- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class TransposeDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor
describing the "Transpose" operation.
The "Transpose" operation performs the following operations:
- Flip an image across an imaginary horizontal line that runs
through the center of the image (FLIP_VERTICAL).
- Flip an image across an imaginary vertical line that runs
through the center of the image (FLIP_HORIZONTAL).
- Flip an image across its main diagonal that runs from the upper
left to the lower right corner (FLIP_DIAGONAL).
- Flip an image across its main antidiagonal that runs from the
upper right to the lower left corner(FLIP_ANTIDIAGONAL).
- Rotate an image clockwise by 90, 180, or 270 degrees
(ROTATE_90, ROTATE_180, ROTATE_270).
In all cases, the resulting image will have the same origin (as
defined by the return values of its getMinX()
and
getMinY()
methods) as the source image.
It should be noted that this operation automatically adds a
value of Boolean.TRUE
for the
JAI.KEY_REPLACE_INDEX_COLOR_MODEL
to the given
configuration
so that the operation is performed
on the pixel values instead of being performed on the indices into
the color map if the source(s) have an IndexColorModel
.
This addition will take place only if a value for the
JAI.KEY_REPLACE_INDEX_COLOR_MODEL
has not already been
provided by the user. Note that the configuration
Map
is cloned before the new hint is added to it. The operation can be
smart about the value of the JAI.KEY_REPLACE_INDEX_COLOR_MODEL
RenderingHints
, i.e. while the default value for the
JAI.KEY_REPLACE_INDEX_COLOR_MODEL
is
Boolean.TRUE
, in some cases the operator could set the
default.
"Transpose" defines a PropertyGenerator that
performs an identical transformation on the "ROI" property of the
source image, which can be retrieved by calling the
getProperty
method with "ROI" as the property name.
