OK, have several questions about tags (and/or comments).

In Windows Explorer, I am able to tag pictures rather easily. What type of tags are the tags that windows explorer writes? Looking at a windows explorer tagged jpg in a hex editor, I see the following (among other things)...

<rdf:Bag xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<rdf:li>pizza</rdf:li>
<rdf:li>sausage</rdf:li>
<rdf:li>pepperoni</rdf:li>
</rdf:Bag>

What type of tags are these? Am I able to read and write these types of tags with leadtools? Are these IPTC comments?

Thanks. Any help would be greatly appreciated.

Hello,

Is this text stored inside the JPEG image? If yes, it might be stored as JPEG tags or comments. In that case, I can investigate further if you send me a sample JPEG file with such comments.

If the text is not stored in the JPEG image itself, LEADTOOLS will not be able to read it or modify it.

Thanks,
