如何调整我的代码以获取所需的屏幕截图，同时裁剪顶部和底部？

Question

我有以下 Kotlin 代码，它截取了显示区域的屏幕截图：

fun screenShot() {
    val bitmap = Bitmap.createBitmap(wholeScreen.width,wholeScreen.height-gameDimensions.bottomNavigationViewHeight, Bitmap.Config.ARGB_8888)
    val croppedBitmap = Bitmap.createBitmap(bitmap, 0, gameDimensions.verticalInc.toInt(), bitmap.width, (bitmap.height - gameDimensions.verticalInc).toInt())
    val canvas = Canvas(croppedBitmap)
    wholeScreen.draw(canvas)
    val out = ByteArrayOutputStream()
    croppedBitmap.compress(Bitmap.CompressFormat.PNG, 100, out)
    val screenShot = ColourBoardScreenShot(BitmapDrawable(theUi.resources, croppedBitmap))
    bundle.putParcelable ("screenshot", screenShot)
}
