[jira] Commented: (PDFBOX-586) Text Extraction on Android

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

    [ https://issues.apache.org/jira/browse/PDFBOX-586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12874066#action_12874066 ] 

Bernard commented on PDFBOX-586:
--------------------------------

OK.

Once it works, I send you the sources with comment on all my changes.  But I'm only concerned on text extraction.  Rendering PDF would be nice, but is too much work.

In Android (and other custom Java env. ?)  AWT is really limited....

> 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....
