Using a .GIF animation as the splash screen in WP7 application - c#

I have an animated .GIF image that I created with http://ajaxload.info/ and some editing. I would like to set the resulting icon as the splash screen in my app, which can take a few seconds to load.I don't think that I can set the icon as the SplashScreenImage.jpg (GIF != JPG) and I'm not sure how to view the image as a MediaElement either. (I would show the image while the main Canvas was loading.) DOes anyone have any links/code on how to set both the SplashScreenImage to use the .GIF AND how to use the .GIF in a XAML page (from code-behind)?

Silverlight doesn't support GIF files. There are a couple of things you could do. Firstly, you could create the same animation in Blend (as a Storyboard). Or, you could display a WebBrowser control which does render GIF files.
As you mentioned, you can't change the SplashScreen image. It has to be a jpeg and there's no getting around this. What you could do, however, is have your app load your page with your animation in a PopUp. On a separate thread, you can load your main page and then use a dispatcher to push this on to the UI thread. There is an example of how to do this in this blog post.

How to animate image in splash screen for windows phone?

I am working on windows phone app in which I need to animate an object in the splash screen. In the below image you can see that, as soon as the splash screen appears. The ball.png bounces and only after completing the bounce, the app continues into the application. How to do this task?
You have to follow thoses steps to create an animated splashscreen :
You have to create a new Page on your application (called
SplashScreen.xaml) and set it as your 'HomePage'.
You create a storyboard to build your animation.
You subscribe to the Loaded event of the SplashScreen page, and start your
storyboard.
When the storyboard is done (subscribe to the Completed event), you can navigate to your
Homepage.
Hope it helps !
Use Extended Splash Screen and set the animation to the image. For more details visit here.

Get Image painted on Window

I have a windows form Window that is being painted on top of by another process. If I try to copy the window image using PrintWindow or device context copy, only my window below shows up:
Window before it's painted on by another process:
Window after it's painted:
Window I get when I do PrintWindow or BitBlt:
Is it possible to read the window draw from the window directly without sending it the paint argument? Can I read it from the graphics card directly?
DirectX breaks the rules, you cannot make PrintWindow() work. Using Graphics.CopyFromScreen() doesn't work either, it has a critical bug that prevents you from passing the correct CopyPixelOperation value. One that was addressed in Windows 8 by Windows itself, you can't rely on it yet.
You'll need to fallback to BitBlt(). The critical option is CopyPixelOperation.CaptureBlt so that video overlays are included in the copy. You'll find the required code in this answer.
If I am correct you want to copy window that is rendered by some DirectX proccess?
You can do that but you need to understand that you can't copy memory from window directly because winows form doesn't have your image, it only have a placeholder for rendered image.
It is only a ilusion that image is rendered inside form.
What you need to do is to copy memory from graphic card but unfortunately I don't know how to do that.
Most simple idea is to get window screenshot like alt+print screen, remove the border and copy that image to your window.

Dmitry is right.
You can only make a CopyFromScreen as he suggested:
Capture the Screen into a Bitmap
You can modify the source code to create a bitmap large as your window and copy only that part of screen

Is there a workaround for the form dimensions forced to be <= screen dimensions limitation of windows forms applications?

I once wrote an app that could display photographs. I am trying to re-write it in Visual Studio with C# and give it new features. The application I am writing now does use scroll bars to facilitate viewing an over-sized image. The previous app would fill the form area with the image and you could drag and hold the mouse to move it about on the screen. If the image was bigger than the screen you'd simply move it about to view previously hidden areas. By making the form the same size as the image it was very elegant way of dealing with the 'problem' of viewing an image that is bigger than your screen dimensions.
The advantage of this over putting the image inside a statically re-sizable form with scroll-bars was that the image would fill the available screen space, and if the next image in the sequence (it is a browser that allows you to cycle through images) was small, the image app would only take up as much space as the image. You could easily move it to one side. You didn't have to manually resize the form that was displaying it to make room for other applications.
I am unable to implement the same feature in the new app because Visual Studio won't let me dynamically re-size the form to be taller or wider than the screen.
Does anyone know of a plugin or workaround to override this limitation?
I am open to suggestions to achieve the same goal, but I would still like to know if this limitation can be turned off, perhaps with a plugin or in code somehow. Below is a link to a video of the previous incarnation of the app, demonstrating the behavior I want to acheive by being able to set the form size larger than the screen dimensions...
Edit: A demo of the the previous application - and the behavior I want to implement...

I think having a form bigger than the screen is not what you should search for. You can play with the position (top/left) coordination of the image on the form. You can have coordinates with minus values, so you will give the impression to the end user that he browse the image boundaries that's outside of the screen dimension.
Simply, you can create a Form with a PictureBox.
Then change the AutoScroll property of the Form (or the container of the PictureBox, if applicable) to true.
And then change the SizeMode property of the PictureBox to AutoSize.
You should end up with something like this:

Can I use the splashScreenImage to all my app pages?

I'm writing an application for wp7 with several pages, and i want to the splash screen image at the load of every page i have in the app - so the user would figure out he needs to wait a few seconds.
The default splash screen image is fine for me, but i don't know how to do it.
thanks for any help!
You can customize your own splashscreen dont need to use the default
Use the Loading method for the page which should be located on a panel on the left side of Visual Studio's Screen
You can do this by loading the SplashScreen Image on load of every page for some predefined time. And meanwhile other tasks can be done on Background threads (if they are not related to UI).
Also if you want to show a loader to User, you can create a Grid with some Background (semi transparent) and a Progress Bar on it. You can set its Visisbility true before any process which will take time and then hide it after process ends and Application is ready for user..

Render WPF-Window to Bitmap

I've created an WPF based application showing me thumbnails of external windows. As an example i pick up icq, firefox and some other windows, create thumbnails of these and render them onto my WPF based application.
That works fine already and looks like this:
http://img560.imageshack.us/img560/1170/oijoijio.jpg
(Just showing one thumbnail in here, but there will be multiple in future)
The WPF application will also contain some controls to actually select the windows being "thumbnailed" and a few others.
The next step and my actual question is about how i would redirect these content being rendered into a Bitmap instead of the "WPF window" itself.
Is there a way to accomblish that goal? All the windows content (WPF containers and the drawn thumbnails) need to be rendered into a bitmap which i can display in directx window being owned by a game.
I know that it is possible todo that somehow, as a programm called overwolf also uses WPF inside of their application. They actually install device inline detours to hook into the rendering process of the game, where they render their wpf content. I am not sure if they use some kind of bitmap they render in there, or if they directly render the wpf content onto the dx-surface somehow.
Other ideas besides the bitmap based style i plan to go for are welcome aswell!
Thanks for your reading until here, and another big hug for any answer :)
Any WPF Visual object can be rendered into a bitmap using RenderTargetBitmap.
