public class OGDIIndexColorModel
extends IndexColorModel
The IndexColorModel class extends an indexed color table with labels for each. There is also the quantity of that category in the geographic object (if matrix).

Version:
1.0
Author:
Las Inc.

Constructor Index

o OGDIIndexColorModel(int, int, byte[], byte[], byte[], byte[], String[], int[])
Creates an OGDIIndexColorModel table with 4 color channels.
o OGDIIndexColorModel(int, int, byte[], int, boolean, int, String[], int[])
Creates an OGDIIndexColorModel instance with a colormap table.

Method Index

o getLabel(int)
Gets a label describing that category.
o getLabels()
Gets a label table for all categories.
o getQuantities()
Gets a quantity of pixels table for all categories.
o getQuantity(int)
Gets a quantity of pixels for that category.
o toString()
Gets the complete color model description.

Constructors

o OGDIIndexColorModel 
 public OGDIIndexColorModel(int bits,
                            int size,
                            byte colorMap[],
                            int start,
                            boolean hasalpha,
                            int trans,
                            String label[],
                            int qty[])
Creates an OGDIIndexColorModel instance with a colormap table. Note: java.awt.image.IndexColorModel does not enforce exception throwing. It's your responsibility to catch ArrayIndexOutOfBoundsException & NullPointerException.

Parameters:
bits - number of bits in each pixel
size - of the palette
colorMap - array of packed red, green, blue and transparency values
start - index of the first value
hasalpha - true if colorMap includes tranparencies
trans - index of the transparent color
label - array of labels
qty - array of quantities of that category in a matrix
Returns:
no return
Throws: IllegalArgumentException
if size less than 1, qty, label out of bounds or contains null

                            String label[],
                            int qty[])
Creates an OGDIIndexColorModel table with 4 color channels. Note: java.awt.image.IndexColorModel does not enforce exception throwing. It's your responsibility to catch ArrayIndexOutOfBoundsException & NullPointerException.

Parameters:

blue - array of blue values
trans - array of transparency values (0 is transparent)
label - array of labels
qty - array of quantities of that category in a matrix
Returns:
no return
Throws: IllegalArgumentException
if size less than 1, qty, label out of bounds or contains null
