Method Detail

getFileVersion

private int getFileVersion(loci.common.RandomAccessInputStream stream)
                    throws IOException

Throws:

IOException

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.

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType 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

initStack

private long initStack(long current,
                       int fileVersion)
                throws FormatException,
                       IOException

Throws:

FormatException

IOException

getPixelType

private int getPixelType(int type)
                  throws FormatException

Throws:

FormatException

getBitsPerPixel

private int getBitsPerPixel(int type)
                     throws FormatException

Throws:

FormatException

getLength

private long getLength(long length)
                throws FormatException

Throws:

FormatException

getCompression

private boolean getCompression(int compression)
                        throws FormatException

Throws:

FormatException

readString

private String readString()
                   throws IOException

Throws:

IOException

openBytes

public byte[] openBytes(int no,
                        byte[] buffer,
                        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.

buffer - 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.

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

getChildNodes

private ArrayList<Element> getChildNodes(Element root)
