私は、カメラで画像をキャプチャできるアプリを作成しています。クロップされた画像がtess-twoで機能しない
イメージをトリミングするオプションを追加するまで、コードは正常に機能します。画像をトリミングした後にエラーがライン上で発生し
tessbaseAPI.setImage(bitmap)
ログは以下
Failed to read bitmap
は画像
private void performCrop() {
// take care of exceptions
try {
Log.v(TAG, "Inside try of performCrop");
// call the standard crop action intent (the user device may not
// support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.setDataAndType(picUri, "image/*");
// set crop properties
cropIntent.putExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.putExtra("aspectX", 2);
cropIntent.putExtra("aspectY", 1);
// indicate output X and Y
cropIntent.putExtra("outputX", 256);
cropIntent.putExtra("outputY", 256);
// retrieve data on return
cropIntent.putExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
Log.v(TAG, "Going to onActivityResult now");
startActivityForResult(cropIntent, CROP_PIC);
}
// respond to users whose devices do not support the crop action
catch (ActivityNotFoundException anfe) {
Toast toast = Toast
.makeText(this, "This device doesn't support the crop action!", Toast.LENGTH_SHORT);
toast.show();
}
}
を切り出すためと
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
if (requestCode == REQUEST_IMAGE_CAPTURE) {
Log.v(TAG, "Request Code is REQUEST_IMAGE_CAPTURE");
picUri = data.getData();
performCrop();
} else if (requestCode == CROP_PIC) {
Log.v(TAG, "Request Code is CROP_PIC");
Bundle extras = data.getExtras();
Bitmap bitmap = extras.getParcelable("data");
TextView res = (TextView) findViewById(R.id.hello);
//imageView.setImageBitmap(imageBitmap);
//Image image = ImageIO.read(imageFile);
//BufferedImage buffimg = (BufferedImage) image;
//BufferedImage img = ImageHelper.convertImageToGrayscale(buffimg);
//ITesseract instance = new Tesseract(); // JNA Interface Mapping
//ITesseract instance = new Tesseract1(); // JNA Direct Mapping
//TessDataManager.initTessTrainedData(context);
if (isStoragePermissionGranted() == true) {
TessBaseAPI tessBaseAPI = new TessBaseAPI();
String path = Environment.getExternalStorageDirectory() + "/";
//String path = "/mnt/sdcard/";
tessBaseAPI.setDebug(true);
tessBaseAPI.init(path, "eng");
tessBaseAPI.setImage(bitmap);
String text = tessBaseAPI.getUTF8Text();
tessBaseAPI.end();
res.setText(text);
}
}} else {
TextView res = (TextView) findViewById(R.id.hello);
res.setText("Well damn");
}
}
}

実行するための私のコードであると言います
Aからのラインog
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=2, result=-1, data=Intent { act=inline-data (has extras) }} to activity {com.example.abc.snaptravel/com.example.abc.snaptravel.MainActivity}: java.lang.RuntimeException: Failed to read bitmap
私は助けていただきありがとうございます。ありがとうございました!
