support hevc tile encode and decode

Hi,

I'm looking for a way to mux heif/heic using HEVC tiles or slices (not heic tile). I notice there are some conditional expressions to deal with item type equal to 'hvt1’ while reading heic. But I want to know how to write heic using hevc tile or slice.

In fact, I try to write other boxes according to ISO/IEC 23008-12:2017. I store the slice item using 'hvt1' instead of 'hvc1', and I add the reference of type 'dpnd' to identify the HEVC tile item as the document do. But only half of the image is shown. And I don't know how to fix it. Is there any good suggestions?

Thanks, Chalice
