   +----com.las.ogdi.OGDIRasterInfo
public class OGDIRasterInfo
extends Object
The RasterInfo class defines an object with minimum and maximum categories and a table of category-to-color (with labels). Applies to matrix/image only.

Version:
1.1
Author:
Las Inc.

Constructor Index

o OGDIRasterInfo(int, int, int, DirectColorModel)
Creates a RasterInfo instance for Image family.
o OGDIRasterInfo(int, int, OGDIIndexColorModel)
Creates a RasterInfo instance for Matrix family.

Method Index

o getCallback()
Gets the current callback for the value/category transformation.
o getColorModel()
Gets the table of colors (for matrix, where the index is the category).
o getMaxCat()
Gets one maximum color/category for the matrix datasource.
o getMinCat()
Gets one minimum color/category for the matrix datasource.
o getWidth()
Gets the width of the raster (used as the type for Image where 1=RGB, etc).
o setCallback(OGDIRasterCallback)
Sets the current callback for the value/category transformation.
o toString()
Gets the complete rasterInfo description.

Constructors

o OGDIRasterInfo 
 public OGDIRasterInfo(int mincat,
                       int maxcat,
                       OGDIIndexColorModel cat)
Creates a RasterInfo instance for Matrix family. Category 0 represents "no information" (transparent).

Parameters:
mincat - the minimum category for that matrix
maxcat - the maximum category for that matrix
cat - the table of colors
Returns:
no return
Throws: IllegalArgumentException
if minimum or maximum are out of range or categories are null
o OGDIRasterInfo 
 public OGDIRasterInfo(int mincat,
                       int maxcat,
                       int type,
                       DirectColorModel cat)
Creates a RasterInfo instance for Image family.

Parameters:
mincat - the minimum pixel value for that image
maxcat - the maximum pixel value for that image
type - the type of image (1=RGB, 2=8 ubits, 3=16 ubits, 4=16 bits signed, 5=32 bits)
cat - the table of colors
Returns:
no return
Throws: IllegalArgumentException
if minimum or maximum are out of range or colors are null

Methods

o getWidth 
 public int getWidth()
Gets the width of the raster (used as the type for Image where 1=RGB, etc).

Parameters:
no - parameter
Returns:
the width or type of the raster
Throws: no
exception
o getMinCat 
 public int getMinCat()
Gets one minimum color/category for the matrix datasource.

Parameters:
no - parameter
Returns:
the minimum color/category in the color table
Throws: no
exception
o getMaxCat 
 public int getMaxCat()
Gets one maximum color/category for the matrix datasource.

Parameters:
no - parameter
Returns:
the maximum color/category in the color table
Throws: no
exception
o getColorModel 
 public ColorModel getColorModel()
Gets the table of colors (for matrix, where the index is the category).

Parameters:
no - parameter
Returns:
the ColorModel reference
Throws: no
exception
o getCallback 
 public OGDIRasterCallback getCallback()
Gets the current callback for the value/category transformation.

Parameters:
no - parameter
Returns:
the callback object
Throws: no
exception
o setCallback 
 public void setCallback(OGDIRasterCallback callback)
Sets the current callback for the value/category transformation. There is a default implementation for each raster type.

Parameters:
callback - a callback processor of pixel values/categories
Returns:
no return
Throws: no
exception
o toString 
 public String toString()
Gets the complete rasterInfo description.

Parameters:
no - parameter
Returns:
the raster info minimum, maximum and table of categories as a string
Throws: no
exception
Overrides:
toString in class Object
