Inheritance diagram for xtd::drawing::imaging::color_palette:

Definition

Defines an array of colors that make up a color palette. The colors are 32-bit ARGB colors. Not inheritable.

Namespace: xtd::drawing::imaging

Library: xtd.drawing

Remarks: You are not allowed to construct a color_palette object directly. If you created a color_palette object, you could then manipulate the palette size for a particular image, which is not allowed. Use the image.palette property to obtain a color_palette object.; The colors in the palette are limited to 32-bit ARGB colors. A 32-bit ARGB color has 8 bits each for alpha, red, green, and blue values. The lowest 8 bits make up the blue bit, the next 8 bits are green, the next 8 bits are red, and the most significant 8 bits are alpha. This means each component can vary from 0 to 255. Fully on is 255 and fully off is 0. Alpha is used to make the color value transparent (alpha = 0) or opaque (alpha = 255). The number of intensity levels in the image can be increased without increasing the number of colors used. This process creates what is called a halftone, and it offers increased contrast at a cost of decreased resolution.

Public Properties
xtd::array< color >	entries () const noexcept
	Gets an array of color structures.

int32	flags () const noexcept
	Gets a value that specifies how to interpret the color information in the array of colors.

Public Methods
bool	equals (const object &obj) const noexcept override
	Determines whether the specified object is equal to the current object.

bool	equals (const color_palette &other) const noexcept override
	Determines whether the specified object is equal to the current object.

xtd::size	get_hash_code () const noexcept override
	Serves as a hash function for a particular type.

Additional Inherited Members
	object ()=default
	Create a new instance of the ultimate base class object.

virtual type_object	get_type () const noexcept
	Gets the type of the current instance.

template<class object_t>
xtd::unique_ptr_object< object_t >	memberwise_clone () const
	Creates a shallow copy of the current object.

virtual xtd::string	to_string () const noexcept
	Returns a xtd::string that represents the current object.

virtual bool	equals (const color_palette &) const noexcept=0
	Indicates whether the current object is equal to another object of the same type.

template<class object_a_t, class object_b_t>
static bool	equals (const object_a_t &object_a, const object_b_t &object_b) noexcept
	Determines whether the specified object instances are considered equal.

template<class object_a_t, class object_b_t>
static bool	reference_equals (const object_a_t &object_a, const object_b_t &object_b) noexcept
	Determines whether the specified object instances are the same instance.

Member Function Documentation

◆ entries()

xtd::array< color > xtd::drawing::imaging::color_palette::entries ( ) const

noexcept

Gets an array of color structures.

Returns: The array of color structure that make up this color_palette.

◆ flags()

int32 xtd::drawing::imaging::color_palette::flags ( ) const

noexcept

Gets a value that specifies how to interpret the color information in the array of colors.

Remarks

The following flag values are valid:

0x00000001 The color values in the array contain alpha information.
0x00000002 The colors in the array are grayscale values.
0x00000004 The colors in the array are halftone values.

◆ equals() [1/2]

bool xtd::drawing::imaging::color_palette::equals ( const object & obj ) const

overridevirtualnoexcept

Determines whether the specified object is equal to the current object.

Parameters

obj	The object to compare with the current object.

Returns: true if the specified object is equal to the current object. otherwise, false.

Reimplemented from xtd::object.

◆ equals() [2/2]

bool xtd::drawing::imaging::color_palette::equals ( const color_palette & other ) const

overridenoexcept

Determines whether the specified object is equal to the current object.

Parameters

other The object to compare with the current object.

Returns: true if the specified object is equal to the current object. otherwise, false.

◆ get_hash_code()

xtd::size xtd::drawing::imaging::color_palette::get_hash_code ( ) const

overridevirtualnoexcept

Serves as a hash function for a particular type.

Returns: A hash code for the current object.

Reimplemented from xtd::object.
