How to extract fonts from PDDocument in PDFBox 2.0.2

问题

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

How to extract font styles of text contents using pdfbox?

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

Thanks

Do this:

PDDocument doc = PDDocument.load("C:/mydoc3.pdf");
for (int i = 0; i < doc.getNumberOfPages(); ++i)
{
    PDPage page = doc.getPage(i);
    PDResources res = page.getResources();
    for (COSName fontName : res.getFontNames())
    {
        PDFont font = res.getFont(fontName);
        // do stuff with the font
    }
}

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

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