Constructor Detail

TrestleReader

public TrestleReader()

Constructs a new Trestle reader.

Method Detail

isThisType

public boolean isThisType(java.lang.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

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

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 MinimalTiffReader

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

fileGroupOption

public int fileGroupOption(java.lang.String id)
                    throws FormatException,
                           java.io.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

java.io.IOException

See Also:

FormatTools.MUST_GROUP, FormatTools.CAN_GROUP, FormatTools.CANNOT_GROUP

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

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

Overrides:

openBytes in class MinimalTiffReader

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 MinimalTiffReader

Throws:

java.io.IOException

getOptimalTileWidth

public int getOptimalTileWidth()

Description copied from interface: IFormatReader

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

Specified by:

getOptimalTileWidth in interface IFormatReader

Overrides:

getOptimalTileWidth in class MinimalTiffReader

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 MinimalTiffReader

initFile

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

Description copied from class: SubResolutionFormatReader

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 BaseTiffReader

Throws:

FormatException - if a parsing error occurs processing the file.

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

initStandardMetadata

protected void initStandardMetadata()
                             throws FormatException,
                                    java.io.IOException

Description copied from class: BaseTiffReader

Parses standard metadata. NOTE: Absolutely no calls to the metadata store should be made in this method or methods that override this method. Data will be overwritten if you do so.

Overrides:

initStandardMetadata in class BaseTiffReader

Throws:

FormatException

java.io.IOException

initMetadataStore

protected void initMetadataStore()
                          throws FormatException

Description copied from class: BaseTiffReader

Populates the metadata store using the data parsed in BaseTiffReader.initStandardMetadata() along with some further parsing done in the method itself. All calls to the active MetadataStore should be made in this method and only in this method. This is especially important for sub-classes that override the getters for pixel set array size, etc.

Overrides:

initMetadataStore in class BaseTiffReader

Throws:

FormatException

parseROIs

private void parseROIs(MetadataStore store)
                throws FormatException,
                       java.io.IOException

Throws:

FormatException

java.io.IOException
