Description

Hi,

I have noticed that I can extract text some PDF files in PDFBox 0.7.4 but for the same file, the same page, PDFBox 1.1.0 doesn't retreive any text, or the extraction is worst.

Am I the only only one who think there is a regression in text extraction ?

My code is like this :

   PDDocument document = PDDocument.load("/sdcard/internals.pdf"); 
    int numberOfPages = document.getNumberOfPages();
    resources = this.getResources();
  
  android.util.Log.d(TEST_PDFBOX, "readerPDF() resources : "+resources);  // ANDROID code here to get file
   resourceGlyphList = R.raw.glyphlist;
   InputStream rawResource = resources.openRawResource(R.raw.pdftextstripper);   // PDFBOX property file
   android.util.Log.d(TEST_PDFBOX, "readerPDF() rawResource : "+rawResource);
   Properties properties = new Properties();
    properties.load(rawResource);
    		
   PDFTextStripper stripper = new PDFTextStripper(properties );
    		
  stripper.setStartPage(pageNumber );    //   1 or any other page
  stripper.setEndPage(pageNumber );   // same page as above

   String s = "Page : "+pageNumber+"<br><br>"+stripper.getText(document);
   android.util.Log.d(TEST_PDFBOX, "readerPDF()  stripper extract pages text : "+s);

Maybe I should use page.getContents().getStream() or stripper.getTextForRegion( "class1" ) or stripper.writeText(doc, outputStream)

I want the text as a String, not as a newly created file....
