com.github.jaiimageio.jpeg2000.impl.Box

com.github.jaiimageio.jpeg2000.impl.ColorSpecificationBox

public class ColorSpecificationBox
extends Box

This class is defined to represent a Color Specification Box of JPEG JP2 file format. A Channel Definition Box has a length, and a fixed type of "colr". Its content contains the method to define the color space, the precedence and approximation accuracy (0 for JP2 files), the enumerated color space, and the ICC color profile if any.

Method Detail

getElementNames

public static String[] getElementNames()

This method will be called by the getNativeNodeForSimpleBox of the class Box to get the element names.

getMethod

public byte getMethod()

Returns the method to define the color space.

getPrecedence

public byte getPrecedence()

Returns Precedence.

getApproximationAccuracy

public byte getApproximationAccuracy()

Returns ApproximationAccuracy.

getEnumeratedColorSpace

public int getEnumeratedColorSpace()

Returns the enumerated color space.

getICCProfile

public ICC_Profile getICCProfile()
