I need to perform an export of a subset of user created areas to a pdf file keeping their original appearance as much as possible. I've used the FineReader engine VisualComponents example as starting point as it can be used to export to rtf a document which is fully processed by the engine.
I managed to export the full document as pdf but I could always export only the whole file as it was synthesized or part of it removing auto recognized blocks manually. However I need to manually add blocks from scratch, and export a pdf file with only specified blocks.
I set up a simple function which goes from document creation and programmatically add a text block to all pages of a document and went thorugh recognition of blocks but if I try to export the document to a pdf file I get the error "The logical structure of the document is invalid. Please, perform document synthesis". But if I perform a sysnthesis of the document my custom blocks are removed and the full document is exported.
How can I export only the blocks I need?
