13.画刷（Brush）

怪味豆 发表于 2024-2-1 16:32:47

在进行WPF界面设计时，我们需要在很多地方设置颜色属性，比如元素的背景色、前景色以及边框的颜色，还有形状的内部填充和笔画，这些颜色的设置在WPF中都以画刷（Brush）的形式实现。比如最常用的画刷就是SolidColorBrush，它表示一种纯色。
public abstract class Brush : Animatable, IFormattable, IResource
{
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static readonly DependencyProperty OpacityProperty;
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static readonly DependencyProperty TransformProperty;
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static readonly DependencyProperty RelativeTransformProperty;

<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> protected Brush();

<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public double Opacity { get; set; }
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public Transform Transform { get; set; }
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public Transform RelativeTransform { get; set; }

<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public Brush Clone();
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public Brush CloneCurrentValue();
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public override string ToString();
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public string ToString(IFormatProvider provider);

}Brush继承于Animatable基类和Freezable基类，说明它支持更改通知。如果改变了画刷，任何使用该画刷的控件的颜色都会自动重绘。
Opacity 属性表示它支持部分透明。
Brush一共有7个子类，下表中列出了它们的信息。
画刷名称功能说明SolidColorBrush使用单一的连续颜色填充区域LinearGradientBrush使用线性渐变绘制区域。RadialGradientBrush使用径向渐变绘制区域。焦点定义渐变的开始，而圆定义渐变的终点。ImageBrush使用图像绘制区域。VisualBrush使用一个视图绘制区域。BitmapCacheBrush绘制带有缓存的内容的区域。DrawingBrush使用包括形状、文本、视频、图像或其他绘制项等填充区域。Brush基类和子类的继承关系

SolidColorBrush纯色画刷
SolidColorBrush继承于Brush抽象类，表示用某一种颜色填充区域。从定义上看，它拥有一个Color属性，表示具体的颜色值。
public sealed class SolidColorBrush : Brush
{
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static readonly DependencyProperty ColorProperty;

<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public SolidColorBrush();
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public SolidColorBrush(Color color);

<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public Color Color { get; set; }

<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static object DeserializeFrom(BinaryReader reader);
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public SolidColorBrush Clone();
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public SolidColorBrush CloneCurrentValue();
}Color 在WPF中代表颜色值，被设计成一个结构体，主要是4个属性，即A、R、G、B，分别表示Alpha透明通道值，红色通道值、绿色通道值和蓝色通道值。它们的取值范围都是0-255

SolidColorBrush solidColorBrush = new SolidColorBrush();
//使用系统自定义的颜色
solidColorBrush.Color = Colors.Green;
//或者从Color的FromRgb成员中得到颜色
solidColorBrush.Color = Color.FromRgb(0, 0x80, 0);
grid.Background = solidColorBrush;实例化成一个资源：
<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/>
LinearGradientBrush渐变画刷
LinearGradientBrush是一个比较有意思的画刷，它可以从一种颜色过渡到另一种颜色，使被填充的区域呈现渐变效果
public sealed class LinearGradientBrush : GradientBrush{<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static readonly DependencyProperty StartPointProperty;<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public static readonly DependencyProperty EndPointProperty;<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/>public LinearGradientBrush();<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public LinearGradientBrush(GradientStopCollection gradientStopCollection);<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public LinearGradientBrush(GradientStopCollection gradientStopCollection, double angle);<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public LinearGradientBrush(Color startColor, Color endColor, double angle);<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public LinearGradientBrush(GradientStopCollection gradientStopCollection, Point startPoint, Point endPoint);<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public LinearGradientBrush(Color startColor, Color endColor, Point startPoint, Point endPoint);<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/>public Point StartPoint { get; set; }<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public Point EndPoint { get; set; }<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/>public LinearGradientBrush Clone();<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> public LinearGradientBrush CloneCurrentValue();}从定义上看，它有StartPoint 和EndPoint 两个点，表示获取和设置线性渐变的二维起始坐标和结束坐标。而它因为继承于GradientBrush基类，所以它的颜色都保存在GradientStops集合属性中。GradientStops集合中的元素类型必须为GradientStop，表示渐变中转换点的位置和颜色。所以，GradientStop拥有Color属性和Offset属性，分别表示颜色值和偏移值。
案例：
一个Grid，希望从左上角设置一个绿色，右下角设置一个蓝色，中间是两种颜色的渐变效果

RadialGradientBrush径向渐变
RadialGradientBrush径向渐变像一个圆一样，从焦点中心位置开始向四周渐变，LinearGradientBrush线性渐变具有用于定义渐变矢量的起点和终点，而径向渐变具有一个圆和一个焦点，用于定义渐变行为。圆定义渐变的终点。换句话说，渐变停止点为 1.0 定义圆周的颜色。焦点定义渐变的中心。渐变停止点为 0.0 定义焦点处的颜色。

在上面的代码中，处于圆中心的白色渐变点由GradientOrigin属性控制，如果将值改成：GradientOrigin="0.25,0.25"，那么它会呈现下面的样子。

根据这个特性，我们可以实现一个有趣的示例。那就是当鼠标移动到椭圆内，这个径向渐变的起点坐标跟随鼠标位置变化而变化。

ImageBrush图像画刷
ImageBrush表示使用图像绘制区域。它继承于TileBrush抽象基类，另外，DrawingBrush和VisualBrush也继承于TileBrush抽象基类。
TileBrush 有三种不同类型，其中每一种都使用不同类型的内容进行绘制。下面列出它3个子类的情况。

[*]若使用ImageBrush子类，则画刷的填充内容是图像；
[*]若使用DrawingBrush子类，则画刷的填充内容是绘图；
[*]若使用VisualBrush子类，则画刷的填充内容是视觉对象（视觉树或控件）；

Stretch 属性：获取或设置内容如何拉伸。
Viewbox 属性：获取或设置图块中内容的位置和尺寸。
Viewport 属性：获取或设置基本图块的位置和尺寸。它的类型是Rect，也就是用它来指定截取原图片的某个区域进行填充，这个区域的设置可以用绝对值和相对值两种方式设置，对应属性是ViewboxUnits，它有两个值，Absolute表示取绝对坐标，RelativeToBoundingBox表示取相对坐标。
AlignmentY属性：获取或设置基本图块的垂直对齐方式。
AlignmentX属性：获取或设置基本图块的垂直水平方式。
ViewboxUnits属性：获取或设置Viewbox的值是相对内容的边界框而言，还是绝对值。
ViewportUnits属性：获取或设置Viewport的值是否是相对于输出区域的大小。

<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> 在上面的代码中，我们给Grid控件设置了一个ImageBrush 图像画刷，并设置Stretch为UniformToFill，即自适应填充，同时设置了Viewport。那么它运行之后呈现的效果如下：

此时的Grid的背景其实就是一张图片。我们给Window对象的MouseWheel事件订阅了一个回调函数，并在其实改变了Viewport的宽度和高度。滚动鼠标的滚轮，此时Grid的背景图像的填充将会呈现如下的样子：
private void Window_MouseWheel(object sender, MouseWheelEventArgs e){<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> double offset = e.Delta / 3600.0;<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>

<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> ImageBrush imageBrush = grid.Background as ImageBrush;<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>
</Window.Resources>
<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> Rect rect = imageBrush.Viewport;<Window.Resources>
 <SolidColorBrush x:Key="BackgroundBrush" Color="#123456"/>

<Grid x:Name="grid" Background="{StaticResource BackgroundBrush}"/> if (rect.Width + offset
