["Jukka Zitting (JIRA)" <ji...@apache.org>]

Jukka Zitting updated PDFBOX-586:
---------------------------------

       Summary: Text Extraction on Android  (was: Text Extraction Regression ?)
    Issue Type: Improvement  (was: Bug)

Sounds like the problem is caused by the changes you're making to the source code, so I updated this issue from being a regression bug to an improvement request to make PDFBox work better in the Android environment.

Can you please attach a patch of the changes you've made? We may want to incorporate some of the changes in PDFBox to make it easier to use with Android.

> 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....
