Rating property of a jpeg image

Question

0.00/5 (No votes)

See more: (untagged)

I have a Jpeg image generated and rated using Paint Shop Pro 2019. Windows properties of the image show the Stars rating. But when I try to get the rating in Vb.Net like:

Dim propRating As PropertyItem
propRating = myImage.GetPropertyItem(18246)

the property is not found. Evidently it is not in the Exif, but where?

So please, I kindly ask: where in the image is the rating that Windows display in the properties? How can I get it?
I'm not interested in putting the rating in the Exif, I wish only grab the rating that Windows displays.

Thank you.
Paolo

PS 18246 is the decimal Id of the property.

What I have tried:

I've tried this code:

Dim propRating As PropertyItem
propRating = myImage.GetPropertyItem(18246)

Note: this code works fine if I impose the rating directly in the Windows properties.

Could PSP be setting the RatingPercent property instead? (18249)

No, I checked this too.
It seems that PSP stores the rating outside the Exif. Maybe I have to search something like a XMP format?
But in the meanwhile I have found that exists a Windows.Storage.FileProperties that contains a ImageProperties.Rating Property.
Surely PSP stores rating there and I have to reach that place.

The rating is stored in the XMP block. This is a text block and it contains a statement like:

<xmp:rating>3</xmp:Rating>

I have written a library, that can only remove the XMP block. The removal is done, when you save the EXIF data of the image file using the method "Save" and passing the option parameter "ExifSaveOptions.RemoveAdobeInfoBlock". But you can debug the Save method in order to see, how the XMP block is embedded into the JPEG file. And then you can write a method which reads the XMP block instead of removing it.
