Android Glide transform旋转rotate圆图CircleCrop，Kotlin

import android.graphics.Bitmap

    private val TAG = "fly/${this::class.simpleName}"

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val imageView = findViewById<ImageView>(R.id.image)

        GlideApp.with(this)
            .load(R.mipmap.pic2)
            .transform(RotateCircleCrop())
            .override(500, 500)
            .into(imageView)
    }

    inner class RotateCircleCrop : CircleCrop() {
        override fun transform(
            pool: BitmapPool,
            toTransform: Bitmap,
            outWidth: Int,
            outHeight: Int
        ): Bitmap {
            Log.d(TAG, "$outWidth $outHeight ${toTransform.byteCount}")

            //先变换成圆形图。
            val bmp = TransformationUtils.circleCrop(pool, toTransform, outWidth, outHeight)

            //再逆向旋转30度。
            return TransformationUtils.rotateImage(bmp, -30)
        }
    }
}

正常的摆放：

逆向旋转30度：
