Hi!
i need to extract text from pdf, so i try to use podofo.
1) i build podofo.dll on win32 xp - visual studio express 10
2) i made pdf file "helloworld.pdf" with application example for the PoDoFo
PDF library
3) that file as i can see - look good, so, i think dll was build correctly
4) i try with podofotxtextract tool extract text from "helloworld.pdf", but
in that function:
void TextExtractor::AddTextElement( double dCurPosX, double dCurPosY,
PdfFont* pCurFont, const PdfString & rString )
{
if( !pCurFont )
{
fprintf( stderr, "WARNING: Found text but do not have a current
font: %s\n", rString.GetString() );
return;
}
if( !pCurFont->GetEncoding() )
{
fprintf( stderr, "WARNING: Found text but do not have a current
encoding: %s\n", rString.GetString() );
return;
}
// For now just write to console
PdfString unicode = pCurFont->GetEncoding()->ConvertToUnicode( rString,
pCurFont );
const char * pszData = unicode.GetStringUtf8().c_str();
while( *pszData ) {
//printf("%02x", static_cast<unsigned char>(*pszData) );
++pszData;
}
printf("(%.3f,%.3f) %s \n", dCurPosX, dCurPosY,
unicode.GetStringUtf8().c_str() );
}
i get Unhandled exception and Access violation, becouse pszData - wrong
pointer.
can you help me? how i can correctly extract text from pdf with podofo?
i attache my dll and pdf. thank you.
