类 OctTreeQuantizer

java.lang.Object

org.meteoinfo.image.filter.OctTreeQuantizer

所有已实现的接口:

Quantizer

public class OctTreeQuantizer
extends Object
implements Quantizer

An image Quantizer based on the Octree algorithm. This is a very basic implementation at present and could be much improved by picking the nodes to reduce more carefully (i.e. not completely at random) when I get the time.

OctTreeQuantizer

public OctTreeQuantizer()

方法详细资料

setup

public void setup(int numColors)

Initialize the quantizer. This should be called before adding any pixels.

指定者:

setup 在接口中 Quantizer

参数:

numColors - the number of colors we're quantizing to.

addPixels

public void addPixels(int[] pixels,
                      int offset,
                      int count)

Add pixels to the quantizer.

指定者:

addPixels 在接口中 Quantizer

参数:

pixels - the array of ARGB pixels

offset - the offset into the array

count - the count of pixels

getIndexForColor

public int getIndexForColor(int rgb)

Get the color table index for a color.

指定者:

getIndexForColor 在接口中 Quantizer

参数:

rgb - the color

返回:

the index

buildColorTable

public int[] buildColorTable()

Build the color table.

指定者:

buildColorTable 在接口中 Quantizer

返回:

the color table

buildColorTable

public void buildColorTable(int[] inPixels,
                            int[] table)

A quick way to use the quantizer. Just create a table the right size and pass in the pixels.

参数:

inPixels - the input colors

table - the output color table
