Syntax
public LabColorSpace( string resourceID, double[] whitePoint, double[] blackPoint, double[] range )
Parameters
- resourceID
- Type: SystemString
The id. - whitePoint
- Type: SystemDouble
The white point. An array of three numbers [XW YW ZW] that shall specify the tristimulus value, in the CIE 1931 XYZ space, of the diffuse white point; The numbers XW and ZW shall be positive, and YW shall be 1.0. - blackPoint
- Type: SystemDouble
The black point. An array of three numbers [XB YB ZB] that shall specify the tristimulus value, in the CIE 1931 XYZ space, of the diffuse black point; All three of these numbers shall be non-negative. Default value: [0.0 0.0 0.0]. - range
- Type: SystemDouble
The range. An array of four numbers [amin amax bmin bmax] that shall specify the range of valid values for the a* and b* (B and C) components of the colour space—that is, amin <= a* <= amax and bmin <= b* <= bmax Component values falling outside the specified range shall be adjusted to the nearest valid value without error indication. Default value: [−100 100 −100 100].
Examples
C#
// register LAB color space as a resource document.ResourceManager.RegisterResource(new LabColorSpace("CS_LAB", new double[] { 2.42, 1.0, 0.81 }, new double[] { 0.72, 0.09, 0.31 }, new double[]{-10,10,-10,10})); // set color space page.Content.SetNonStrokingColorSpace("CS_LAB"); page.Content.SetNonStrokingColor(333, 456, 123); // set color page.Content.SetStrokingColorSpace("CS_LAB"); page.Content.SetStrokingColor(45, -124, 90);
