'Image must be resized' 当相机尺寸超过 15Megapixel 时从 phone 捕获图像时出错

Question

嗨 Stack Overflow 团队，

以下是 PhotoEditor Android 应用程序的 java 代码，用于捕获图像并将图像保存在 phone

以下是 MainActivity.java 文件：

package com.example.photoeditor;

  private static final String TAG = "MainActivity";
  private static final int IMAGE_EDITOR_RESULT = 1;

  private ImageView mEditedImageView;

  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mEditedImageView = (ImageView) findViewById(R.id.edited_image_view);

    Bundle extras = getIntent().getExtras();
    if (extras != null) {
      Uri imageUri = Uri.parse(getIntent().getExtras().getString(IMAGE_URI));
      Intent imageEditorIntent = new AdobeImageIntent.Builder(this).setData(imageUri).build();
      startActivityForResult(imageEditorIntent, IMAGE_EDITOR_RESULT);
      finish(); // Comment this out to receive edited image
    }
  }

  // Do something with the edited image
  @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
      switch (requestCode) {

问题是在捕获图像之后，然后在从应用程序编辑照片之后，然后当必须保存图像时，我发现图像没有保存在 phone

当我在 Android Studio 中看到 Logcat 时，我看到了这个警告：

所以只有当 phone 的相机尺寸超过 15Megapixel 时拍摄图像才会出现保存问题。

谁能帮忙提供可能的代码解决方案？

提前致谢

Answer 1

使用此代码调整大小并保存：

Bitmap image = (Bitmap) "your image";
image = Bitmap.createScaledBitmap(photo, 100, 100, false);
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.JPEG, 60, bytes);

File file = new File(Environment.getExternalStorageDirectory()
        + File.separator + "name.jpg");
file.createNewFile();
FileOutputStream fo = new FileOutputStream(file);
fo.write(bytes.toByteArray());
fo.close();

60表示压缩质量：0是最高压缩质量低。 100 是最低压缩最高质量

'Image must be resized' 当相机尺寸超过 15Megapixel 时从 phone 捕获图像时出错

'Image must be resized' error when the image is captured from phone when the camera size is more than 15Megapixel
