Property RGBBlue As Long
Member of Color
The RGBBlue property returns or specifies the blue color value for the RGB color model in CorelDRAW. 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.
RGB is a color mode that contains three components: red (R), green (G), and blue (B). The RGB color mode is based on the RGB color model. In the RGB color mode, a value between 0 and 255 is assigned to each channel of red, green, and blue. An RGB color with the component values 0:25:118, for example, contains no red, some green, and more blue, resulting in a slightly greenish blue color. Monitors, scanners, and the human eye use RGB to produce or detect color.
The following VBA example deletes all of the shape objects with a RGB red fill.
Sub Test() |
Dim s As Shape |
For Each s In ActivePage.Shapes |
If s.Fill.Type = cdrUniformFill Then |
With s.Fill.UniformColor |
If .Type = cdrColorRGB Then |
If .RGBRed = 255 And .RGBGreen = 0 And .RGBBlue = 0 Then s.Delete |
End If |
End With |
End If |
Next s |
End Sub |
