Method Detail

getNumberOfComponents

public int getNumberOfComponents()
                          throws java.io.IOException

This will return the number of color components. This will return the number of color components in the base color.

Specified by:

getNumberOfComponents in class PDColorSpace

Returns:

The number of components in this color space.

Throws:

java.io.IOException - If there is an error getting the number of color components.

getName

public java.lang.String getName()

This will return the name of the color space.

Specified by:

getName in class PDColorSpace

Returns:

The name of the color space.

createColorSpace

public java.awt.color.ColorSpace createColorSpace()
                                           throws java.io.IOException

Create a Java colorspace for this colorspace.

Specified by:

createColorSpace in class PDColorSpace

Returns:

A color space that can be used for Java AWT operations.

Throws:

java.io.IOException - If there is an error creating the color space.

createColorModel

public java.awt.image.ColorModel createColorModel(int bpc)
                                           throws java.io.IOException

Create a Java color model for this colorspace.

Specified by:

createColorModel in class PDColorSpace

Parameters:

bpc - The number of bits per component.

Returns:

A color model that can be used for Java AWT operations.

Throws:

java.io.IOException - If there is an error creating the color model.

getBaseColorSpace

public PDColorSpace getBaseColorSpace()
                               throws java.io.IOException

This will get the color space that acts as the index for this color space.

Returns:

The base color space.

Throws:

java.io.IOException - If there is error creating the base color space.

setBaseColorSpace

public void setBaseColorSpace(PDColorSpace base)

This will set the base color space.

Parameters:

base - The base color space to use as the index.

getHighValue

public int getHighValue()

Get the highest value for the lookup.

Returns:

The hival entry.

setHighValue

public void setHighValue(int high)

This will set the highest value that is allowed. This cannot be higher than 255.

Parameters:

high - The highest value for the lookup table.

lookupColor

public int lookupColor(int componentNumber,
                       int lookupIndex)
                throws java.io.IOException

This will perform a lookup into the color lookup table.

Parameters:

componentNumber - The component number, probably 1,2,3,3.

lookupIndex - The zero-based index into the table, should not exceed the high value.

Returns:

The value that was from the lookup table.

Throws:

java.io.IOException - If there is an error looking up the color.

setLookupColor

public void setLookupColor(int componentNumber,
                           int lookupIndex,
                           int color)
                    throws java.io.IOException

This will set a color in the color lookup table.

Parameters:

componentNumber - The component number, probably 1,2,3,3.

lookupIndex - The zero-based index into the table, should not exceed the high value.

color - The color that will go into the table.

Throws:

java.io.IOException - If there is an error looking up the color.
