Describe the bug

When running tns resources generate splashes image.png the android splash screens are very small.
I tried with different sizes of input image, all corresponding to a scale up of xxxhdpi. Still, very small. Tried with a square image instead of 1920x1080, same result.

To Reproduce

• Create an image, 1920x1080, or anything bigger/smaller
• tns resources generate splashes image.png
• Go to the Android's xxxhdpi resources folder.
• The image is like 640px

Expected behavior
Images the right size, but I'm really not sure what it's expecting as an input. Bigger files with special names for IOS?
I ended up using http://images.nativescript.rocks/

首先使用报告的图像尺寸重现 tns resources generate splashes image.png，并检查生成的 Android xxxhdpi 资源。跟踪 splash 生成的 CLI 入口点，以确定输出尺寸的计算方式。当生成的 splash 图像具有受支持平台所预期的尺寸时，即表示完成。
