XAML Values
- predefinedBrushName
The name of a brush defined by the Brushes class, such as Blue or Orange.
- rgb
A three-digit hexadecimal number that describes this brush's Color. 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 that describes this brush's Color. 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 that describes this brush's Color. 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 that describes this brush's Color. 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.
- scA
Single
The ScA value of this brush's Color.
- scR
Single
The ScR value of this brush's Color.
- scG
Single
The ScG value of this brush's Color.
- scB
Single
The ScB value of this brush's Color.
- profileUri
System..::.Uri
The International Color Consortium (ICC) or Image Color Management (ICM) color profile.
- alphaValue
System..::.Single
The alpha channel color value. The value range is from 0.0 through 1.0.
- colorValue
A comma-delimited list of three to eight values that represent the color channels of the color profile. The value range is from 0.0 through 1.0.
For convenience, the Brushes class provides a set of commonly used SolidColorBrush objects, such as Blue and Yellow.
Freezable Features: Because it inherits from the Freezable class, the SolidColorBrush class provides several special features: SolidColorBrush objects can be declared as resources, shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.
To paint an area with a solid color, you can use a predefined system brush, such as Red or Blue, or you can create a new SolidColorBrush and describe its Color using alpha, red, green, and blue values. In XAML, you may also paint an area with a solid color by using hexidecimal notation.
The following examples uses each of these techniques to paint a Rectangle blue.
Using a Predefined Brush
In the following example uses the predefined brush Blue to paint a rectangle blue.
<Rectangle Width="50" Height="50" Fill="Blue" />
// Create a rectangle and paint it with
// a predefined brush.
Rectangle myPredefinedBrushRectangle = new Rectangle();
myPredefinedBrushRectangle.Width = 50;
myPredefinedBrushRectangle.Height = 50;
myPredefinedBrushRectangle.Fill = Brushes.Blue;
For a list of predefined brushes, see the Brushes class.
xaml
Using Hexadecimal Notation
The next example uses 8-digit hexadecimal notation to paint a rectangle blue.
<!-- Note that the first two characters "FF" of the 8-digit
value is the alpha which controls the transparency of
the color. Therefore, to make a completely transparent
color (invisible), use "00" for those digits (e.g. #000000FF). -->
<Rectangle Width="50" Height="50" Fill="#FF0000FF" />
Using ARGB Values
The next example creates a SolidColorBrush and describes its Color using the ARGB values for the color blue.
<Rectangle Width="50" Height="50">
<Rectangle.Fill>
<SolidColorBrush>
<SolidColorBrush.Color>
<!-- Describes the brush's color using
RGB values. Each value has a range of 0-255.
R is for red, G is for green, and B is for blue.
A is for alpha which controls transparency of the
color. Therefore, to make a completely transparent
color (invisible), use a value of 0 for Alpha. -->
<Color A="255" R="0" G="0" B="255" />
</SolidColorBrush.Color>
</SolidColorBrush>
</Rectangle.Fill>
</Rectangle>
Rectangle myRgbRectangle = new Rectangle();
myRgbRectangle.Width = 50;
myRgbRectangle.Height = 50;
SolidColorBrush mySolidColorBrush = new SolidColorBrush();
// Describes the brush's color using RGB values.
// Each value has a range of 0-255.
mySolidColorBrush.Color = Color.FromArgb(255, 0, 0, 255);
myRgbRectangle.Fill = mySolidColorBrush;
For other ways of describing color, see the Color structure.
