Examples

En el ejemplo de código siguiente se muestran las propiedades A, R, Gy B de un Colory el miembro Implicit.The following code example demonstrates the A, R, G, and B properties of a Color, and the Implicit member.

Este ejemplo está diseñado para usarse con un Windows Form.This example is designed to be used with a Windows Form. Pegue el código en el formulario y llame al método ShowPropertiesOfSlateBlue desde el método de control de eventos Paint del formulario, pasando e como PaintEventArgs.Paste the code into the form and call the ShowPropertiesOfSlateBlue method from the form's Paint event-handling method, passing e as PaintEventArgs.

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;
   array<Object^>^temp0 = {a,r,g,b};
   String^ text = String::Format( "Slate Blue has these ARGB values: Alpha:{0}, "
   "red:{1}, green: {2}, blue {3}", temp0 );
   e->Graphics->DrawString( text, gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), gcnew SolidBrush( slateBlue ), RectangleF(PointF(0.0F,0.0F),this->Size) );
}
private void ShowPropertiesOfSlateBlue(PaintEventArgs e)

Remarks

El color de cada píxel se representa como un número de 32 bits: 8 bits para alfa, rojo, verde y azul (ARGB).The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). Cada uno de los cuatro componentes es un número del 0 al 255, con 0 que no representa ninguna intensidad y 255 que representa intensidad total.Each of the four components is a number from 0 through 255, with 0 representing no intensity and 255 representing full intensity. Del mismo modo, G es un valor comprendido entre 0 y 255 con 0 que representa que no es verde y 255 que representa totalmente verde.Likewise, G is a value from 0 to 255 with 0 representing no green and 255 representing fully green.
