is_known_color()

bool xtd::drawing::color::is_known_color ( ) const

noexcept

Gets a value indicating whether this xtd::drawing::color structure is a predefined color. Predefined colors are represented by the elements of the xtd::drawing::known_color enumeration.

Returns

bool Returns true if this xtd::drawing::color was created from a predefined color by using either the from_name method or the from_known_color method; otherwise, false.

Remarks

This property does not do a comparison of the ARGB values. Therefore, when the is_known_color property is applied to a xtd::drawing::color structure that is created by using the xtd::drawing::color::from_argb method, is_known_color returns false, even if the ARGB value matches the ARGB value of a predefined color.
