Color.B Property
.NET Framework (current version)
Gets the blue component value of this Color structure.
Assembly: System.Drawing (in System.Drawing.dll)
The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). Each of the four components is a number from 0 through 255, with 0 representing no intensity and 255 representing full intensity. Likewise, B is a value from 0 to 255 with 0 representing no blue and 255 representing fully blue.
The following code example demonstrates the A, R, G, and B properties of a Color, and the Implicit(Size to SizeF) member.
This example is designed to be used with a Windows Form. Paste the code into the form and call the ShowPropertiesOfSlateBlue method from the form's Paint event-handling method, passing e as PaintEventArgs.
private void ShowPropertiesOfSlateBlue(PaintEventArgs e) { Color slateBlue = Color.FromName("SlateBlue"); byte g = slateBlue.G; byte b = slateBlue.B; byte r = slateBlue.R; byte a = slateBlue.A; string text = String.Format("Slate Blue has these ARGB values: Alpha:{0}, " + "red:{1}, green: {2}, blue {3}", new object[]{a, r, g, b}); e.Graphics.DrawString(text, new Font(this.Font, FontStyle.Italic), new SolidBrush(slateBlue), new RectangleF(new PointF(0.0F, 0.0F), this.Size)); }
