JP2KFormat
public final class JP2KFormat
An implementation of Format
for the JP2K format.
Field Summary | |
---|---|
static ParameterDescriptor<Color> |
INPUT_TRANSPARENT_COLOR
Control the transparency of the input coverages. |
static DefaultParameterDescriptor<String> |
SUGGESTED_TILE_SIZE
This GeneralParameterValue can be provided to the
GridCoverageReader s through the
GridCoverageReader.read(GeneralParameterValue[]) method in order
to specify the suggested size of tiles to avoid long time reading
occurring with JAI ImageRead on striped images. |
static String |
TILE_SIZE_SEPARATOR
|
static DefaultParameterDescriptor<Boolean> |
USE_MULTITHREADING
This GeneralParameterValue can be provided to the
GridCoverageReader s through the
GridCoverageReader.read(GeneralParameterValue[]) method in order
to specify to use multithreading when leveraging on a JAI ImageRead
operation. |

boolean |
accepts(Object input)
Tells me if this Format can read the provided input . |
GeoToolsWriteParams |
getDefaultImageIOWriteParameters()
Returns an instance of ImageWriteParam that can be used to
control a subsequent

public static final DefaultParameterDescriptor<Boolean> USE_MULTITHREADING
GeneralParameterValue
can be provided to the
GridCoverageReader
s through the
GridCoverageReader.read(GeneralParameterValue[])
method in order
to specify to use multithreading when leveraging on a JAI ImageRead
operation. This will be achieved with the use of the ImageReadMT
operation of the ImageIO-Ext.
public static final DefaultParameterDescriptor<String> SUGGESTED_TILE_SIZE
GeneralParameterValue
can be provided to the
GridCoverageReader
s through the
GridCoverageReader.read(GeneralParameterValue[])
method in order
to specify the suggested size of tiles to avoid long time reading
occurring with JAI ImageRead on striped images. (Images with tiles Nx1)
Value should be a String in the form of "W,H" (without quotes) where W is
a number representing the suggested tileWidth and H is a number
representing the suggested tileHeight.
