i created an image with my own iPhone app. The image is in .heif format and it contains the depth map. (i know this because the Photos app recognizes it) I now downloaded and installed imagemagick. and ran the following command:
magick identify -verbose orginal.HEIC
This shows me only three channels (Channel 0, Channel 1, Channel 2). I guess these are the rgb colors of the image.
How can I access the depth data of this image?
