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. 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:

IOException

                            throws FormatException,
IOException

Description copied from interface: IFormatReader

Gets the 8-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null. Also, if IFormatReader.getPixelType() returns anything other than FormatTools.INT8 or FormatTools.UINT8, this method will return null.

Specified by:

Description copied from interface: IFormatReader

Gets the 16-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null.

Specified by:

get16BitLookupTable in interface IFormatReader

Overrides:
