finalcolors

protected byte[] finalcolors
r,g,and b components of the color table as a single array, for Java's IndexColorModel

Constructor Detail

IndexedColor

public IndexedColor(PDFColorSpace base,
                    int count,
                    PDFObject stream)
             throws java.io.IOException
create a new IndexColor PDFColorSpace based on another PDFColorSpace, a count of colors, and a stream of values. Every consecutive n bytes of the stream is interpreted as a color in the base ColorSpace, where n is the number of components in that color space.

Parameters:
base - the color space in which the data is interpreted
count - the number of colors in the table
stream - a stream of bytes. The number of bytes must be count*n, where n is the number of components in the base colorspace.
Throws:
java.io.IOException

IndexedColor

public IndexedColor(java.awt.Color[] table)
             throws java.io.IOException
create a new IndexColor PDFColorSpace based on a table of colors.

Parameters:
table - an array of colors
Throws:
java.io.IOException
Method Detail

getCount

public int getCount()
Get the number of indices


getColorComponents

public byte[] getColorComponents()
Get the table of color components


getNumComponents

public int getNumComponents()
get the number of components of this colorspace (1)

Overrides:
getNumComponents in class PDFColorSpace

getPaint

public PDFPaint getPaint(float[] components)
get the color represented by the index.

Overrides:
getPaint in class PDFColorSpace
Parameters:
components - an array of exactly one integer number whose value is between 0 and the size of the color table - 1.
Returns:
a PDFPaint object representing the closest Color to the given components.
