我有一个警报列表。当警报被激活时,它被要求使它们更加明显。当警报状态发生变化时,我想在物品周围创建一个脉冲外发光几秒钟然后消失。
我遇到的问题是,我似乎无法在我需要时出现DropShadowEffect。我尝试将不透明度设置为0,将颜色设置为透明但是它似乎禁用了动画。我考虑过使用样式触发器添加效果但是我不确定在动画完成后你将如何删除它?
有关如何完成此任务的任何建议?
<Rectangle Grid.Column="1" Grid.Row="0">
<Rectangle.Effect>
<DropShadowEffect ShadowDepth="0" BlurRadius="0" Opacity="0" Color="White" />
</Rectangle.Effect>
<Rectangle.Style>
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding Value, Converter={StaticResource AlarmConverter}, IsAsync=True}" Value="true">
<DataTrigger.EnterActions>
<BeginStoryboard>
<Storyboard FillBehavior="Stop" >
<DoubleAnimation Storyboard.TargetProperty="Effect.Opacity" To="1" FillBehavior="Stop" />
<ColorAnimation Storyboard.TargetProperty="Effect.Color" To="White" FillBehavior="Stop" />
<DoubleAnimation Storyboard.TargetProperty="Effect.BlurRadius" From="0" To="20" RepeatBehavior="3x" FillBehavior="Stop" />
</Storyboard>

更新 以下是屏幕一部分的示例。由于担心安全问题,我不得不从屏幕截图中删除文本和其他方面,道歉。我将大部分通用文本替换为仍然提供上下文。另一件需要注意的事情是,一般情况下,这不会在普通显示器上运行。它通常与非常长的非常大的视频墙上的其他屏幕一起显示。
带有Binding Limits字样的警报(第一个字被移除,Text不会像这样经常坐下)有一个合理的动画滚动渐变,取代了简单的闪烁。此外,在这种情况下的警报状态导致形状旋转。
反馈是当警报状态第一次改变时(从绿色变为黄色或橙色变为红色等),他们想要一些额外的指示。我有一些不同的想法。我的第一个尝试动画文本,使其扩大一点几乎脉动。然而,当我尝试它时,它非常明显地向右和向下扩展并且没有真正地给出了#34; Swelling&#34;我希望的效果。
我在这里问的另一个想法是可能为闹钟项周围的发光边框设置动画。当状态改变时,某些东西会变亮,然后变暗3或4倍。不过,我对其他想法持开放态度。我非常喜欢WPF中的动画功能,但我发现很难用它来表达我的想法。 (我认为会随着时间而来)
更新 尝试使笔触和笔触厚度以及效果具有动画效果,同时它有助于Glow突出边界过于坚硬和明显,尤其是当警报颜色为红色时。

更新 演示整个警报的外部发光,它被认为太微妙了。我现在正在接受跳舞7点的想法......(不是真的)

好的amigo,所以我今天早上花了大约15-20分钟继续进行,并将我过去用过的一些随机样式放在一起作为通知类型的东西。我猜你所展示的模拟只是一个非常粗略的例子,因此如果不知道它看起来是什么样子很难与设计师想要的风格相匹配。
然而,我想你可以使用这些例子来了解创意果汁如何/走的路线,只是尝试一些你可以快速轻松地做的事情。如果你想要一个更漂亮/更精确的例子,你将需要分享真实的屏幕等。动画和东西可以应用于其他对象,如图标和东西,但是对于这个例子,我只是把它们扔在一些盒子里。
这些来自我自己的一些技巧,自由使用它们,我有更多不同的技术我可以告诉你如果你也想要但是如果我们太过介入,那么这种深入的建议就是我如何谋生,所以可能必须至少收取一箱啤酒或其他东西;)
无论如何,把它放在一个窗口中,我只是用一个新鲜的快速wpf项目。所以你只需将它们粘贴并运行它们就可以开始加载。
我发现要避免的主要问题是,在大规模动画中使用渐变和各种像素着色器这样的东西很糟糕。但是这样的事情似乎没那么好。
OUTPUT(无论如何,在视觉示例中都是波动的.gif动画样式。):
