MWG face tags/regions written incorrectly

[vernbeau]

There is a defined standard to the structure of MWG face regions.
Roughly like this.
struct RegionInfo
{
struct AppliedToDimensions;
struct RegionList;
}
XnView is writing the AppliedToDimensions outside of the RegionInfo structure

These regions will not be processed correctly by ACDSee, exiftool and others.

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.7.1. Please check and confirm the bug fix here.

The issue is improved, but not resolved.
The order of the mwg face data should be:

RegionAppliedToDimensionsH
RegionAppliedToDimensionsUnit
RegionAppliedToDimensionsW
RegionAreaH
RegionAreaUnit
RegionAreaW
RegionAreaX
RegionAreaY
RegionName
RegionType

The issue is improved, but not resolved.
The order of the mwg face data should be:

I'm not sure that specific order is needed for XMP

See the MWG Regions Tags section: https://exiftool.org/TagNames/MWG.html

Also, ACDSee will not read in the region data unless it is in the order specified.

i'll change the order but for me there is no need to use a specific order
