Detailed Description

A calibrated RGB color space. A CalRGB color space (Red, Green, Blue) is a CIE-based ABC color space with only one transformation stage instead of two.

In this type of space, A, B, and C represent calibrated red, green, and blue color values. These three color components must be in the range 0.0 to 1.0; component values falling outside that range are adjusted to the nearest valid value without error indication.

Constructor & Destructor Documentation

CalRGBColorSpace(java.util.List< Double > whitePoint)

Parameters

whitePoint: java.util.List< Double >: An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.

Create a CalRGB color space.

The blackPoint defaults to [0.0, 0.0, 0.0].

The gamma defaults to [1.0, 1.0, 1.0].

The matrix defaults to [1 0 0 0 1 0 0 0 1]

CalRGBColorSpace(java.util.List< Double > whitePoint, java.util.List< Double > blackPoint, java.util.List< Double > gamma, java.util.List< Double > matrix)

Parameters

whitePoint: java.util.List< Double >: An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.
blackPoint: java.util.List< Double >: An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse black point. All three of these numbers must be non-negative.
gamma: java.util.List< Double >: An array of three numbers [ GR GG GB ] specifying the gamma for the red, green, and blue (A, B, and C) components of the color space.
matrix: java.util.List< Double >: An array of nine numbers [ XA YA ZA XB YB ZB XC YC ZC ] specifying the linear interpretation of the decoded A, B, and C components of the color space with respect to the final XYZ representation.

java.util.List< Double > getBlackPoint()

Returns:

java.util.List< Double >

An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse black point. All three of these numbers must be non-negative.

String getName()

Returns:

String

The name of the color space. A named color space may be named something like DeviceRGB. More complicated color spaces may have a name like Indexed or ICCBased.

int getNumComponents()

Returns:

int

The number of color components.

The number of components in the color space. For example, DeviceGray has 1 component, DeviceRGB has 3, and DeviceCMYK has 4.

PDFObject getPDFObject()

Returns:

PDFObject

The PDFObject associated with the color space.

Get the PDFObject associated with the color space. This may be a PDFName, PDFDict, PDFStream, or PDFArray.

java.util.List< Double > getWhitePoint()

Returns:

java.util.List< Double >

An array of three numbers specifying the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point. The numbers X and Z must be positive, and Y must be equal to 1.0.

String toString()

Returns:

String

A string describing this ColorSpace.

Convert a ColorSpace to a string representation.
