public interface ImageOutputStream
extends ImageInputStream sample code for javax.imageio.stream.ImageInputStream definition code for javax.imageio.stream.ImageInputStream , DataOutput sample code for java.io.DataOutput definition code for java.io.DataOutput

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.

Parameters:
s - a String containing the value to be written.

writeChars sample code for javax.imageio.stream.ImageOutputStream.writeChars(java.lang.String) definition code for javax.imageio.stream.ImageOutputStream.writeChars(java.lang.String) 

void writeChars(String sample code for java.lang.String definition code for java.lang.String  s)
                throws IOException sample code for java.io.IOException definition code for java.io.IOException
Writes a string to the output stream. For every character in the string s, taken in order, two bytes are written to the output stream, ordered according to the current byte order setting. If network byte order is being used, the high-order byte is written first; the order is reversed otherwise. If s is null, a NullPointerException is thrown.

If s.length is zero, then no bytes are written. Otherwise, the character s[0] is written first, then s[1], and so on; the last character written is s[s.length-1].

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.

Parameters:

writeUTF sample code for javax.imageio.stream.ImageOutputStream.writeUTF(java.lang.String) definition code for javax.imageio.stream.ImageOutputStream.writeUTF(java.lang.String) 

void writeUTF(String sample code for java.lang.String definition code for java.lang.String  s)
              throws IOException sample code for java.io.IOException definition code for java.io.IOException
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-, 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.

writeBit sample code for javax.imageio.stream.ImageOutputStream.writeBit(int) definition code for javax.imageio.stream.ImageOutputStream.writeBit(int) 

void writeBit(int bit)
              throws IOException sample code for java.io.IOException definition code for java.io.IOException
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.

Parameters:
bit - an int whose least significant bit is to be written to the stream.
Throws:
IOException sample code for java.io.IOException definition code for java.io.IOException - if an I/O error occurs.

writeBits sample code for javax.imageio.stream.ImageOutputStream.writeBits(long, int) definition code for javax.imageio.stream.ImageOutputStream.writeBits(long, int) 

void writeBits(long bits,
               int numBits)
               throws IOException sample code for java.io.IOException definition code for java.io.IOException
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. The upper 64 - numBits bits of the argument are ignored. The bit offset is advanced by numBits and reduced modulo 8. 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.

Parameters:
bits - a long containing the bits to be written, starting with the bit in position numBits - 1 down to the least significant bit.
numBits - an int between 0 and 64, inclusive.
Throws:
IllegalArgumentException sample code for java.lang.IllegalArgumentException definition code for java.lang.IllegalArgumentException - if numBits is not between 0 and 64, inclusive.
IOException sample code for java.io.IOException definition code for java.io.IOException - if an I/O error occurs.
