| Field Summary | |
| final static boolean | USE_JAI_MODEL
Tells if we should use
ComponentSampleModelJAI instead of the more standard
ComponentSampleModel . | | final protected float | maximum
The maximal value, inclusive. | | final protected float | minimum
The minimal value, inclusive. |
| Constructor Summary | |
| protected | ContinuousPalette(PaletteFactory factory, String name, float minimum, float maximum, int dataType, int numBands, int visibleBand)
Creates a palette with the specified name. |
| Method Summary | |
| public boolean | equals(Object object)
Compares this palette with the specified object for equality. | | public synchronized ImageTypeSpecifier | getImageTypeSpecifier()
Creates a grayscale image type for this palette. | | double | getOffset()
Returns the offset from normalized values (values in the range [0..1])
to values in the range of this palette. | | double | getScale()
Returns the scale from normalized values (values in the range [0..1])
to values in the range of this palette. | | public int | hashCode()
Returns a hash value for this palette. | | public String | toString()
Returns a string representation of this palette. |
| USE_JAI_MODEL | | final static boolean USE_JAI_MODEL(Code) | | Tells if we should use
ComponentSampleModelJAI instead of the more standard
ComponentSampleModel . There is two problems with models provided with J2SE 1.4:
This flag is set to
true for J2SE 1.4. It may be
changed to
false with future J2SE and JAI versions.
|
| maximum | | final protected float maximum(Code) | | The maximal value, inclusive.
|
| minimum | | final protected float minimum(Code) | | The minimal value, inclusive.
|
| ContinuousPalette | | protected ContinuousPalette(PaletteFactory factory, String name, float minimum, float maximum, int dataType, int numBands, int visibleBand)(Code) | | Creates a palette with the specified name.
Parameters:
factory - The originating factory.
Parameters:
name - The palette name.
Parameters:
minimum - The minimal sample value expected.
Parameters:
maximum - The maximal sample value expected.
Parameters:
dataType - The data type as a DataBuffer.TYPE_FLOATor DataBuffer.TYPE_DOUBLE constant.
Parameters:
numBands - The number of bands (usually 1).
Parameters:
visibleBand - The band to use for color computations (usually 0). |
| equals | | public boolean equals(Object object)(Code) | | Compares this palette with the specified object for equality.
|
| getImageTypeSpecifier | | public synchronized ImageTypeSpecifier getImageTypeSpecifier() throws IOException(Code) | | Creates a grayscale image type for this palette.
The image type is suitable for floating point values.
A default color space scaled to fit data.
throws:
IOException - If an I/O operation was needed and failed. |
| getOffset | | double getOffset()(Code) | | Returns the offset from normalized values (values in the range [0..1])
to values in the range of this palette.
|
| getScale | | double getScale()(Code) | | Returns the scale from normalized values (values in the range [0..1])
to values in the range of this palette.
|
| hashCode | | public int hashCode()(Code) | | Returns a hash value for this palette.
|
| toString | | public String toString()(Code) | | Returns a string representation of this palette. Used for debugging purpose only.
