A few questions:

1. How to determine the tag name from the id.
2. How to determine the string representation of the tag value. (e.g. Rational, URational).

I have developed a program under Leadtools 13.
The Lead control has a function ReadComment which returns the value for a IPTC comment.
The return value is always a string.
Now under Leadtools 17 the values may be from type Ascii, Rational etc.
My questions:
1. How determine a collection of all IPTC (Name, Value as string).
2. How convert the value into string (for each data type (e.g. URational) ).

You can use the RasterCodecs.ReadComment Method to get the comment field from a file and the RasterCommentMetadata.GetDataType Method which gets the RasterCommentMetadataDataType of the specified RasterCommentMetadataType.

You can check these methods' help topics in the .NET help file for more information and a sample code.
