FromKnownColor Method

Summary

Creates a new RasterColor structure from a known color.

Syntax

C++

[CLSCompliantAttribute(false)] 
public static RasterColor FromKnownColor( 
   RasterKnownColor knownColor 
)

<CLSCompliantAttribute(False)> 
Public Shared Function FromKnownColor( _ 
   ByVal knownColor As Leadtools.RasterKnownColor _ 
) As Leadtools.RasterColor

[CLSCompliantAttribute(false)] 
public: 
static Leadtools.RasterColor FromKnownColor(  
   Leadtools.RasterKnownColor knownColor 
)

Parameters

knownColor
One of the RasterKnownColor enumeration members.

Return Value

The new RasterColor object.

Remarks

You can use the RasterKnownColor enumeration to construct RasterColor objects from colors known by name.

Example

using Leadtools; 
 
public void FromKnownColorExample() 
{ 
   // Create a yellow color (R = 255, G = 255, B = 0) 
   RasterColor clr1 = new RasterColor(255, 255, 0); 
 
   // Now create the same color using the "Yellow" known color 
   RasterColor clr2 = RasterColor.FromKnownColor(RasterKnownColor.Yellow); 
 
   // Make sure both colors have the same value 
   Assert.IsTrue(clr1.A == clr2.A); 
   Assert.IsTrue(clr1.R == clr2.R); 
   Assert.IsTrue(clr1.G == clr2.G); 
   Assert.IsTrue(clr1.B == clr2.B); 
}

Imports Leadtools 
 
Public Sub FromKnownColorExample() 
   ' Create a yellow color (R = 255, G = 255, B = 0) 
   Dim clr1 As New RasterColor(255, 255, 0) 
 
   ' Now create the same color using the "Yellow" known color 
   Dim clr2 As RasterColor = RasterColor.FromKnownColor(RasterKnownColor.Yellow) 
 
   ' Make sure both colors have the same value 
   Debug.Assert(clr1.A = clr2.A) 
   Debug.Assert(clr1.R = clr2.R) 
   Debug.Assert(clr1.G = clr2.G) 
   Debug.Assert(clr1.B = clr2.B) 
End Sub
