I am developing Windows Store Apps for Tablet using VS2012. Right now i am creating splash screen for my application. My requirement is the splash screen should be display full screen in my app.
but it is working as Center of the screen. Can any one help regarding this...
The answer is that there is no way to create an official splash screen that is full-screen. A splash screen has to use a 620 x 300 pixel image, where it is a normal splash screen or an extended splash screen. However, you can match the background color around the splash screen to the color of the splash screen image (using the instructions you already found), which makes it appear like a full-screen image, even though much of it is just color.
AFAIK a splash screen has to be centered, but maybe a valid work around would be to create a start page (regular xaml) and have this one displayed as initial screen as soon as the splash screen is gone.
But this would mean that your startup time has to be quite fast.
Maybe it's an option for you.
Open the "package.appxmanifest" manifest file.
The manifest should automatically open in the Microsoft Visual Studio Express 2012 for Windows 8 Manifest Designer.
Open the Application UI tab and scroll down to the Splash Screen
section. If you are still using project defaults, you should see the
"images\splashscreen.png" path in the Splash Screen field. If you
open "package.appxmanifest" in a text editor, you should see
SplashScreen element as a child of the VisualElements element. For
example, the default splash screen markup in the manifest file looks
like this:
XML
{ <SplashScreen Image="images\splashscreen.png" /> }
Change the splash screen image by using the Browse... button and
confirm that the image was added to your Visual Studio project.
Important The splash screen image you choose must be 620 x 300
pixels using a 1x scaling factor.
In the Background Color field of the Splash Screen section, set the
background color to display with your splash screen image. You can
enter either the name of a color or '#' and the hex value of a color.
Setting a background color for your splash screen is optional. If you
do not specify a color, the splash screen background color defaults
to the Tile background color (the color in the Background Color field
of the Tile section in the Application UI tab). If you open
package.appxmanifest in a text editor, the Tile background color is
specified via the BackgroundColor attribute of the VisualElements
element.
my workaround is make a 620x300 splash .png image with alpha background, so its not a full 620x300 image. the image itself is just a 300x300 logo. my suggestion is just make a small center image (your app logo or something else) and make it blend to the background (gradient or alpha)

I know when setting the color for a FontImageSource you can use things like:
Color="#512BD4"
to change the color of the icon, but how do you apply the same logic to the splash screen setting as this:
<MauiSplashScreen Include="Resources\Splash\popup_splash.svg" Color="#512BD4" BaseSize="256,256" />
only seems to set the background color of the screen. The icon defaults to black and there aren't any hints in the designer.
You can try to set the TintColor attribute to your MauiSplashScreen like below:
<MauiSplashScreen Include="Resources\Splash\popup_splash.svg" TintColor="#512BD4"/>
Use an image editor that can edit .svg files, to set the color of the foreground shape(s).
[OPINION] IMHO, there is no option to "set foreground color" because there can be MULTIPLE colors in an .svg.
Also, for cross-platform compatibility, Maui converts the .svg into a .png, when building the app for each platform. That is what gets displayed on the device. This conversion is done without any knowledge of that XAML (that later displays the splash screen image on top of the colored background).
Because Maui runs on multiple platforms, expect to see functionality that is easy to implement on all the platforms, and is in high demand by app developers. [OPINION] Being able to dynamically "colorize" a splash screen while the app starts up is not likely to be a high priority "wish" for many app developers.
The "background color" is different, because that simply fills in behind any transparent areas of the image. Easily done on all platforms that Maui targets.
Summary: I'm having a big problem with layout design in my project... I want to set it up in fullscreen mode, but I can only set it in a specify resolution, because of that, when I click to maximize my program, it goes like image #2... I tried to anchor buttons in "Top,Left,Bottom,Right" but the mess is bigger (image #3).
What I need: I want to make a single layout for a fullscreen mode in any screen resolution...

Image 2 below
Image 3 below
When I use fill mode...
If I understand right and you want everything to stretch when you resize your form then you should dock your tablelayoutpanel (fill) and the same with your buttons.
I am working on Xamarin form cross platform app where I need to change default launch screen image.
I changed launch screen images from Asset catalog then lunch screen but when app is launched image is showing small and centered with background of default xamarin background color.
How do i change that too ?
Did you check LaunchScreen.storyboard file?
https://developer.xamarin.com/guides/ios/application_fundamentals/working_with_images/launch-screens/
Maybe you need to check your image dimensions and change the background color of the launch screen in the Resources/LaunchScreen.storyboard file (Color tag).
If you need your launch screen background color white:
<color key="backgroundColor" red="1" green="1" blue="1" alpha="1" colorSpace="calibratedRGB"/>
If you need your launch screen background color black:
<color key="backgroundColor" red="0" green="0" blue="0" alpha="1" colorSpace="calibratedRGB"/>
I've added a PNG animation (acting like a animated GIF) to an iBook HTML widget using CSS, JavaScript and HTML.
The problem is that there is a maximize button when hovering over the widget in the iBook preview. I want to remove this because it is only supposed to be an animation that plays when entering the page, and I don't want the user to be able to interact with it.
How can I remove this functionality from the widget?
Setting the widget width and height in your info.plist file the same as the width and height in iBooks author prevents opening in full screen when tapping on it.
I don't know if this logic works on Mac or iPhone, but it seems to work on the iPad.
I want to develop a new home screen application for android. I saw the default home screen in my android 2.3.3 device, when ever I swipe the home screen left and right, the background wallpaper also sliding left and right. What is that view? How to get the same effect in an app?
Is it ViewPager? I checked the ViewPager class, but I didn't found any common background image for all views in that.
You probably want to use a canvas with a draw-able, then detect the users swiping and animate it in the background. It is likely that the default android backgrounds are doing the same. You wont be drawing the unseen portions of the view.

I suggest doing their lunar lander tutorial to learn how to use the canvas first.
You will make a canvas the background to your app and then lay your other ui elements on top of it unless you make the ui based inside the canvas.
