Detailed Description

Represents an ARGB (alpha, red, green, blue) color.

Remarks
Named colors are represented by using the properties of the xtd::drawing::color structure. For more information about these colors, see Colors by Name.
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. The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. To determine the alpha, red, green, or blue component of a color, use the A, R, G, or B property, respectively. You can create a custom color by using one of the from_argb methods
Examples
The following code example demonstrates the A, R, G, and B properties of a xtd::drawing::color, and the Implicit(size to size_f) member.
This example is designed to be used with a Windows Form (xtd::forms). Paste the code into the form and call the show_properties_of_slate_blue method from the form's paint event-handling method, passing e as paint_event_args.
void show_properties_of_slate_blue(xtd::forms::paint_event_args& e) {
byte g = slate_blue.g();
byte b = slate_blue.b();
byte r = slate_blue.r();
byte a = slate_blue.a();
string text = xtd::strings::format("Slate blue has these ARGB values: alpha:{0}, red:{1}, green: {2}, blue {3}", a, r, g, b);
}
