【问题描述】：

我正在使用 Aviary 在我的 android 应用程序中编辑图像，但我发现返回的图像比原始图像小。

例如，我将一张 2560x1920 的大图传到 aviary，但返回的图像是 480x640。

这是我的代码：

private void startFeather(Intent data) {
    File file = getBitmapFromResult(data);

    BitmapInfo bitmap = Helper.getBitmap(file, App.screenWidth, 0);
    toastLong("raw photo: " + bitmap.getWidth() + "x" + bitmap.getHeight());

    Uri uri = Uri.fromFile(file);

    this.featherOutputFile = new File(App.Path.tempDir(), "111" + ".jpg");

    // Create the intent needed to start feather
    Intent newIntent = new Intent(self, FeatherActivity.class);

    // set the source image uri
    newIntent.setData(uri);

    // pass the required api key ( http://developers.aviary.com/ )
    String API_KEY = "aaabbbccc";

    newIntent.putExtra("API_KEY", API_KEY);

    // pass the uri of the destination image file (optional)
    // This will be the same uri you will receive in the onActivityResult
    newIntent.putExtra("output", Uri.parse("file://" + featherOutputFile.getAbsolutePath()));

    // format of the destination image (optional)
    newIntent.putExtra("output-format", Bitmap.CompressFormat.JPEG.name());

    // output format quality (optional)
    newIntent.putExtra("output-quality", 100);

    // you can force feather to display only a certain tools
    // newIntent.putExtra( "tools-list", new String[]{"ADJUST", "BRIGHTNESS" } );

    // enable fast rendering preview
    newIntent.putExtra("effect-enable-fast-preview", true);

    // limit the image size
    // You can pass the current display size as max image size because after
    // the execution of Aviary you can save the HI-RES image so you don't need a big
    // image for the preview
    newIntent.putExtra("max-image-size", App.screenWidth);
    newIntent.putExtra("effect-enable-external-pack", false);
    newIntent.putExtra("stickers-enable-external-pack", false);
    newIntent.putExtra("effect-enable-borders", false);

    // HI-RES
    // You need to generate a new session id key to pass to Aviary feather
    // this is the key used to operate with the hi-res image ( and must be unique for every new instance of Feather )
    // The session-id key must be 64 char length
    String mSessionId = StringUtils.getSha256(System.currentTimeMillis() + API_KEY);
    newIntent.putExtra("output-hires-session-id", mSessionId);

    // you want to hide the exit alert dialog shown when back is pressed
    // without saving image first
    // newIntent.putExtra( "hide-exit-unsave-confirmation", true );

    // ..and start feather
    startActivityForResult(newIntent, INTENT_FEATHER);
}

我有什么想念的吗？

【问题讨论】：

您是否使用了高分辨率输出？否则只返回较小的预览，其大小取决于设备的内存。
我能帮你吗？但是你需要使用其他的库。
@Freewind 很抱歉，因为我在问这个问题，因为即使两年后这个问题也没有得到任何答案。你有没有得到任何解决方案。我现在面临同样的问题

【解决方案1】：

终于找到解决办法了。在 Aviary android 示例应用程序中提到了它

final DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics( metrics );
        int max_size = Math.max( metrics.widthPixels, metrics.heightPixels );
        max_size = (int) ( (float) max_size / 1.2f );
        newIntent.putExtra( Constants.EXTRA_MAX_IMAGE_SIZE, max_size );
