在保持分辨率的同时保存URI图像或转换为位图

Question

所以我已经将我的图像成功传递给URI ...但是我不知道如何保存它或将其转换为位图，同时仍保持分辨率。有什么建议？谢谢。

photoButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // CALL THE PICTURE (this works)

            File t = new File (STORAGE_PATH + "savedAndroid.jpg");
            mURI = Uri.fromFile(t);
            i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mURI);
            startActivityForResult(i,0); //0 is default camera
        }
    });

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    imageView.setImageURI(mURI); //this seems to work...by itself


      //save the image or convert it to a bitmap to use with tesseract...
}

Answer 1

InputStream is = context.getContentResolver().openInputStream(mURI);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, new BitmapFactory.Options());

然后随意使用它。 希望这会有所帮助。
