To rotate an image in android you should look here

Or here

To get a mirror image of your PNG, do this (taken from the link below, from Dalmas's answer)

Matrix matrix = new Matrix(); 
matrix.preScale(-1.0f, 1.0f); 
Bitmap mirroredBitmap = Bitmap.createBitmap(bmp, 0, 0, bmp.width(), bmp.height(),  matrix, false);

To rotate a vector look here

  • Everything is good... but... I think I'll have a little problem with straightforwardness of lines... as You can see border between green and red region is not ideal line... because it is pixels png image... and when I rotate image i'll take line of transperent regions insead of border – user1800819 Nov 15 '12 at 21:13
