Комментарии

Цвет каждого пикселя представлен в виде 32-разрядного числа: по 8 бит для альфа-канала, красного, зеленого и синего (ARGB). The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). Каждый из четырех компонентов — это число от 0 до 255, где 0 означает отсутствие интенсивности и 255, представляющие полную интенсивность. Each of the four components is a number from 0 through 255, with 0 representing no intensity and 255 representing full intensity. Подоб Likewise,

R — Это значение от 0 до 255 с 0, обозначающее отсутствие красного и 255, представляющее полностью красный. R is a value from 0 to 255 with 0 representing no red and 255 representing fully red.

System Colors Класс

Определение

Каждое свойство класса SystemColors является структурой Color, которая представляет собой цвет элемента изображения Windows. Each property of the SystemColors class is a Color structure that is the color of a Windows display element.

Примеры

В следующем примере кода демонстрируется использование Equality оператора и SystemColors класса. The following code example demonstrates the Equality operator and the SystemColors class. Этот пример предназначен для использования с формой Windows Forms, содержащей кнопку с именем Button1 . This example is designed to be used with a Windows Form that contains a button named Button1 . Вставьте следующий код в форму и свяжите Button1_Click метод с Click событием кнопки. Paste the following code into your form and associate the Button1_Click method with the button’s Click event.

Комментарии

Более высокая производительность достигается за счет использования свойств SystemPens классов или SystemBrushes вместо создания нового пера или кисти на основе значения из SystemColors . Better performance is achieved by using the properties of the SystemPens or SystemBrushes classes rather than creating a new pen or brush based on a value from SystemColors. Например, если вы хотите получить кисть для цвета лицевой стороны трехмерного элемента, используйте SystemBrushes.Control свойство, так как оно получает уже существующую кисть, а вызов SolidBrush конструктора со значением параметра SystemColors.Control создаст новую кисть. For example, if you wanted to get a brush for the face color of a 3-D element, use the SystemBrushes.Control property because it gets a brush that already exists, whereas calling the SolidBrush constructor with a parameter value of SystemColors.Control will create a new brush.

Color Struct

Definition

Represents an ARGB (alpha, red, green, blue) color.

Examples

The following code example demonstrates the A, R, G, and B properties of a Color, and the Implicit member.

This example is designed to be used with a Windows Form. Paste the code into the form and call the ShowPropertiesOfSlateBlue method from the form’s Paint event-handling method, passing e as PaintEventArgs.

Remarks

Named colors are represented by using the properties of the Color structure. For more information about these colors, see Colors by Name.

The color of each pixel is represented as a 32-bit number: 8 bits each for alpha, red, green, and blue (ARGB). Each of the four components is a number from 0 through 255, with 0 representing no intensity and 255 representing full intensity. The alpha component specifies the transparency of the color: 0 is fully transparent, and 255 is fully opaque. To determine the alpha, red, green, or blue component of a color, use the A, R, G, or B property, respectively. You can create a custom color by using one of the FromArgb methods.

Fields

Represents a color that is null .

Creates a Color structure from the specified 8-bit color values (red, green, and blue). The alpha value is implicitly 255 (fully opaque). Although this method allows a 32-bit value to be passed for each color component, the value of each component is limited to 8 bits.

Creates a Color structure from the four ARGB component (alpha, red, green, and blue) values. Although this method allows a 32-bit value to be passed for each component, the value of each component is limited to 8 bits.

Creates a Color structure from the specified predefined color.

Creates a Color structure from the specified name of a predefined color.

Gets the hue-saturation-lightness (HSL) lightness value for this Color structure.

Returns a hash code for this Color structure.

Gets the hue-saturation-lightness (HSL) hue value, in degrees, for this Color structure.
