Leadtools Namespace : RasterColor Structure



Describes a color consisting of relative intensities of alpha, red, green, and blue.

Syntax

Visual Basic (Declaration) 
<SerializableAttribute()>
Public Structure RasterColor 
   Inherits ValueType
Visual Basic (Usage)Copy Code
Dim instance As RasterColor
C# 
[SerializableAttribute()]
public struct RasterColor : ValueType
C++/CLI 
[SerializableAttribute()]
public value class RasterColor : public ValueType

Example

Converts a .NET color to a RasterColor and back.

Visual BasicCopy Code
Public Sub Example()
 Dim rand As Random = New Random()

 ' Create a random .NET color
 Dim clr1 As Color = Color.FromArgb(rand.Next(256), rand.Next(256), rand.Next(256), rand.Next(256))

 ' Convert this color to a LEADTOOLS color
 Dim clr2 As RasterColor = RasterColor.FromGdiPlusColor(clr1)

 ' Make sure both colors are equal
 Debug.Assert(clr1.A = clr2.A)
 Debug.Assert(clr1.R = clr2.R)
 Debug.Assert(clr1.G = clr2.G)
 Debug.Assert(clr1.B = clr2.B)

 ' Convert the LEADTOOLS color back to .NET
 clr1 = clr2.ToGdiPlusColor()

 ' Make sure both colors are equal
 Debug.Assert(clr1.A = clr2.A)
 Debug.Assert(clr1.R = clr2.R)
 Debug.Assert(clr1.G = clr2.G)
 Debug.Assert(clr1.B = clr2.B)

Remarks

You can use RasterColor.FromGdiPlusColor to convert a System.Drawing.Color object to RasterColor and RasterColor.ToGdiPlusColor to convert a RasterColor object to a System.Drawing.Color.
