effects

Ultimately, what I want to achieve is a replication to some extend, of an Aero glass functionality of a WPF content control. If I apply the BlurEffect to a StackPanel that contains a TextBlock , I will have the TextBlock 's text blurred. Consider an examples: No blur and with <BlurEffect Radius="5" KernelType="Gaussian"/> But is there a WPF way to blur the background behind the panel, and not it's contents? The background of the StackPanel is a desktop, and the window that hosts it is set to AllowTransparency="True" to allow the custom-shaped look. What the background of the StackPanel? an

On many smartphones (Samsung Galaxy II being an example) when you browse through a photo gallery, its blurred copy is laid out in the background. Can this be achieved by CSS dynamically (ie. without the copy of the photo being prepared upfront saved)? Is there any kind of complex CSS image filter to blur an image? You can use CSS3 filters . They are relatively easy to implement, though are only supported on webkit at the minute. Samsung Galaxy 2's browser should support though, as I think that's a webkit browser? With CSS3 we can easily adjust an image. But remember this does not change the

I've just started learning about @ngrx/store and @ngrx.effects and have created my first effect in my Angular/Ionic app. It runs ok the first time but if I dispatch the event to the store again (i.e when clicking the button again), nothing happens (no network call is made, nothing in console logs). Is there something obvious I'm doing wrong? Here's the effect: @Effect() event_response$ = this.action$ .ofType(SEND_EVENT_RESPONSE_ACTION) .map(toPayload) .switchMap((payload) => this.myService.eventResponse(payload.eventId,payload.response)) .map(data => new SentEventResponseAction(data)) .catch(

I'm trying to use the playSoundEffect () method to play a sound effect when a button is clicked, but so far its' proved very difficult for some reason. I have defined the following. <ImageButton android:id="@+id/Button_flip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="FLIP!" android:src="@drawable/flip" android:soundEffectsEnabled="true"> </ImageButton> Then, button_flip.playSoundEffect(android.view.SoundEffectConstants.CLICK); is called in onCreate() method. But I cannot seem to get it to sound when I click the button. What am I missing here? The

Anybody has any idea how to make a fireworks effect by drawing on canvas? There is one nice example in wireworks live wallpaper (free app). There, many points move and leave trails in a star like explosion and gradually disappear. I think that there is some kind of motion blur on each point moving, which I am not sure how to create. Any ideas or links to relevant examples are welcome. That's a very abstract (and interesting) question but far too complex to answer in details. What you're really looking for is probably a sort of a modified particle system. A particle system is basically an
