B4X:

Dim bEx As BitmapExtended
Dim iHeight As Int
Dim iWidth As Int

iHeight = bEx.getHeight(LoadBitmap(File.DirAssets, "sample.png"))
iWidth = bEx.getWidth(LoadBitmap(File.DirAssets, "sample.png"))

You can use the standard Bitmap object as well.

BTW:
Is there already a ready-to-use possibility to get the pixel dimensions without loading the whole file?
Sometimes the files are simply huge...

For JPEGs you can use the JPEG library to do that: Basic4android - Jpeg

Thanks a lot!

Jpeg.LoadJpegSizeOnly will do the trick!
