Changing your Game Thumbnail on Windows Phone
The thumbnails are the graphic elements that appear alongside the name of your game in the lists where each can be selected to run on the Windows Phone device.
A Windows Phone project requires the specification of two thumbnails, defined in the XNA Game Studio Properties Page as the Game Thumbnail and the Tile.
The following table summarizes the usage and requirements of each thumbnail used in a Windows Phone project:
62x62 pixels or
The (smaller) icon displayed when listed in the Application List on the Windows Phone device or
The (larger) icon displayed when listed in the Games Hub on the Windows Phone device.
|Tile||Background.png||173x173||The icon used when the game is "pinned" to the Windows Phone Start menu.|
Game Thumbnail Dimensions
The game's genre setting determines which list your deployed game appears in, either the Application List or the Games Hub. For more information on this, see the topic Configuring the Genre of Your Windows Phone Game.
As the table above shows, the optimal dimensions of the thumbnail differ, depending on which list it is to appear.
In either list, if the dimensions of the thumbnail do not match the optimal dimensions, it will be scaled so that its largest dimension matches the optimal dimension, with an appropriate aspect ratio. However, this scaling may produce an unattractive result, so it is recommended that your thumbnail's size match the optimal dimensions.
The Game Thumbnail file must be in .png format.
The Tile thumbnail can also appear in the Start menu once the application or game has been "pinned" there. This occurs when the user clicks and holds on the thumbnail in Games Hub or the Application List and selects “pin to start.”
The dimensions of the Tile thumbnail are always 173 x 173 pixels, and the file must be in .png format.
Changing the Thumbnail Files
The template for a new Windows Phone project automatically creates the files GameThumbnail.png (for the Game Thumbnail) and Background.png (for the Tile thumbnail).
The project template for Windows Phone defaults to the genre type App.Normal, which will place the deployed project in the Application List. The dimensions of the created GameThumbnail.png file will be optimal for that usage (62x62 pixels).
To change the thumbnails, you can overwrite the default files created by the template with files having the same name. Or you can change the properties to use different thumbnail files.
To change the thumbnail files
- Delete the default GameThumbnail.png and Background.png files from the Windows Phone project.
- Add the new thumbnail files you have created to the Windows Phone project.
- Double-click the Properties item in Solution Explorer and select the XNA Game Studio Properties page in the resulting Properties Designer.
- From the Game Thumbnail drop-down list, select the .png file you wish to use for the thumbnail.
- From the Tile Image drop-down list, select the .png file you wish to display when the the game appears in the Start menu.
Since the thumbnails for Games Hub and the Start menu require the same dimensions, you can assign the same thumbnail file for both when the genre type is set to App.Games. For example, both the Game Thumbnail and the Tile Image properties can be set to the default Background.png file.
