> Rendering pages from [^issuedFilePDF.pdf] (e.g. first page) results in
> missing shading pattern behind the line numbers.
> Expected: [^screen-capture-issuedFilePDF-page1-acrobatreader.png]
> Actual: [^issuedFilePDF.pdf-page1.png]
> Code:
> {code:java}
> byte[] fileBytes = Files.readAllBytes(Paths.get(pdfPath));
> DataInputStream data = new DataInputStream(new
> ByteArrayInputStream(fileBytes));
> try (PDDocument pdfboxDocument = PDDocument.load(data)) {
> PDFRenderer renderer = new PDFRenderer(pdfboxDocument);
> renderer.setImageDownscalingOptimizationThreshold(0.2f);
> BufferedImage bim = renderer.renderImageWithDPI(pageIndex, 72,
> ImageType.RGB);
> File outputFile = new File(pngPath);
> ImageIO.write(bim, "png", outputFile);
> }
> {code}
> Is this incorrect pdfbox usage, or is this a pdfbox issue?
