// 采用 ExitInterface 设置图片旋转方向
ExifInterface exif;
try {
exif = new ExifInterface(filePath);
int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 0);
Matrix matrix = new Matrix();
if (orientation == 6) {
matrix.postRotate(90);
} else if (orientation == 3) {
matrix.postRotate(180);
} else if (orientation == 8) {
matrix.postRotate(270);
}
scaledBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0,
scaledBitmap.getWidth(), scaledBitmap.getHeight(),
matrix, true);
} catch (IOException e) {
e.printStackTrace();
}
这是在缩放法压缩后 又生成了一个scaledBitmap 但是 目前并没有发现他有什么用处,请指教
