Constructor Details

ZeissTIFFReader

public ZeissTIFFReader()

Method Details

isSingleFile

public boolean isSingleFile(String id)
                     throws FormatException,
IOException

Description copied from interface: IFormatReader

Returns true if the named file is expected to be the only file in the dataset. For single-file formats, always returns true.

Specified by:

isSingleFile in interface IFormatReader

Overrides:

isSingleFile in class FormatReader

Throws:

FormatException

IOException

getPrefix

protected String getPrefix(String name)

isThisType

public boolean isThisType(String name,
 boolean open)

Description copied from class: FormatReader

Checks if a file matches the type of this format reader. Checks filename suffixes against those known for this format. If the suffix check is inconclusive and the open parameter is true, the file is opened and tested with FormatReader.isThisType(RandomAccessInputStream).

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType in class FormatReader

Parameters:

open - If true, and the file extension is insufficient to determine the file type, the (existing) file is opened for further analysis.

fileGroupOption

public int fileGroupOption(String id)
                    throws FormatException,
IOException

Description copied from interface: IFormatReader

Returns an indication of whether the files in a multi-file dataset can be handled individually. This method is only useful for formats and datasets which contain multiple files.

Specified by:

fileGroupOption in interface IFormatReader

Overrides:

fileGroupOption in class FormatReader

Parameters:

id - a file in the multi-file dataset

Returns:

an int indicating that we cannot, must, or might group the files. A return value of FormatTools.MUST_GROUP indicates that the files cannot be handled separately; the reader will always detect and read all files in the dataset. FormatTools.CAN_GROUP indicates that the files may be handled separately, but file grouping must then be disabled via IFormatReader.setGroupFiles(boolean). FormatTools.CANNOT_GROUP indicates that the files must be handled separately; the reader will not attempt to read all files in the dataset (this is rare).

Throws:

FormatException

IOException

See Also:

• FormatTools.MUST_GROUP
• FormatTools.CAN_GROUP
• FormatTools.CANNOT_GROUP

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 BaseZeissReader

Throws:

IOException

evalFile

protected ZeissTIFFReader.TIFFInfo evalFile(String id)
                                     throws FormatException,
IOException

Evaluate the metadata of a TIFF/XML file collection, and return this to the user. This is done by filling a TIFFInfo object containing all of the file and directory paths, plus the parsed metadata.

Parameters:

id - the filename to evaluate. This may be the top-level or per-plane TIFF, or the XML metadata.

Returns:

an TIFFInfo object.

Throws:

FormatException

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

initVars

protected void initVars(String id)
                 throws FormatException,
IOException

Overrides:

initVars in class BaseZeissReader

Throws:

FormatException

IOException

fillMetadataPass1

protected void fillMetadataPass1(MetadataStore store)
                          throws FormatException,
IOException

Description copied from class: BaseZeissReader

Read and store basic dimensions in model

Overrides:

fillMetadataPass1 in class BaseZeissReader

Parameters:

store -

Throws:

FormatException

IOException

fillMetadataPass2

protected void fillMetadataPass2(MetadataStore store)
                          throws FormatException,
IOException

Description copied from class: BaseZeissReader

Read and store basic dimensions in model

Overrides:

fillMetadataPass2 in class BaseZeissReader

Parameters:

store -

Throws:

FormatException

IOException

fillMetadataPass5

protected void fillMetadataPass5(MetadataStore store)
                          throws FormatException,
IOException

Description copied from class: BaseZeissReader

Read and store basic dimensions in model

Overrides:

fillMetadataPass5 in class BaseZeissReader

Parameters:

store -

Throws:

FormatException

IOException

countImages

protected void countImages()

Overrides:

countImages in class BaseZeissReader

lookup

private String lookup(String src)

Translate a file path from the XML file to an actual path on disk. The path stored in the XML file may not have the same case as the path on disk (typically all lower case on disk and possibly mixed case in XML). If a matching file cannot be found, then the path from the XML file is returned. Uses directoryCache so that any given directory is only listed once per initialization, not once per lookup.
