Method Detail

formatCompression

private void formatCompression(IFD ifd)
                        throws FormatException

Sets the compression code for the specified IFD.

Parameters:

ifd - The IFD table to handle.

Throws:

FormatException

setId

public void setId(String id)
           throws FormatException,
                  IOException

Description copied from class: FormatWriter

Initializes a writer from the input file name. Initializes a RandomAccessOutputStream for the output file and initializes the metadata for all the series using FormatWriter.setSeries(int).

Specified by:

setId in interface IFormatHandler

Overrides:

setId in class FormatWriter

Parameters:

id - a String specifying the path to the file

Throws:

FormatException

IOException

saveBytes

public void saveBytes(int no,
             byte[] buf,
             IFD ifd)
               throws IOException,
                      FormatException

Saves the given image to the specified (possibly already open) file. The IFD hashtable allows specification of TIFF parameters such as bit depth, compression and units.

Throws:

IOException

FormatException

saveBytes

public void saveBytes(int no,
             byte[] buf,
             IFD ifd,
             int x,
             int y,
             int w,
             int h)
               throws IOException,
                      FormatException

Saves the given image to the specified series in the current file. The IFD hashtable allows specification of TIFF parameters such as bit depth, compression and units.

Throws:

IOException

FormatException

prepareToWriteImage

protected int prepareToWriteImage(int no,
                      byte[] buf,
                      IFD ifd,
                      int x,

                                  FormatException

Performs the preparation for work prior to the usage of the TIFF saver. This method is factored out from saveBytes() in an attempt to ensure thread safety.

Throws:

IOException

Description copied from interface: IFormatWriter

Saves the given image tile to the current series in the current file.

Parameters:

no - the image index within the current file, starting from 0.

buf - the byte array that represents the image tile.

y - the Y coordinate of the upper-left corner of the image tile.

w - the width (in pixels) of the image tile.

h - the height (in pixels) of the image tile.

Throws:
