Transition from Windows Live Photo Gallery (WLPG) to ACDSee 2021

I'm not sure I quite understand the question but usually the region dimensions are 5-7 decimal places which keeps an accuracy to significantly less than the size of a pixel.  The conversions themselves are very simple mathematical formulas.  In most cases you can convert from MS Regions->IPTC Regions->MWG/ACDSee Regions->MS Regions and end up with the same numbers.

After digesting this thread more carefully, I think that I just need to figure out what region type (MPR / IPTC / MWG) Picasa used when it stored the face tag info in the metadata - and use the associated command with StarGeeks conversion config file.

I attached one sample file. Below is an exiftool excerpt of the region-related data from it. Can you identify which conversion I should be using?

JPEG APP1 (1339 bytes):

  | RegionAppliedToDimensionsW = 2640
  | RegionAppliedToDimensionsH = 1980
  | RegionAppliedToDimensionsUnit = pixel
  | RegionName = Bob Klink
  | RegionType = Face
  | RegionAreaX = 0.307576
  | RegionAreaY = 0.599495
  | RegionAreaW = 0.486364
  | RegionAreaH = 0.777778
  | RegionAreaUnit = normalized
  | RegionName = Patricia Klink
  | RegionType = Face
  | RegionAreaX = 0.767045
  | RegionAreaY = 0.458333
  | RegionAreaW = 0.464394
  | RegionAreaH = 0.878283

Picasa used MWG regions.  Windows photo gallery used Microsoft (MS) regions.  ACDSee uses their own ACDSee regions and can load MWG regions.  AFAIK, there hasn't been a program that will read/write IPTC regions.

ACDSee can also read MWG regions.

Using the convert_regions.config file you can convert freely between IPTC, MWG, and MS regions.  Using the ACDSee config file linked above, you can convert any of those regions into ACDSee regions.

But there's already plenty of deal breakers for me to use it.  Database is set to C:\User\<username>\AppData\Local\ and I can't find a way to change it.   ...  Also adds in a right-click context menu for Windows directories and no apparent way to disable it.   ... Also, a tray icon that is there even when the program isn't running. 

All this can easily be changed, but this is the wrong forum. Ask at https://forum.acdsee.com/forum
