Hello there,
I wrote a small code based on the image extractor, it doesn't make much
sense but it reproduces the bug.
(my code is too long and specific).
I'd be happy to supply a small input file (how? moderator didn't like my
attachment (19K pdf file))
#ifdef USE_PODOFO
#include <podofo/podofo.h>
using namespace PoDoFo;
void DrawToPdf ()
{
const char* inname = "input.pdf"; //change to full path
PdfDocument indoc( inname ); // <----- crash
TCIVecObjects it = indoc.GetObjects().begin();
PdfObject* pObj = NULL;
while( it != indoc.GetObjects().end() )
{
if( (*it)->IsDictionary() )
{
pObj = (*it)->GetDictionary().GetKey( PdfName::KeyType );
if( pObj && pObj->IsName() && ( pObj->GetName().GetName() ==
"XObject" ) )
{
pObj = (*it)->GetDictionary().GetKey(
PdfName::KeySubtype );
if( pObj && pObj->IsName() && (
pObj->GetName().GetName() == "Image" ) )
{
PdfMemStream* stream =
dynamic_cast<PdfMemStream*>((*it)->GetStream());
stream->Uncompress();
//.......write the file
const char* fname =
"output.pdf"; //change to full path
PdfStreamedDocument document(
fname );
//image Is 1x1 Inch and of 72
dpi
PdfRect rSize(0, 0, 72, 72);
PdfPage* pPage =
document.CreatePage(rSize);
if( !pPage )
{
PODOFO_RAISE_ERROR(
ePdfError_InvalidHandle );
}
PdfPainter painter;
painter.SetPage( pPage );
PdfMemoryInputStream pStream
(stream->Get(), stream->GetLength());
PdfImage pImage(&document);
pImage.SetImageData (72, 72, 8,
&pStream);
painter.DrawImage (0, 0,
&pImage, 1.0, 1.0);
painter.FinishPage();
document.Close();
//.......
break;
}
}
}
++it;
}
}
#endif

Some sample code to trigger the issue and a backtrace would be useful.
