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.
