptimalTileHeight in class FormatReader

isThisType

public boolean isThisType(loci.common.RandomAccessInputStream stream)
                   throws IOException

Description copied from interface: IFormatReader

Checks if the given stream is a valid stream for this file format. The number of bytes read is format-dependent.

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType in class FormatReader

Parameters:

stream - A RandomAccessInputStream representing the file to check. The first byte in the stream is assumed to be the first byte in the file.

Returns:

true if the file represented by the stream can be read by this reader; false otherwise.

Throws:

IOException

get8BitLookupTable

public byte[][] get8BitLookupTable()

Description copied from interface: IFormatReader

Gets the 8-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null. Also, if IFormatReader.getPixelType() returns anything other than FormatTools.INT8 or FormatTools.UINT8, this method will return null.

Specified by:

get8BitLookupTable in interface IFormatReader

Overrides:

get8BitLookupTable in class FormatReader

get16BitLookupTable

public short[][] get16BitLookupTable()

Description copied from interface: IFormatReader

Gets the 16-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null. Also, if IFormatReader.getPixelType() returns anything other than FormatTools.INT16 or FormatTools.UINT16, this method will return null.

Specified by:

get16BitLookupTable in interface IFormatReader

Overrides:

get16BitLookupTable in class FormatReader

openBytes

public byte[] openBytes(int no,
 byte[] buf,
 int x,
 int y,
 int w,
 int h)
                 throws FormatException,
IOException

Description copied from interface: IFormatReader

Obtains a sub-image of the specified image plane into a pre-allocated byte array.

Specified by:

openBytes in interface IFormatReader

Specified by:

openBytes in class FormatReader

Parameters:

no - the plane index within the current series.

buf - a pre-allocated buffer.

x - X coordinate of the upper-left corner of the sub-image

y - Y coordinate of the upper-left corner of the sub-image

w - width of the sub-image

h - height of the sub-image

Returns:

the pre-allocated buffer buf for convenience.

Throws:

FormatException - if there was a problem parsing the metadata of the file.

IOException - if there was a problem reading the file.

See Also:

• IFormatReader.openBytes(int, byte[], int, int, int, int)

getSeriesUsedFiles

public String[] getSeriesUsedFiles(boolean noPixels)

Description copied from interface: IFormatReader

Returns an array of filenames needed to open the current series. If the 'noPixels' flag is set, then only files that do not contain pixel data will be returned. The first element in the array is expected to be the path passed to IFormatHandler.setId(String), if appropriate based upon 'noPixels'. The remaining elements are expected to be in a consistent order; if a directory listing is necessary to build the list then it should be sorted first.

Specified by:

getSeriesUsedFiles in interface IFormatReader

Overrides:

getSeriesUsedFiles in class FormatReader

close

public void close(boolean fileOnly)
           throws IOException

Description copied from interface: IFormatReader

Closes the currently open file. If the flag is set, this is all that happens; if unset, it is equivalent to calling Closeable.close().

Specified by:

close in interface IFormatReader

Overrides:

close in class LMSFileReader

Throws:

IOException

initFile

protected void initFile(String id)
                 throws FormatException,
IOException

Description copied from class: FormatReader

Initializes the given file (parsing header information, etc.). Most subclasses should override this method to perform initialization operations such as parsing metadata.

Overrides:

initFile in class FormatReader

Throws:

FormatException - if a parsing error occurs processing the file.

IOException - if an I/O error occurs processing the file

getImageFormat

public LMSFileReader.ImageFormat getImageFormat()

Description copied from class: LMSFileReader

Returns the file format in which actual image bytes are stored

Specified by:

getImageFormat in class LMSFileReader

checkForLofLayout

private void checkForLofLayout(loci.common.RandomAccessInputStream in,
 String filename)
                        throws FormatException,
IOException

Checks if file layout meets lof file specifications

Parameters:

in - lof file stream

filename - name of the lof file

Throws:

FormatException

IOException

seekStartOfPlane

private void seekStartOfPlane(int no,
 long dataOffset,
 long planeSize)
                       throws IOException

Throws:

IOException

getTileIndex

private int getTileIndex(int coreIndex)

setIdWithMetadata

public void setIdWithMetadata(String id,
 XlifDocument xml)
                       throws FormatException,
IOException

Inits the LOFReader using passed xml (from XLIF) for metadata initiation, instead of reading the LOF's included xml

Parameters:

id - LOF file id

xml - XML from xlif that points to LOF file

Throws:

FormatException

IOException
