Hello, I posed this question/issue about a year ago or so and there were no responses. Figured I would try again and see if anyone else has experienced a similar issue.
On occasion I come across a PDF that has what Acrobat considers "Hidden Text" Usually the only way to view this Hidden text is to perform "Examine Document" in Acrobat which it then gives you the ability to remove or view that hidden text. I have tried conversion with a variety of parameters (flatten, poly2bitmap, etc) with the current version of PDF2SWF and past versions on Windows and this "hidden text" always appear in the SWF output from pdf2swf. Acrobat and other PDF Readers seem to honor this hidden text and not display it when opened, but PDF2SWF seems to always show it....any thoughts? Does pdf2swf understand the concept of what PDF flags as "hidden"? If a sample would be helpful, I will see I can locate one that exhibits the behavior. While the Examine Document > Remove function in Acrobat works to get rid of the text altogether before converting to SWF, many of the PDFs are provided from various Users who would not understand that concept or have the ability to access Acrobat Pro to perform such a process, so if PDF2SWF can accommodate this during the conversion process, that would awesome. Looking at some of the past GIT comments, I saw an entry for something stating "remove invisible characters" https://github.com/rpedroso/swftools/blob/3575ceae924318b7d9d518d900eb7742a9db6b10/lib/filters/remove_invisible_characters.c But was not sure if that applies to this "hidden text" element or if this update applies to the Windows version of PDF2SWF. Thanks for any direction you can point me in Cheers -- JL
