PDFBox Pdf to Image losing QR Code “ColorSpace Pattern doesn't provide a non-stroking color”

Similar to this SO PDFBox - PDF to Image losing barcode The PDF in question: https://drive.google.com/file/d/0B13zTPQR9uxscXRMWjhsZ0doa00/view?usp=sharing There is minimal text, and a medium sized QR Code. I have tried many different solutions to convert this PDF page to an image using PDFBox/ImageIO, but so far the QR Code is always missing from the result. When I use PDFBox's PDFImageWriter I get this log: ColorSpace Pattern doesn't provide a non-stroking color, using white instead! I'm thinking that pertains to the QR Code. Is this expected behavior? Can someone else confirm PDFBox cannot

烈酒焚心 提交于 2019-11-28 14:08:33
I need help with adding Cyrillic value to a field using the PDFBox API . Here is what I have so far: PDDocument document = PDDocument.load(file); PDDocumentCatalog dc = document.getDocumentCatalog(); PDAcroForm acroForm = dc.getAcroForm(); PDField naziv = acroForm.getField("naziv"); naziv.setValue("Наслов"); // this part right here naziv.setValue("Naslov"); // it works like this It works perfect when my input is in Latin Alphabet. But I need to handle Cyrillic inputs as well. How can I do it? p.s. this is the exception I get: Caused by: java.lang.IllegalArgumentException: U+043D ('afii10079')

Tagged PDF with PDFBox

眉间皱痕 提交于 2019-11-28 13:41:00
Is it possible to create tagged PDF(PDF/UA) with PDFBox? It looks like PDFBox has an API for that (package org.apache.pdfbox.pdmodel.documentinterchange.taggedpdf ), but I can't find any tutorials or code examples. Using the code below, I generated a PDF file containing an image, and the screen reader NVDA (in my case) recognizes it and reads '... graphic Alternate Description'. However, the accessibility checker PAC 2 shows an error: 'Image object not tagged'. PDDocument doc = new PDDocument(); PDPage page = new PDPage(); doc.addPage(page); PDDocumentCatalog documentCatalog = doc
