  • Make your background alive with built-in XAML animations 🙉
  • Powered by Nuget


Magic Gradients are available via NuGet:


Install into shared project, no additional setup required.

Drawing gradient

To draw a gradient add GradientView control to your XAML page and create LinearGradient or RadialGradient as direct content.

        <magic:GradientStop Color="Red" />
        <magic:GradientStop Color="Yellow" />

It is also possible to add collection of gradients. You can mix linear and radial gradients, use transparency in color definitions to get blend effect.

        <magic:LinearGradient Angle="45">
            <magic:GradientStop Color="Orange" Offset="0" />
            <magic:GradientStop Color="#ff0000" Offset="0.6" />
        <magic:LinearGradient Angle="90">
            <magic:GradientStop Color="#33ff0000" Offset="0.4" />
            <magic:GradientStop Color="#ff00ff00" Offset="1" />

You can also build gradient in C# using GradientBuilder with Fluent API:

 var gradients = new GradientBuilder()
    .AddLinearGradient(g => g
        .AddStop(Color.Red, Offset.Prop(0.2))
        .AddStop(Color.Blue, Offset.Prop(0.4)))
    .AddRadialGradient(g => g
        .Circle().At(0.5, 0.5, o => o.Proportional())
        .Radius(200, 200, o => o.Absolute())
        .AddStops(Color.Red, Color.Green, Color.Blue))
    .AddCssGradient("linear-gradient(red, orange)")

To apply gradient created in C#, you can use ToSource() extension method:

 var source = new GradientBuilder()
    .AddLinearGradient(g => g
        .AddStops(Color.Red, Color.Green, Color.Blue))

gradientView.GradientSource = source;

Discover amazing backgounds


In Magic Gradients repository you can find Magic Playground, a Xamarin.Forms app for browsing and creating gradients visually. Android, iOS and UWP are supported.

Be sure to check out the Gallery. It contains over 1700+ samples 🙉 from Gradient Magic, ready to use in any Xamarin.Forms app. Find your best, pick and copy over to your app.

Styling with CSS

Magic Gradients supports CSS functions. CSS gradient can be embeded in XAML inline:

                linear-gradient(242deg, red, green, orange)

Styling from CSS stylesheet is also possible:

<magic:GradientView StyleClass="myGradient" />
.myGradient {
    background: linear-gradient(90deg, rgb(235, 216, 9), rgb(202, 60, 134));

CSS can be also set via C#:

gradientView.GradientSource = CssGradientSource.Parse("linear-gradient(red, green, blue)");

radial-gradient(circle at top left, red, green);
radial-gradient(circle 100px at 70% 20%, red, green);           // one radius for circle
radial-gradient(ellipse closest-corner at 30% 80%, red, green);
radial-gradient(ellipse 200px 300px at 50% 60%, red, green);    // two radiuses for ellipse

Play with CSS

You can play around with CSS functions live in Magic Playground app, Hot Reload 🔥 included.

Animations (preview)

Timeline property Values
Target {x:Reference myGradient} Reference to animated element.
Duration 3000 Length of single loop (in ms).
Delay 200 Time before animations starts (in ms).
Easing {x:Static Easing.SinInOut} Easing function.
RepeatBehavior 1x, 3x, Forever How many times animation must be repeated.
AutoReverse True, False If true, next loop will be animated backwards.

Running animation

Run automatically:

        <anim:DoubleAnimation ... />

Control animation from view model:

    <anim:AnimateTrigger IsRunning="{Binding IsRunning}">
         <anim:PointAnimation ... />

AnimateTrigger is a MarkupExtension. It's shorter way of creating DataTrigger with BeginAnimation and EndAnimation as EnterActions and ExitActions.

Property animations

With this type of animation you can animate single property between two values defined as From and To.

Properties Value
TargetProperty magic:GradientStop.Color Animated property with full namespace.
From Value matching TargetProperty type Value when animation starts.
To Value matching TargetProperty type Value when animation ends.

Animate color sample:

<anim:ColorAnimation Target="{x:Reference AnimColor}" 
                     From="Red" To="Yellow" 
                     AutoReverse="True" />

Built-in property types:

ColorAnimation, DimensionsAnimation, DoubleAnimation, IntegerAnimation, OffsetAnimation, PointAnimation, ThicknessAnimation

For custom types, see Custom animation types.


Attached properties Values
anim:Storyboard.BeginAt from 0 to 1 Start animation at given point of Storyboard.
anim:Storyboard.FinishAt from 0 to 1 End animation at given point of Storyboard.

Animate two colors at different times:

<anim:Storyboard Duration="4000" RepeatBehavior="Forever">
    <anim:ColorAnimation Target="{x:Reference Color1}" 
                         From="White" To="Red" 
                         AutoReverse="True" />
    <anim:ColorAnimation Target="{x:Reference Color2}" 
                         From="LightGray" To="DarkRed" 
                         AutoReverse="True" />

KeyFrame animations


<Type>KeyFrame properties:

  • KeyTime - time when value is applied to animated target
  • Value - of type <Type>
  • Easing - easing function

Move radial circle between corners, at different times:

<anim:PointAnimationUsingKeyFrames Target="{x:Reference Radial2}" 
    <anim:PointKeyFrame KeyTime="1000" Value="0.9,0.1" />
    <anim:PointKeyFrame KeyTime="1500" Value="0.9,0.9" />
    <anim:PointKeyFrame KeyTime="2500" Value="0.1,0.9" Easing="{x:Static Easing.SinInOut}" />
    <anim:PointKeyFrame KeyTime="3000" Value="0.1,0.1" />

Advanced features

Color positions

Similar to CSS, with Magic Gradient you can posion each color with proportional value or by absolute pixels.

        <magic:GradientStop Color="Red" />
        <magic:GradientStop Color="Yellow" Offset="100px" />
        <magic:GradientStop Color="Green" Offset="40%" />
        <magic:GradientStop Color="Blue" Offset="0.8" />

Offset types:

  • 0.3, 30% - proportional, Offset.Prop(0.3) in code
  • 200px - absolute, Offset.Abs(200) in code
  • leave blank - each undefined offset will be calculated like in CSS

Backgroud size and position

GradientView let's you specify size of the background with GradientSize property:

<GradientView GradientSource="..." GradientSize="0.6,0.6">
<GradientView GradientSource="..." GradientSize="200px,200px">

Proportional and absolute values are supported. Size can also be set from CSS:

.myGradient {
    background: ...;
    background-size: 60px 60px;

When size is set, gradient will be tiled to fill available space. You can change tile mode with GradientRepeat property. Supported values:

  • Repeat, repeat
  • RepeatX, repeat-x
  • RepeatY, repeat-y
  • NoRepeat, no-repeat

Repeat mode can be set from CSS as well:

.myGradient {
    background: ...;
    background-size: 60px 60px;
    background-repeat: repeat-x;

Custom animation types

  • create ITweener implementation
public class DoubleTweener : ITweener<double>
    public double Tween(double @from, double to, double progress)
        return from + (to - from) * progress;
  • define animations
public class DoubleAnimation : PropertyAnimation<double>
    public override ITweener<double> Tweener { get; } = new DoubleTweener();

public class DoubleAnimationUsingKeyFrames : PropertyAnimationUsingKeyFrames<double>
    public override ITweener<double> Tweener { get; } = new DoubleTweener();

public class DoubleKeyFrame : KeyFrame<double> { }
