Constructor Details

FileMetaImage

public FileMetaImage(String fName,
 String fDir)

Constructs new file object.

Parameters:

fName - File name.

fDir - File directory.

Method Details

readImage

public ModelImage readImage(boolean one)
                     throws IOException

reads the MetaImatge file header and data.

Parameters:

one - DOCUMENT ME!

Returns:

DOCUMENT ME!

Throws:

IOException - if there is an error reading the file

updateorigins

private void updateorigins(FileInfoBase[] fileInfo)

Updates the start locations. Each image has a fileinfo where the start locations are stored. Note that the start location for the Z (3rd) dimension change with the change is the slice. The origin is in the upper left corner and we are using the right hand rule. + x -> left to right; + y -> top to bottom and + z -> into screen.

Parameters:

fileInfo - DOCUMENT ME!

readLine

private void readLine()
               throws IOException

readLine() - reads a line of the file header separate into category, subcategory, and values.

Throws:

IOException - if there is an error reading the file

writeImage

public void writeImage(ModelImage image,
 FileWriteOptions options)
                throws IOException

Writes an MetaImage format type image.

Parameters:

image - Image model of data to write.

Throws:

IOException - if there is an error writing the file

• invalid reference

  FileInfoMeta

• FileRaw

writeHeader

public boolean writeHeader(ModelImage image,
 int nImagesSaved,
 int nTimeSaved,
 String fileName,
 String fileDir,
 boolean oneFile,
 int headerIndex,
 long[] finalHeaderPosition)
                    throws IOException

Writes a MetaImage header to a separate file.

Parameters:

image - Image model of data to write.

fileName - File name.

fileDir - File directory.

Returns:

Flag to confirm a successful read.

Throws:

IOException - if there is an error

• FileInfoMetaImage

writeHeader3DTo2D

private void writeHeader3DTo2D(ModelImage image,
 String fileName,
 String fileDir,
 FileWriteOptions options,
 boolean oneFile,
 long[] finalHeaderPosition)
                        throws IOException

This method is used when saving a 3D image in an array of 2D files. The file name has numbers appended to correctly order the images.

Parameters:

image - the image dataset to be saved

fileName - the file name

fileDir - the file directory

options - file options indicate how to save the image

Throws:

IOException - DOCUMENT ME!

writeHeader4DTo3D

 String fileName,
 String fileDir,
 FileWriteOptions options,
 boolean oneFile,
 long[] finalHeaderPosition)
                        throws IOException

This method is used when saving a 4D image in an array of 3D files. The file name has numbers appended to correctly order the images.

Parameters:

image - the image dataset to be saved

fileName - the file name

fileDir - the file directory

options - file options indicate how to save the image

Throws:
