Problem import page

[balsamic-r]

Hello i'm having problems with ImportPage

The code

 documents := [...]string{"146654.pdf", "141368.pdf", "146654.pdf"}
 pdf := gofpdf.New("P", "mm", "A4", "")

	

 for _, document := range documents {
  pdf.AddPage()
  gofpdi.UseImportedTemplate(pdf, gofpdi.ImportPage(pdf, document, 1, "/MediaBox"), 0, 0, 210, 297)
  
}

 err = pdf.OutputFileAndClose("example.pdf")
  if err != nil {
     panic(err)
  }	

the result is a 3-page PDF but each page is the first page of document "146654.pdf"

Sorry for my English

I don't see where articolo is defined. Please provide a full snippet of code that I can compile and run as well as the 3 PDFs in question.

Same problem when importing 2 pdf from 2 different streams.
I have tried with a single importer for both streams or with 2 different importers, inside the same target pdf.

Seems in the case of streams the PdfReader created in NewPdfReaderFromStream does not have a sourceFile set, then the hashes generated by shaOfInt() are the same for all objects of all documents, thus the last one imported wins.

I could make it work either with :
parser := &PdfReader{f: rs, nBytes: length, sourceFile: fmt.Sprintf("%p", rs)} in NewPdfReaderFromStream(), but this assumes rs is a pointer
or with :
hasher.Write([]byte(fmt.Sprintf("%s-%s-%s", this.tpl_id_offset, i, this.r.sourceFile))) in shaToInt()

@wdrai possible paste code you mentioned above, sorry, i didn't fint it but

func (this *PdfWriter) shaOfInt(i int) string { hasher := sha1.New() hasher.Write([]byte(fmt.Sprintf("%s-%s-%s", this.tpl_id_offset, i, this.r.sourceFile))) sha := hex.EncodeToString(hasher.Sum(nil)) return sha }

but didn't help

@Zer0-Day this has been fixed in gofpdi v1.0.13
