Method Details

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

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)

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

populateGlobalMetaData

private void populateGlobalMetaData()
                             throws FormatException,
UnsupportedEncodingException

This function is used to populate values not contained in Core Meta Data to the Global Meta Data

Throws:

FormatException

UnsupportedEncodingException

populateRoiMetaData

private void populateRoiMetaData(MetadataStore store)
                          throws FormatException

Reads and populates ROI Meta Data values. Upto 10 rectangular ROI's may be supported

Throws:

FormatException
