For PDFBox 2.x the revised code for the answer you are linking to is

<pre><code>PDDocument doc = PDDocument.load("C:/mydoc3.pdf");
for(PDPage page : doc.getPages()){
 // get the names of the fonts in the resources dictionary
 Iterable&lt;COSName&gt; iterable = page.getResources().getFontNames();
 // to get the font for each item call
 // page.getResources().getFont(COSName name);
}

This one is to Extract font of the Pdf file using pdfbox 2.0.6.

 for (int i = 0; i &lt; pddDocument.getNumberOfPages(); ++i)
 {
 PDPage page = pddDocument.getPage(i);
 PDResources res = page.getResources();
 for (COSName fontName : res.getFontNames())
 {
 PDFont font = res.getFont(fontName);
 System.out.println("FONT :: "+ font);
 }
 }

 pdfMeta.setFontName(font); 
}
</code></pre>

I have seen how to do this in previous versions like below:

<a href="https://stackoverflow.com/questions/6939583/how-to-extract-font-styles-of-text-contents-using-pdfbox">How to extract font styles of text contents using pdfbox?</a>

But I think the getFonts() method has been removed now. I want to retrieve a map of texts to fonts (<code>Map&lt;String, PDFont&gt;</code>) in the new version of PDFBox but I have no idea how.

Thanks
