> Hello,
> I am working with pdfbox to transform input pdf files to images, which are later fed to an OCR library. It works perfectly in most of the cases but I stumbled upon this particular case in which all text disappeared from the rendered image.
> My source code for the method which converts the pdf into images:
>
> {code:java}
> public List<BufferedImage> splitPdf(File pdfFile) throws IOException {
> List<BufferedImage> result = new ArrayList<>();
> PDDocument document = PDDocument.load(pdfFile);
> PDFRenderer pdfRenderer = new PDFRenderer(document);
> for (int pageIndex = 0; pageIndex < document.getNumberOfPages(); pageIndex++) {
> result.add(pdfRenderer.renderImage(pageIndex));
> debugPageImageInfo(result.get(result.size() - 1));
> }
> document.close();
> return result;
> }
> {code}
>
> I attached to this issue the pdf file for which I identified the problem and the resulting images.
>
> I hope this is helpful for anyone else encountering the same problem!
