Color. From Rgb(Byte, Byte, Byte) Метод
Определение
Создает новую структуру Color с использованием заданных значений цветовых каналов sRGB . Creates a new Color structure by using the specified sRGB color channel values.
Параметры
Красный канал sRGB — R — нового цвета. The sRGB red channel, R, of the new color.
Зеленый канал sRGB — G — нового цвета. The sRGB green channel, G, of the new color.
Синий канал sRGB — B — нового цвета. The sRGB blue channel, B, of the new color.
Возвращаемое значение
Структура Color с заданными значениями и значением альфа-канала, равным 255. A Color structure with the specified values and an alpha channel value of 255.
Примеры
В следующем примере показано, как использовать FromRgb метод для создания Color структуры. The following example shows how to use the FromRgb method to create a Color structure.
Комментарии
FromArgbМетод позволяет указать альфа-канал; FromRgb метод использует значение по умолчанию 1 для альфа-канала. The FromArgb method allows you to specify the alpha channel; the FromRgb method uses a default value of 1 for the alpha channel.
Альфа-канал цвета определяет степень прозрачности цвета. The alpha channel of a color determines the amount of transparency of the color. Альфа-значение 1 указывает, что цвет является полностью непрозрачным, а значение 0 означает, что цвет полностью прозрачен. An alpha value of 1 indicates that the color is completely opaque, and a value of 0 indicates that the color is completely transparent.
Каналы sRGB ( A ,, R G , B ) и каналы ScRGB ( ScA , ScR , ScG , ScB ) Color структуры являются синхронизированными свойствами. The sRGB channels (A, R, G, B) and the ScRGB channels (ScA, ScR, ScG, ScB) of the Color structure are synchronized properties. Например, при R изменении канала Red цвета sRGB красный канал цветового ScRGB преобразуется ScR в эквивалентное значение. For example, when R, the sRGB red channel, is modified the ScRGB red channel, ScR, is transformed to the equivalent value.

Remarks
XAML Attribute Usage
XAML Values
predefinedColor
One of the colors predefined by the Colors class.
rgb
A three-digit hexadecimal number. The first digit specifies the color’s R value, the second digit specifies the G value, and the third digit specifies the B value. For example, 00F .
argb
A four-digit hexadecimal number. The first digit specifies the color’s A value, the second digit specifies its R value, the next digit specifies the G value, and the final digit specifies its B value. For example, F00F .
rrggbb
A six-digit hexadecimal number. The first two digits specify the color’s R value, the next two specify its G value, and the final two specify its B value. For example, 0000FF .
aarrggbb
An eight-digit hexadecimal number. The first two digits specify the color’s A value, the next two specify its R value, the next two specify its G value, and the final two specify its B value. For example, FF0000FF .
