Andreas Lehmkühler commented on PDFBOX-586:
-------------------------------------------
It seems that this discussion leads to some sort of modularization of pdfbox.
Probably we should think about different modules like:
- core (as main module)
- textextraction
- rendering
- search
- examples
- ...
@Bernard
I'm using PDFBox in an other project and I've also minimized the dependencies
by deleting uneeded code. As a good start you should
- delete org.apache.pdfbox.examples.*
- delete all classes used for testing
- delete org.apache.pdfbox.ant.* (no more runtime dependency on ant)
if you don't need lucene integration:
- delete org.apache.pdfbox.searchengine.* (no more runtime dependency on lucene)
I've also removed the dependecy on the encryption jars, but I can't remember
what classes exactly have to be modified. All I know is, that it wasn't that
hard.
If you don't need rendering:
- delete org.apache.pdfbox.util.operator.pagedrawer.*
- remove all classes from org.apache.pdfbox.util.operator.* which aren't needed
for textextraction (see PDFTextStripper.properties)
- delete org.apache.pdfbox.pdfviewer.* (because of the missing class PageDrawer
you have to remove convertToIamge and print from PDPage)
- remove org.apache.pdfbox.PDFDebugger
- remove org.apache.pdfbox.PDFReader
- remove org.apache.pdfbox.PDFToImage
- ....
If you removed all of that, it should be easier to move on and to identify more
classes which aren't used anymore after deleting all the stuff above.
> Text Extraction on Android

> Key: PDFBOX-586
> URL: https://issues.apache.org/jira/browse/PDFBOX-586
> Project: PDFBox
> Issue Type: Improvement
> Components: Text extraction
> Affects Versions: 1.1.0
> Environment: Windows XP + Eclipse + PDFBox sources
> Reporter: Bernard
> Attachments: ASEB-Camping_Car_ou_Bateau.pdf, Eval.pdf, internals.pdf,

> 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....
