[poppler] annotations survive in saveas copy AFTER removing them

[Jannick]

Dear All,

 

my code snip below suggests that 'a.pdf' is copied to 'b.pdf' AFTER

removing all annotations of a.pdf. However, b.pdf still contains all 

annotations seen in a.pdf.

 

Am I missing something obvious here?

 

Thanks,

J.

 

// main.cpp:

#include <stdio.h>

#include <stdlib.h>

#include <PDFDoc.h>

#include <GlobalParams.h>

 

 

int main(int argc, char** argv)

{

    const char* f_in = "test_in.pdf";

    const char* f_out= "test_out.pdf";

 

    GooString gf_in(f_in);

    GooString gf_out(f_out);

    globalParams = new GlobalParams();

    PDFDoc * doc = new PDFDoc(&gf_in);

    if ( doc->isOk() )

    {

        int i_pages = doc->getNumPages();

        for ( int i_page = 1; i_page <= i_pages; i_page++ )

        {

            Page * page = doc->getPage(i_page);

            if( page )

            {

                Annots * annots = page->getAnnots();

                int n_annots = annots->getNumAnnots();

                for ( int i_annot = 0; i_annot < n_annots ; i_annot++ )

                    annots->removeAnnot(annots->getAnnot(i_annot));

            }

        }

        doc->saveAs(&gf_out,writeForceRewrite);

        delete doc;

    }

    else

    {

        fprintf(stderr, "error when opening '%s'\n", f_in);

    }

    delete globalParams;

    return 0;

}
