Given a bitmap i want to turn it to GrayScale. I found this solution but now that my phone got updated in Android 10 i get an IllegalArgumentException: Software rendering doesn't support hardware bitmaps exception.
fun getGrayScale(src: Bitmap): Bitmap {
//Custom color matrix to convert to GrayScale
val matrix = floatArrayOf(
0.3f,
0.59f,
0.11f,
0f,
0f,
0.3f,
0.59f,
0.11f,
0f,
0f,
0.3f,
0.59f,
0.11f,
0f,
0f,
0f,
0f,
0f,
1f,
0f
)
val dest = Bitmap.createBitmap(src.width, src.height, Bitmap.Config.RGB_565)
val canvas = Canvas(dest)
val paint = Paint()
val filter = ColorMatrixColorFilter(matrix)
paint.colorFilter = filter
canvas.drawBitmap(src, 0.toFloat(), 0.toFloat(), paint)
return dest
}
So now i have 2 questions.
1) What should i change so that can work again
2) Can i do this with Glide libray so i dont need to write any code?
