WPF: RadialGradientBrush without gradient? - wpf

Question

I want to draw some circles in another circle like this:

Is there a way to tell a RadialGradientBrush not to use gradients but just fixed colors, so I can achieve this? Thanks for any hint!
(I guess this could be easily done using a DrawingBrush, I'm just wondering whether this could also be done using a RadialGradientBrush)

Answer 1

If you really, really want to do this, you can repeat the colors that you want at the offsets that you want.
For example:
<RadialGradientBrush>
<GradientStop Offset="0" Color="Black" />
<GradientStop Offset="0.25" Color="Black" />
<GradientStop Offset="0.25" Color="Red" />
<GradientStop Offset="0.75" Color="Red" />
<GradientStop Offset="0.75" Color="Salmon" />
<GradientStop Offset="1" Color="Salmon" />
</RadialGradientBrush>
That way, it will fill Black to Black from 0 to 0.25, Red to Red from 0.25 to 0.75, and Salmon to Salmon from 0.75 to 1.0.
Since the offsets match, there is no "room" for the Gradient to blend.

If you are trying to make a "bullseye" of absolute sizes, consider overlaying Ellipses in a grid instead of trying to use a brush.
<Grid>
<Grid.Resources>
<Style TargetType="{x:Type Ellipse}">
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="VerticalAlignment" Value="Stretch" />
</Style>
</Grid.Resources>
<Ellipse Width="100"
Height="100"
Fill="Salmon" />
<Ellipse Width="50"
Height="50"
Fill="Red" />
<Ellipse Width="25"
Height="25"
Fill="Black" />
</Grid>
Since they are all in the same grid (column and row are both 0 by default, but you could set them), and have their horizontal and vertical alignments set to stretch, they will simply overlap. Be sure to put the biggest one first, of course.
