public class FlowSightReader
extends FormatReader

Author:

Lee Kamentsky Reader for the Amris ImageStream / FlowSight file format The cif file format is tiff-like, but doesn't adhere to the TIFF standard, so we use the TiffParser where we can, but do not use the TiffReader hierarchy.

FlowSightReader

public FlowSightReader()

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.

Specified by:

isThisType in interface IFormatReader

Overrides:

isThisType 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

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

reopenFile

public void reopenFile()
                throws java.io.IOException

Description copied from interface: IFormatReader

Reopen any files that were closed, and which are expected to be open while the reader is open. This assumes that IFormatHandler.setId(java.lang.String) has been called, but close(false) has not been called.

Specified by:

reopenFile in interface IFormatReader

Overrides:

reopenFile in class FormatReader

Throws:

java.io.IOException

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 image index within the file.

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.

openBitmaskBytes

private byte[] openBitmaskBytes(IFD ifd,
                                int imageWidth,
                                int imageHeight)
                         throws FormatException

Decode the whole IFD plane using bitmask compression

Parameters:

ifd - - the IFD to decode

imageWidth - the width of the IFD plane

imageHeight - the height of the IFD plane

Returns:

a byte array of length imageWidth * imageHeight containing the uncompressed data

Throws:

                                  int imageWidth,
                                  int imageHeight)
                           throws FormatException
