InputImage.fromMediaImage ignores cropRect

[ivan200]

I'm trying to use simplest qr scanning image analyzer.
And I am trying to scan not the entire area of the screen, but only the center bounded by the frame.
In this example, I set the crop rect for MediaImage, which will be converted to the InputImage and then passed to the scanner.
but scanner still scan entire area

override fun analyze(imageProxy: ImageProxy) {
    val mediaImage = imageProxy.image
    if (mediaImage != null) {
        val cropSize = (min(mediaImage.width, mediaImage.height) * 0.6f).toInt()
        val cropRect = Rect(mediaImage.width / 2 - cropSize / 2, mediaImage.height / 2 - cropSize / 2,
            mediaImage.width / 2 + cropSize / 2, mediaImage.height / 2 + cropSize / 2)

        //here i set crop rect
        mediaImage.cropRect = cropRect
        val image = InputImage.fromMediaImage(mediaImage, imageProxy.imageInfo.rotationDegrees)

        //but here scanner wil process whole image instead of small area
        pendingTask = scanner.process(image)
            .addOnSuccessListener { barcodes ->
                //do something
            }
            .addOnCompleteListener {
                imageProxy.close()
            }
    }
}

Hi, this field is not supported by MLKit currently. We are working on supporting it in future releases.

Is there any progress or an alternative issue that we can subscribe to?

Currently UseCaseGroup is pretty much useless since the Analyzer does not use the cropRect of input images. Manually cropping images seems to be pretty messy.

Looking forwards for this feature!

@cs-googler is this feature still in your backlog? Will this available in the future releases?
