| * <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, 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> |
