javax.imageio.stream.ImageOutputStream

A seekable output stream interface for use by ImageWriters. Various output destinations, such as OutputStreams and Files, as well as future fast I/O destinations may be "wrapped" by a suitable implementation of this interface for use by the Image I/O API.

Unlike a standard OutputStream, ImageOutputStream extends its counterpart, ImageInputStream. Thus it is possible to read from the stream as it is being written. The same seek and flush positions apply to both reading and writing, although the semantics for dealing with a non-zero bit offset before a byte-aligned write are necessarily different from the semantics for dealing with a non-zero bit offset before a byte-aligned read. When reading bytes, any bit offset is set to 0 before the read; when writing bytes, a non-zero bit offset causes the remaining bits in the byte to be written as 0s. The byte-aligned write then starts at the next byte position.

(write this b)
(write this b off len)

Writes a sequence of bytes to the stream at the current position. If len is 0, nothing is written. The byte b[off] is written first, then the byte b[off 1], and so on.

If the bit offset within the stream is non-zero, the remainder of the current byte is padded with 0s and written out first. The bit offset will be 0 after the write. Implementers can use the flushBits method of ImageOutputStreamImpl to guarantee this.

b - an array of bytes to be written. - byte[] off - the start offset in the data. - int len - the number of bytes to write. - int

throws: java.lang.IndexOutOfBoundsException - if off is negative, len is negative, or off len is greater than b.length.

Writes a single bit, given by the least significant bit of the argument, to the stream at the current bit offset within the current byte position. The upper 31 bits of the argument are ignored. The given bit replaces the previous bit at that position. The bit offset is advanced by one and reduced modulo 8.

If any bits of a particular byte have never been set at the time the byte is flushed to the destination, those bits will be set to 0 automatically.

Writes a sequence of bits, given by the numBits least significant bits of the bits argument in left-to-right order, to the stream at the current bit offset within the current byte position.

Note that a bit offset of 0 always indicates the most-significant bit of the byte, and bytes of bits are written out in sequence as they are encountered. Thus bit writes are always effectively in network byte order. The actual stream byte order setting is ignored.

Bit data may be accumulated in memory indefinitely, until flushBefore is called. At that time, all bit data prior to the flushed position will be written.

If any bits of a particular byte have never been set at the time the byte is flushed to the destination, those bits will be set to 0 automatically.

If a character c is in the range \u0800 through uffff, then it is represented by three bytes, to be written in the order shown:

(byte)(0xe0 | (0x0f & (c >> 12))) (byte)(0x80 | (0x3f & (c >> 6))) (byte)(0x80 | (0x3f & c))

First, the total number of bytes needed to represent all the characters of s is calculated. If this number is larger than 65535, then a UTFDataFormatException is thrown. Otherwise, this length is written to the output stream in exactly the manner of the writeShort method; after this, the one-, two-, or three-byte representation of each character in the string s is written.

The current byte order setting is ignored.

If the bit offset within the stream is non-zero, the remainder of the current byte is padded with 0s and written out first. The bit offset will be 0 after the write.

Note: This method should not be used in the implementation of image formats that use standard UTF-8, because the modified UTF-8 used here is incompatible with standard UTF-8.

s - a String containing the value to be written. - java.lang.String

throws: java.lang.NullPointerException - if s is null.

Writes two bytes of length information to the output stream in
 network byte order, followed by the
 modified
 UTF-8
 representation of every character in the string s.
 If s is null, a
 NullPointerException is thrown.  Each character in
 the string s is converted to a group of one, two,
 or three bytes, depending on the value of the character.

  If a character c is in the range
 \u0001 through \u007f, it is
 represented by one byte:



 (byte)c

  If a character c is \u0000 or
 is in the range \u0080 through
 \u07ff, then it is represented by two bytes,
 to be written in the order shown:



 (byte)(0xc0 | (0x1f & (c >> 6)))
 (byte)(0x80 | (0x3f & c))

  If a character c is in the range
 \u0800 through uffff, then it is
 represented by three bytes, to be written in the order shown:



 (byte)(0xe0 | (0x0f & (c >> 12)))
 (byte)(0x80 | (0x3f & (c >> 6)))
 (byte)(0x80 | (0x3f & c))

  First, the total number of bytes needed to represent all
 the characters of s is calculated. If this number
 is larger than 65535, then a
 UTFDataFormatException is thrown. Otherwise, this
 length is written to the output stream in exactly the manner of
 the writeShort method; after this, the one-, two-,

 s is written.

 because  the modified UTF-8 used here is incompatible with
 standard UTF-8.
