Field Details

img

private transient BufferedImage img

Transient reference to a BufferedImage for this FormatHandler.currentId. May be null after de-serialization, in which case initImage() must be called.

Constructor Details

ImageIOReader

public ImageIOReader(String name,
 String suffix)

Constructs a new ImageIOReader.

ImageIOReader

public ImageIOReader(String name,
 String[] suffixes)

Constructs a new ImageIOReader.

Method Details

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 FormatReader

Throws:

IOException

getOptimalTileHeight

public int getOptimalTileHeight()

Description copied from interface: IFormatReader

Returns the optimal sub-image height for use with openBytes.

Specified by:

getOptimalTileHeight in interface IFormatReader

Overrides:

getOptimalTileHeight in class FormatReader

openPlane

public Object openPlane(int no,
 int x,
 int y,
 int w,
 int h)
                 throws FormatException,
IOException

Description copied from interface: IFormatReader

Obtains the specified image plane (or sub-image thereof) in the reader's native data structure. For most readers this is a byte array; however, some readers call external APIs that work with other types such as BufferedImage. The openPlane method exists to maintain generality and efficiency while avoiding pollution of the API with AWT-specific logic.

Specified by:

openPlane in interface IFormatReader

Overrides:

openPlane in class FormatReader

Throws:

FormatException

IOException

See Also:

• FormatReader
• BufferedImageReader

initFile

protected void initFile(String id)
                 throws FormatException,
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.

IOException - if an I/O error occurs processing the file

initImage

protected void initImage()
                  throws IOException,
FormatException

Throws:

IOException

FormatException
