Creates a new Color structure by using the specified sRGB alpha channel and color channel values.
Assembly: PresentationCore (in PresentationCore.dll)
public: static Color FromArgb( unsigned char a, unsigned char r, unsigned char g, unsigned char b )
The method allows you to specify the alpha channel; the FromRgb method uses a default value of 255 for the alpha channel.
The alpha channel of a color determines the amount of transparency of the color. An alpha value of 255 indicates that the color is completely opaque, and a value of 0 indicates that the color is completely transparent.
