Hello,

Is it possible to manipulate the XMP Tags by LeadTools, for example the Rating visualized by Win7 by 0 to 5 stars?

I can't find the XMP tags among the LeadTools comment types:
DICOM File Comments
Exif File Comments
FlashPix File Comments
GIF File Comments
IPTC Comments
JPEG and LEAD File Comments
JPEG 2000 File Comments
PNG File Comments
TIFF File Comments

Best regards,
Plamen

Our RasterTagMetadata takes an integer for the ID in order to allow writing to tags we did not necessarily enumerate. Since XMP tags are written to a tag which contains an XML packet you only need that tag id to write to it, but you will need to ensure that you structure the XML data appropriately.

At this link you can find some tags this site has many more listed so it is a good resource for tags we have not enumerated.

XMP tag is 700 or 0x02BC(in hex). You will probably want to read further into writing XMP tags specifically for generating the XML data to apply here.
