Color.HSBAssign method
Assigns the HSB color model
Syntax:
Sub HSBAssign(ByVal Hue As Long, ByVal Saturation As Long, ByVal Brightness As Long)
Parameters:
Name Type Description
Hue
Long
Saturation
Long
Brightness
Long
Remarks:
The HSBAssign method assigns the HSB color model in CorelDRAW. All three color components are applied in one step, and the color model is set to HSB. 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. HSB is a color model that approximates the way the human eye perceives color. In the HSB model, color is defined by three components: hue, saturation, and brightness. Hue determines color (yellow, orange, red, etc.), brightness determines perceived intensity (lighter or darker color), and saturation determines color depth (from dull to intense). In the HSB color model, hue (H) is expressed as a degree of rotation on a circular color wheel. Saturation (S) and brightness (B) are expressed as percentages of full intensity.
Examples:
The following VBA example creates an ellipse on the active layer in the current document.
Sub LayerActive()
ActiveLayer.CreateEllipse 3, 3, 2, 1
ActiveDocument.Selection.Shapes(1).Fill.UniformColor.HSBAssign 200, 100, 100 
End Sub
