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/

首先使用回報的影像尺寸重現 tns resources generate splashes image.png，並檢查產生的 Android xxxhdpi 資源。追蹤 splash 產生的 CLI 進入點，以確定輸出尺寸的計算方式。當產生的 splash 影像具有受支援平台所預期的尺寸時，即表示完成。
