Re: [Podofo-users] Get Object from Reference is PdfArray?

[Matthew Brincke]

Hi Tom,




I'm so sorry, I should have double-checked before sending: my_pdf_object
needs to be a pointer, not a reference type, but the rest is correct:

The references in the PdfArray are stored as PdfReference instances, soto get 
to the objects (PdfObject instances) referenced, you need to do
the following (more details in the documentation):

// I assume my_pdf_doc to be of type PdfMemDocument or PdfMemDocument&

// put the following lines instead of your (right-hand side here) array access
PdfReference& font_ref = Arr_descendant_fonts[f];
PdfObject* my_pdf_object = my_pdf_doc.GetObjects().GetObject(font_ref);
// do something with my_pdf_object here, it gets overwritten in the loop
} // this you already have (here your loop body ends)


Best regards,

mabri

I have a PdfArray I have extracted from a Font Object and I want to use each 
Reference in the PdfArray to access the actual
object.  How do I do that.

For example:.

PdfObject my_pdf_object;

if(font_object.HasKey("DescendantFonts"));
{
Arr_descendant_fonts  = 
font_dictionary.GetKey("DescendantFonts")->GetArray();
   }


Arr_descendant_fonts_size = Arr_descendant_fonts.size();

for(int f = 0; f < Arr_descendant_fonts_size; f++)
{
//how do I access each object here? 
  my_pdf_object =  Arr_descendant_fonts[f];   // this doesn't work?

}

Thanks
