Constructor Detail

VarianFDFReader

public VarianFDFReader()

Constructs a new Varian FDF reader.

Method Detail

isThisType

public boolean isThisType(loci.common.RandomAccessInputStream stream)
                   throws java.io.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:

java.io.IOException

getSeriesUsedFiles

public java.lang.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

See Also:

IFormatReader.getSeriesUsedFiles(boolean)

openBytes

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

java.io.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 java.io.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:

java.io.IOException

initFile

protected void initFile(java.lang.String id)
                 throws FormatException,
                        java.io.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.

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

parseFDF

private void parseFDF(java.lang.String file)
               throws FormatException,
                      java.io.IOException

Throws:

FormatException

java.io.IOException

parseArray

private java.lang.String[] parseArray(java.lang.String value)

Split a String that represents an array into individual elements.

computePhysicalSize

private double computePhysicalSize(int length,
                                   java.lang.String physicalLength,
                                   java.lang.String unit)

Return the physical size of a pixel, in microns, along an arbitrary axis based on the supplied physical and pixel lengths of the axis.

Parameters:

length - the length, in pixels, of the axis

physicalLength - the length, in physical units of the axis

unit - the units for the physical length

Returns:

the size, in microns, of a pixel
