How are parasites represented in Script-Fu?

Hi

Currently, what type of data should be used to enter a parasite as a parameter within those Script-fu procedures that handle such an object? By chance, can you give me any examples?

In order to figure it out, I have done several tests through the TinyScheme Console, from time to time using lists, vectors or strings, but none of them seems to fit.

Thanks in advance.

AFAIK, only strings are supported and are passed in as a list. First parameter is the parasite name and the third is the string value. Not sure what the seconf parameter is but I always use the number 1:

(gimp-parasite-attach (list "parasite-name" 1 "parasite value"))

The second parameter is the persistence/UNDOability flag. I covered the possible values in the following thread:

For images and drawables, I would assume "persistence" may also be dependent upon the file being saved in XCF format (perhaps other formats permit parasite data to be attached as EXIF data but I wouldn't count on it). For vectors/paths, there would be the additional issue of whether the path itself was recoverable from the file.
