从指定的 32 位有符号整数创建 Pixel 类型的 Unit。
[Visual Basic] Public Shared Function Pixel( _ ByVal n As Integer _ ) As Unit [C#] public static Unit Pixel( int n ); [C++] public: static Unit Pixel( int n ); [JScript] public static function Pixel( n : int ) : Unit;
参数
- n
- 表示 Unit 的长度的 32 位有符号整数。
返回值
Pixel 类型的 Unit，它表示 n 参数指定的长度。
备注
使用 Pixel 静态方法创建 Pixel 类型的 Unit，它表示由 n 参数指定的长度。
