透明背景和mouseEnter按钮 - WPF

Question

我必须创建一个带图像的按钮，当我将光标移到它上面时，帐户图标必须改变颜色，但我不知道该怎么做，因为现在当我传递按钮时改变整个背景。

没有光标的图像

带光标的图像

我的按钮代码是：

<Style TargetType="{x:Type Button}" x:Key="TestAccountButton" BasedOn="{StaticResource Hoverless }" >
    <Setter Property="WindowChrome.IsHitTestVisibleInChrome" Value="True"/>
    <Setter Property="Padding" Value="10"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ButtonBase}">
                <Border Padding="{TemplateBinding Padding}" Background="{TemplateBinding Background}">
                    <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" />
                </Border>
                <ControlTemplate.Triggers>
                    <!--MouseEnter-->
                    <EventTrigger RoutedEvent="MouseEnter">
                        <BeginStoryboard>
                            <Storyboard>
                                <ColorAnimation To="#3a3a3a" Duration="0:0:0.3" Storyboard.TargetProperty="Background.Color"/>
                            </Storyboard>
                        </BeginStoryboard>
                    </EventTrigger>
                    <!--MouseLeave-->
                    <EventTrigger RoutedEvent="MouseLeave">
                        <BeginStoryboard>
                            <Storyboard>
                                <ColorAnimation To="White" Duration="0:0:0.3" Storyboard.TargetProperty="Background.Color"/>
                            </Storyboard>
                        </BeginStoryboard>
                    </EventTrigger>
                </ControlTemplate.Triggers>

            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

    <Style TargetType="{x:Type Button}" x:Key="Hoverless">

            <ControlTemplate TargetType="{x:Type Button}">
