Using a StaticResource SolidColorBrush to define the Gradient Stop Colors

阅读更多关于 Using a StaticResource SolidColorBrush to define the Gradient Stop Colors

问题 I am creating some wpf resource dictionaries with all the styles for an application! I have a few LinearGradientBrush es, where the color is set directly in the L inearGradientBrush reference as GradientStop s. However, I want to have a predefined set of colors that I can use a a reference for each GradientStop , so that changing the color scheme for the application is a matter of changing the values of the SolidColorBrush es: <SolidColorBrush Color="#5A5A5A" x:Key="colorbrushMedium" />

Animation change from LinearGradientBrush to SolidColorBrush

Is it possible with an animation to change the Ellipse.Fill from a LinearGradientBrush to a SolidColorBrush or change the gradientStops within the LinearGradientBrush? Y.Yanavichus Maybe you should use two ellipses and dynamically change their opacity. You can animate the individual gradient stops of a gradient brush (and by setting them to the same color, you'd get a 'solid' color) This is an example of animating the gradient set to the Panel.Background of some target: <Storyboard> <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background). (GradientBrush.GradientStops)[0].

I have a brush that colors the background of a header. I like the way the brush looks but would like it to fade to transparent in the bottom third. Any ideas how to do this? <LinearGradientBrush x:Key="HeaderBackgroundBrush" EndPoint=".5,1" StartPoint="1,0"> <GradientStop Color="#006699" Offset="1"/> <GradientStop Color="#80A8CC" Offset="0.5"/> </LinearGradientBrush> I'm not sure you can do it by working only at the brush level, however you could apply an OpacityMask to your control: <LinearGradientBrush x:Key="HeaderBackgroundOpacityMask" StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="
