public class NativeND2Reader
extends FormatReader

NativeND2Reader is the file format reader for Nikon ND2 files. The JAI ImageIO library is required to use this reader; it is available from http://jai-imageio.dev.java.net. Note that JAI ImageIO is bundled with a version of the JJ2000 library, so it is important that either: (1) the JJ2000 jar file is *not* in the classpath; or (2) the JAI jar file precedes JJ2000 in the classpath. Thanks to Tom Caswell for additions to the ND2 metadata parsing logic.

Constructs a new ND2 reader.

Method Detail

isThisType

public boolean isThisType(RandomAccessInputStream stream)
                   throws IOException

Description copied from interface: IFormatReader

Checks if the given stream is a valid stream for this file format.

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType in class FormatReader

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 image index within the file.

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)

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 FormatReader

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

iterateIn

private void iterateIn(RandomAccessInputStream in,

Function for iterating through ND2 metaAttributes

Parameters:

in - stream of bytes from file

stop - position where to stop
