    hello,

    I was wondering wether it is possible to add invisible text content behind an image in a pdf document. the text should be searchable / exractable.

    thanks in advance, kabookie

      i think the best option to add invisible (searchable / extractable) text to a document is to simple use text rendering mode "3" for adding text. You can do this using "CSCreator.textSetRenderingMode".

      Adding "real" text behind an image should be possible, but why bother? It is at least less performant.
