*
* <p>
* Old-style JPEG compression as described in section 22 of the TIFF 6.0
* Specification is <i>not</i> supported.
* </p>
*
* <p> The CCITT compression types are applicable to bilevel (1-bit)
* images only. The JPEG compression type is applicable to byte
* grayscale (1-band) and RGB (3-band) images only.</p>
*
* <p>
* ZLib and Deflate compression are identical except for the value of the
* TIFF Compression field: for ZLib the Compression field has value 8
* whereas for Deflate it has value 32946 (0x80b2). In both cases each
* image segment (strip or tile) is written as a single complete zlib data
* stream.
* </p>
*
* <p>
* "Exif JPEG" is a compression type used when writing the contents of an
* APP1 Exif marker segment for inclusion in a JPEG native image metadata
* tree. The contents appended to the output when this compression type is
* used are a function of whether an empty or non-empty image is written.
* If the image is empty, then a TIFF IFD adhering to the specification of
* a compressed Exif primary IFD is appended. If the image is non-empty,
* then a complete IFD and image adhering to the specification of a
* compressed Exif thumbnail IFD and image are appended. Note that the
* data of the empty image may <i>not</i> later be appended using the pixel
* replacement capability of the TIFF writer.
* </p>
*
* <p> If ZLib/Deflate or JPEG compression is used, the compression quality
* may be set. For ZLib/Deflate the supplied floating point quality value is
* rescaled to the range <tt>[1,&nbsp;9]</tt> and truncated to an integer
* to derive the Deflate compression level. For JPEG the floating point
* quality value is passed directly to the JPEG writer plug-in which
* interprets it in the usual way.</p>
*
* <p> The {@code canWriteTiles} and
* {@code canWriteCompressed} methods will return
* {@code true}; the {@code canOffsetTiles} and
* {@code canWriteProgressive} methods will return
* {@code false}.</p>
*
* <p> If tiles are being written, then each of their dimensions will be
* rounded to the nearest multiple of 16 per the TIFF specification. If
* JPEG-in-TIFF compression is being used, and tiles are being written
* each tile dimension will be rounded to the nearest multiple of 8 times
* the JPEG minimum coded unit (MCU) in that dimension. If JPEG-in-TIFF
* compression is being used and strips are being written, the number of
* rows per strip is rounded to a multiple of 8 times the maximum MCU over
* both dimensions.</p>
