Text Recognition not working in camera rotate:

[FrancisRR]

Photo captured in landscape mode that time recognizer not provided any output(actually text recognizer only working in camera zero angle remaining three angle not working 90,180,270) but portrait mode it's working fine how to solve this issue. please provide the solution in as soon as possible.

I mention my complete code on below

private fun callGallery() {
val intent = Intent()
intent.type = "image/*"
intent.action = Intent.ACTION_GET_CONTENT
startActivityForResult(
Intent.createChooser(intent, "Select gallery"),
AppConstant.GALLERY_REQUEST_CODE
)
}

private fun callCamera() {
    val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
    if (intent.resolveActivity(packageManager) != null) {
        val content = ContentValues()
        content.put(MediaStore.Images.Media.TITLE, "New pictures")
        content.put(MediaStore.Images.Media.DESCRIPTION, "From camera")
        uri = contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, content)
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri)
        startActivityForResult(intent, AppConstant.CAMERA_REQUEST_CODE)
    } else {
        UiUtils.showErrorLog(TAG, "Camera not available")
    }

}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == AppConstant.GALLERY_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        uri = data!!.data
        imageFromPath(this, uri!!)
        ivActualIcon.setImageURI(uri)
    } else if (requestCode == AppConstant.CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        imageFromPath(this, uri!!)
        ivActualIcon.setImageURI(uri)
    } else {
        UiUtils.showErrorLog(TAG, "result empty")
    }
}

private fun imageFromPath(context: Context, uri: Uri) {
    // [START image_from_path]
    val image: InputImage
    try {
        image = InputImage.fromFilePath(context, uri)
        recognizeText(image)
    } catch (e: IOException) {
        e.printStackTrace()
    }
}



private fun recognizeText(image: InputImage) {
    val recognizer = TextRecognition.getClient()
    val result = recognizer.process(image)
        .addOnSuccessListener { visionText: Text ->
            processTextBlock(visionText)
            UiUtils.showErrorLog(TAG, "Success")
        }
        .addOnFailureListener { e ->
            UiUtils.showErrorLog(TAG, "${e.message}")
        }
}

private fun processTextBlock(result: Text) {
    val resultText = result.text
    var lineText: String = ""
    for (block in result.textBlocks) {
        val blockText = block.text
        UiUtils.showErrorLog("Block text", "$blockText")
        for (line in block.lines) {
            lineText = lineText + "\n" + line.text
            UiUtils.showErrorLog("Line text", "$lineText")
        }
    }

}

From the code snippet, you are using InputImage.fromFilePath(context, uri) to read the image. For this API, ML Kit uses the file exif tag to read the image orientation. See here: https://android-developers.googleblog.com/2016/12/introducing-the-exifinterface-support-library.html

If the exif information is missed in the file, the API assume the image is unrotated. If InputImage.fromFilePath(context, uri) does not work for you, you could use ``InputImage.fromBitmap()` here.

Basically, read the Uri file as a bitmap before sending to InputImage. With this API, you could provide the orientation information.
