如何在 kotlin 中将 BitmapDrawable 或 Bitmap 转换为 ImageBitmap

Question

我需要更改Bitmap?或BitmapDrawable显示ImageBitmap它，coil 这是我的代码

val bitmap = BlurhashDecoder.decode(blurhash, 4, 3)
Image(
    bitmap = bitmap as ImageBitmap,
    modifier = modifier,
    contentScale = ContentScale.Crop,
    contentDescription = ""
)

当我运行它时，我收到此错误

java.lang.ClassCastException: android.graphics.Bitmap cannot be cast to androidx.compose.ui.graphics.ImageBitmap

用于bitmap.asImageBitmap()将 a 转换bitmap为ImageBitmap
