Color.LabComponentB property
Gets or sets the LAB B color value
Syntax:
Property Get LabComponentB() As Long
Property Let LabComponentB(ByVal Value As Long)
Remarks:
The LabComponentB property returns or specifies the B component for the LAB color model in CorelDRAW. This property sets one of two chromatic components in the LAB color model. "B" refers to a range of colors between blue and yellow. 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 isused 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 and displays the LAB component B value in a message box.
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
MsgBox s.Fill.UniformColor.LabComponentB 
End Sub
