Scale & rotate Bitmap using Matrix in Android

Question

I\'m trying to scale and rotate in single operation before creting the final bitmap but the preRotate, postConcat doesn\'t seem to work.

Bitmap bmp = ... ori         


        

Answer 1

Matrix rotateMatrix = new Matrix();
rotateMatrix.postRotate(rotation);
rotatedBitmap = Bitmap.createBitmap(loadedImage, 0, 0,loadedImage.getWidth(), loadedImage.getHeight(),rotateMatrix, false);
