image - Windows Phone 8 Xaml image resolution

Question

with the 3 windows phone resolution :

• 480 × 800
• 768 × 1280
• 720 × 1280

that are scaled to :

• 480 × 800
• 480 × 800
• 480 × 853

What is the size for the image that I should use (admit I want to have a full screen image and that I ignore the 720p resolution) ?

480x800 and use <Image Source="..." />

768x1280 and use <Image Source="..." Width="480" Height="800" />

Using a 768x1280 image and scalling it to 480x800 is usefull ?

Thanks for your answer Best regard

Answer 1

使用 768x1280 图像并将其缩放到 480x800 有用吗？

是的。您应该始终选择 WXGA 分辨率的图像，并让操作系统为您缩小图像。（比例大约为 1.6）。

此外，如果可以避免的话，永远不要在 XAML 中指定静态宽度/高度。
