public class TIFFImageReadParam extends ImageReadParam
Because TIFF is an extensible format, the reader requires information about any tags used by TIFF extensions in order to emit meaningful metadata. Also, TIFF extensions may define new compression types. Both types of information about extensions may be provided by this interface.
Additional TIFF tags must be organized into
TIFFTagSet
s. A TIFFTagSet
may be
provided to the reader by means of the
addAllowedTagSet
method. By default, the tag sets
BaselineTIFFTagSet
, FaxTIFFTagSet
,
EXIFParentTIFFTagSet
, and GeoTIFFTagSet
are included.
New TIFF decompressors are handled in a simple fashion. If a
non-null
TIFFDecompressor
is provided by
means of the setTIFFDecompressor method, it will override the
reader's usual choice of decompressor. Thus, to read an image with
a non-standard compression type, the application should first
attempt to read the image's metadata and extract the compression
type. The application may then use its own logic to choose a
suitable TIFFDecompressor
, instantiate it, and pass it
to the ImageReadParam
being used. The reader's
read
method may be called with the
ImageReadParam
set.

TIFFImageReadParam()
Constructs a TIFFImageReadParam . |
Method Summary | |
---|---|
void | addAllowedTagSet(TIFFTagSet tagSet)
Adds a TIFFTagSet object to the list of allowed
tag sets.
|
List | getAllowedTagSets()
Returns a List containing the allowed
TIFFTagSet objects.
|
TIFFColorConverter | getColorConverter()
Returns the currently set TIFFColorConverter object,
or null if none is set.
|
TIFFDecompressor | getTIFFDecompressor()
Returns the TIFFDecompressor that is currently set
to be used by the ImageReader to decode each image
strip or tile, or null if none has been set.
|
void | removeAllowedTagSet(TIFFTagSet tagSet)
Removes a TIFFTagSet object from the list of
allowed tag sets. |
void | setColorConverter(TIFFColorConverter colorConverter)
Sets the TIFFColorConverter object for the pixel data
being read. |
void | setTIFFDecompressor(TIFFDecompressor decompressor)
Sets the TIFFDecompressor object to be used by the
ImageReader to decode each image strip or tile.

TIFFImageReadParam
. Tags defined by
the TIFFTagSet
s BaselineTIFFTagSet
,
FaxTIFFTagSet
, EXIFParentTIFFTagSet
, and
GeoTIFFTagSet
will be supported.

TIFFTagSet
object to the list of allowed
tag sets.
Parameters: tagSet a TIFFTagSet
.
Throws: IllegalArgumentException if tagSet
is
null
.
List
containing the allowed
TIFFTagSet
objects.
Returns: a List
of TIFFTagSet
s.
TIFFColorConverter
object,
or null
if none is set.
Returns: the current TIFFColorConverter
object.
See Also: setColorConverter
TIFFDecompressor
that is currently set
to be used by the ImageReader
to decode each image
strip or tile, or null
if none has been set.
Returns: decompressor the TIFFDecompressor
to be
used for decoding, or null
if none has been set
(allowing the reader to choose its own).
See Also: setTIFFDecompressor
TIFFTagSet
object from the list of
allowed tag sets. Removal is based on the equals
method of the TIFFTagSet
, which is normally
defined as reference equality.
Parameters: tagSet a TIFFTagSet
.
Throws: IllegalArgumentException if tagSet
is
null
.
TIFFColorConverter
object for the pixel data
being read. The data will be converted from the given color
space to a standard RGB space as it is being read. A value of
null
disables conversion.
Parameters: colorConverter a TIFFColorConverter
object
to be used for final color conversion, or null
.
See Also: TIFFImageReadParam
TIFFDecompressor
object to be used by the
ImageReader
to decode each image strip or tile.
A value of null
allows the reader to choose its
own TIFFDecompressor.
Parameters: decompressor the TIFFDecompressor
to be
used for decoding, or null
to allow the reader to
choose its own.
