    • 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 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:
      IOException
    • 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
      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.
      IOException - if there was a problem reading the file.
      See Also:
    • 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 MinimalTiffReader
      Throws:
      IOException
    • initFile

      protected void initFile(String id) throws FormatException, 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.
      IOException - if an I/O error occurs processing the file
    • openPixelTag

      private void openPixelTag() throws IOException
      Throws:
      IOException
