HEIC image marked up on iPhone not detected as an HEIF file #418

I tried converting HEIC images to JPG using heif-convert on libheif 1.6.1, installed on Ubuntu 20.04.1 LTS via apt install libheif-example package. Also cloned the recent 1.10.0 version, successfully compiled libheif with jpeg support. Used the provided heif-convert under the examples folder with the same result as below:

When I didn't edit the HEIC image and just directly convert, it runs fine.

But when I did some markup like using opaque boxes to redact information through the iPhone device, then convert with heif-convert on my PC, it fails to detect the marked up image as an "HEIF file".

Please attach an example file so that I can have a look. You could check that the file you got after editing is really an HEIF file. I have seen files with heif suffix that are actually JPEGs.
