public class FileImageInputStream extends ImageInputStreamImpl
ImageInputStream that gets its
input from a File or RandomAccessFile.
The file contents are assumed to be stable during the lifetime of
the object.bitOffset, byteOrder, flushedPos, streamPos| Constructor | Description |

FileImageInputStream(File f) |
Constructs a
FileImageInputStream that will read
from a given File. |
FileImageInputStream(RandomAccessFile raf) |
Constructs a
FileImageInputStream that will read
from a given RandomAccessFile. |

|---|---|---|
void |
close() |
Closes the stream.
|
protected void |
finalize() |
Finalizes this object prior to garbage collection.
|
long |
length() |
Returns the length of the underlying file, or
-1
if it is unknown. |
int |
read() |
Reads a single byte from the stream and returns it as an
int between 0 and 255. |
int |
read(byte[] b,
int off,

Reads up to
len bytes from the stream, and stores
them into b starting at index off. |
void |
seek(long pos) |
