Bitmap convert(Bitmap a, int width, int height){int w = a.getWidth();int h = a.getHeight();Bitmap newb = Bitmap.createBitmap(ww, wh, Config.ARGB_8888);// 创建一个新的和SRC长度宽度一样的位图Canvas cv = new Canvas(newb);Matrix m = new Matrix();m.postScale(1, -1); //…
本篇文章是对使用Matrix对bitmap的旋转与镜像水平垂直翻转进行了详细的分析介绍,需要的朋友参考下 Bitmap convert(Bitmap a, int width, int height){int w = a.getWidth();int h = a.getHeight();Bitmap newb = Bitmap.createBitmap(ww, wh, Config.ARGB_8888);// 创建一个新的和SRC长度宽度一样的位图Canvas cv = new Canvas(…
Bitmap convert(Bitmap a, int width, int height) { int w = a.getWidth(); int h = a.getHeight(); Bitmap newb = Bitmap.createBitmap(ww, wh, Config.ARGB_8888);// 创建一个新的和SRC长度宽度一样的位图 Canvas cv = new Canvas(newb); Matrix m = new Matrix(); //翻转是90° 下面三个选其中之…
