Public Properties
int32	threshold
	Gets or sets the threshold value (from 0 to 765).
color	upper_color
	Gets or sets the color used when RGB color is upper the threshold value.
color	lower_color
	Gets or sets the color used when RGB color is under or equal the threshold value.

Public Constructors
	bitonal_effect ()=default

	bitonal_effect (int32 threshold, color upper_color, color lower_color)
	Initialise the new instance of xtd::drawing::imaging::bitonal_effect object with specified threshold, upper color, and lower color.

Protected Methods
auto	apply (xtd::drawing::image &image) const -> void override
	Apply the effect.

Additional Inherited Members

virtual auto	equals (const object &obj) const noexcept -> bool
	Determines whether the specified object is equal to the current object.
virtual auto	get_hash_code () const noexcept -> xtd::usize
	Serves as a hash function for a particular type.
virtual auto	get_type () const noexcept -> type_object
	Gets the type of the current instance.
template<typename object_t>
auto	memberwise_clone () const -> xtd::unique_ptr_object< object_t >
	Creates a shallow copy of the current object.
virtual auto	to_string () const -> xtd::string
	Returns a xtd::string that represents the current object.
template<typename object_a_t, typename object_b_t>
static auto	equals (const object_a_t &object_a, const object_b_t &object_b) noexcept -> bool
	Determines whether the specified object instances are considered equal.
template<typename object_a_t, typename object_b_t>
static auto	reference_equals (const object_a_t &object_a, const object_b_t &object_b) noexcept -> bool
	Determines whether the specified object instances are the same instance.
	abstract_object ()=default

Member Data Documentation

threshold

int32 xtd::drawing::imaging::effects::bitonal_effect::threshold

Gets or sets the threshold value (from 0 to 765).

Parameters

threshold

The threshold value (from 0 to 765).

Remarks

The threshold is the sum of the RGB components.

upper_color

color xtd::drawing::imaging::effects::bitonal_effect::upper_color

Gets or sets the color used when RGB color is upper the threshold value.

Parameters

upper_color

The color used when RGB color is upper the threshold value.

lower_color

color xtd::drawing::imaging::effects::bitonal_effect::lower_color

Gets or sets the color used when RGB color is under or equal the threshold value.

Parameters

lower_color

The color used when RGB color is under or equal the threshold value.
