如何简单地改变Android 4.2.2上图片的宽高比？从1920x1080到1920x1280。背景：在我的三星Galaxy S4迷你上，我可以使用本机相机应用程序拍照，这给出了正常的结果。我有一个遥控器，需要它的特殊相机应用程序（"Snap Remote" ），这个应用程序的输出符合错误的宽高比。
How can I simply change the aspect ratio of pictures on Android 4.2.2? Say from 1920x1080 to 1920x1280.
Background: On my Samsung Galaxy S4 mini, I can take pictures using the native camera app and this gives normal results. I have a remote that needs its special camera app ("Snap remote"), and the output of this app comes in the wrong aspect ratio.
I wrote the developers but they haven't replied or fixed it.
This guy works great for me on a Samsung 8.4" pro tab:
Has a long list of pre-set sizes and a select-your-own-size option, which like photoshop allows you to choose whether you want to maintain the aspect ratio or not. You can choose file type and quality as well when saving.
