Color.LabAssign method
Assigns the LAB color model
Syntax:
Sub LabAssign(ByVal L As Long, ByVal A As Long, ByVal B As Long)
Parameters:
Name Type Description
L
Long
A
Long
B
Long
Remarks:
The LabAssign method assigns the LAB color model in CorelDRAW. All three color components are applied in one step, and the color model is set to LAB. A color is an effect applied to an object that alters the object's appearance by the way it reflects light. A color model is a system that defines the number and type of colors that make up an image and that is used to organize and define colors according to a set of basic properties that can be reproduced. Black-and-white, grayscale, RGB, CMYK, and paletted are examples of popular color modes. The LAB color model is a color model created by the Commission Internationale de l'Eclairage (CIE). It contains a luminance (or lightness) component (L) and two chromatic components: "a" (green to red) and "b" (blue to yellow). The LAB color mode is based on the LAB color model.
Examples:
The following VBA example fills all shape objects with the LAB gray color.
Sub Test()
Dim s As Shape
For Each s In ActivePage.Shapes
  If s.Fill.Type = cdrUniformFill Then

 s.Fill.UniformColor.LabAssign 128, 0, 0
  End If
Next s 
End Sub
