Property LabComponentB As Long
Member of Color
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.
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 |
