(I'm sorry that I couldn't do anything for a few days)

Pdfbox can't extract the diagonal texts. I had a test today, too.

 

1. The content of my pdf file is like this:

Unable to render embedded object:

 

2. My test program is as follow..

  PDDocument doc = null;
   
   try {

    doc = PDDocument.load(file);

    PDFTextStripper parser = new PDFTextStripper();

    String text = parser.getText(doc);

    System.out.println(text);

  } finally {

    if (doc != null)

      doc.close();

  }

 

3. The results are as follow..

PDFTextStripper extracts only texts rotated 90, 180, 270 degrees.

PDFStreamEngine.showGlyph(...) is same.

 

(The attached pdf file was created from MS Powerpoint)

> The PDFBox (StreamEngine) extracts only texts that are rotated by 0, 90, 180 
> or -90 degrees.
> For example, it can't extract texts rotated by 45 or 60 degrees.
