How to use it inside Compose?
I have tried : @Composable fun ComposableCropImageView(position: Int, setCropImageView: (CropImageView) -> Unit, force16_9: Boolean){ // Image Cropper fill the remaining available height AndroidView( factory = { context -> Log.d(TAG, "in factory") val uri = getPhotoUri(position) var anaBitmap = getAnaBitmap(uri) if (isHalfWidth){ anaBitmap = anaBitmap.scale(anaBitmap.width * 2, anaBitmap.height, false) } Log.d(TAG, "HERE") CropImageView(context).apply { layoutParams = ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT ) setImageBitmap(anaBitmap) setOnCropWindowChangedListener { onCropWindowChangedCallback(cropRect) } setCropImageView(this) // Store the instance Log.d(TAG, "end factory") }
},
modifier = Modifier
.fillMaxSize(),
update = {cropImageView ->
Log.d(TAG, "start update")
if (force16_9) {
cropImageView.setAspectRatio(16, 9)
cropImageView.setFixedAspectRatio(true)
sharedViewModel.setCropAspectRatio16x9(true)
}
else {
cropImageView.setFixedAspectRatio(false)
sharedViewModel.setCropAspectRatio16x9(false)
}
Log.d(TAG, "end update")
}
)
}
but adding this Composable to my screen makes a timeout while composition. and then a crash and a tombstone file.
@Franky4242 Did you figure out how to use this in Compose? I can use the launcher. But I don't see the crop button and I'm not sure how to add a button to crop the photo?
`@Composable fun ImageCropLauncher( onCropResult: (Uri?) -> Unit ) { val cropImage = rememberLauncherForActivityResult(CropImageContract()) { result -> if (result.isSuccessful) { onCropResult(result.uriContent) } else { onCropResult(null) } }
Button(onClick = {
val cropOptions = CropImageOptions(
fixAspectRatio = true,
aspectRatioX = 1,
aspectRatioY = 1
)
val options = CropImageContractOptions(
uri = null,
cropImageOptions = cropOptions,
)
cropImage.launch(options)
}) {
Text(text = "select_image")
}
}`
Hello Brian,
I have redeveloped a code with the functions I need for my app in Compose. If you are interested I can share it with you.
Kind regards
Frank
