to_known_color()

xtd::drawing::known_color xtd::drawing::color::to_known_color ( ) const

noexcept

Gets the xtd::drawing::known_color value of this xtd::drawing::color class.

Returns

xtd::drawing::known_color An element of the xtd::drawing::known_color enumeration, if the xtd::drawing::color is created from a predefined color by using either the xtd::drawing::color::from_name method or the xtd::drawing::color::from_known_color method; otherwise, 0.

Remarks

A predefined color is also called a known color and is represented by an element of the xtd::drawing::known_color enumeration. When the xtd::drawing::color::to_known_color method is applied to a xtd::drawing::color structure that is created by using the FromArgb method, xtd::drawing::color::to_known_color returns 0, even if the ARGB value matches the ARGB value of a predefined color. xtd::drawing::color::to_known_color also returns 0 when it is applied to a xtd::drawing::color structure that is created by using the xtd::drawing::color::from_name method with a string name that is not valid.
