Hello,
Just ignore the "Deman loading..." stuff (I commented out that code in
my own copy of podofo).
I had the same problem a few months ago. I needed to fill out a form
and have my changes "visible" inside Adobe Reader. A few helpful
individuals on this list provided me with the information that I needed. I
ended up implementing this function, which I call before filling in the
individual form text fields. I won't claim that my solution is the "correct
solution", but it works for me.
// See section 12.7.3.3 (page 434) of ISO-32000-1:2008.
// Need to construct an appearance stream for each form field,
// or configure document to generated one dynamically.
// See section 12.7.4.3 (page 444) of ISO-32000-1:2008.
// Shows a correct "Appearance Stream" for a text field.
// We can always directly hack the dictionary thuslu:
// PdfAnnotation::GetObject()->GetDictionary()
static void HackPdfFormDocument (PdfDocument &doc)
{
//
http://www.mail-archive.com/[email protected]/msg01155.html
// Stolen from PdfAcroForm::Init()
// doc.GetAcroForm()->Init
(PdfAcroForm::ePdfAcroFormDefaultAppearance_BlackText12pt);
PdfObject *pObj = doc.GetAcroForm()->GetObject();
pObj->GetDictionary().AddKey (PdfName ("NeedAppearances"),
PdfVariant (true));
if (!pObj->GetDictionary().HasKey("DA"))
{
PdfFont *pFont = doc.CreateFont ("Arial");
PdfObject *pResource = NULL;
PdfObject *pFontDict = NULL;
// Create "DR" key.
if (!pObj->GetDictionary().HasKey (PdfName ("DR")))
{
pObj->GetDictionary().AddKey (PdfName ("DR"),
PdfDictionary());
}
pResource = pObj->GetDictionary().GetKey( PdfName("DR") );
if (!pResource->GetDictionary().HasKey( PdfName ("Font")))
{
pResource->GetDictionary().AddKey (PdfName ("Font"),
PdfDictionary());
}
pFontDict = pResource->GetDictionary().GetKey(
PdfName("Font") );
pFontDict->GetDictionary().AddKey( pFont->GetIdentifier(),
pFont->GetObject()->Reference() );
// Create "DA" key.
std::ostringstream oss;
PdfLocaleImbue (oss);
oss << "0 0 0 rg /" << pFont->GetIdentifier().GetName() << "
12 Tf";
pObj->GetDictionary().AddKey( PdfName("DA"), PdfString(
oss.str() ) );
}
}
