Tagged Content, Tagged annotations, Tagged Form Fields passed in the Accessibility check for the document I am trying to fill using itext. I am getting this error when i am trying to fill the document from java code using itext library.

问题 I've looked around quite a bit but I can't seem to find any examples of the use of these 2 libraries together. My project currently uses react-pdf to generate pdf reports but I need to add chartjs charts to some of the new files we'll be generating. I would prefer not to have to use two different pdf libraries and have to re-code parts of the application to match 2 standards. If there is a different library that can get the job done I would be open to suggestions. The page I am trying to

问题 I want to embed an mp4 video (with H.264 codec) into a pdf with Latex, using the media9 package. There are no error messages during compilation. Before activating the video in the pdf, there is a still image (as intended), but after activation, there is just a black window, without the video being played properly. A minimal example to illustrate is given below. It is a shortened version of an Overleaf template for embedding mp4 files into pdf documents with Latex. I have attached the still

问题 I want to display a local PDF file through a new view when I tap a button. I tried doing that using a UIViewRepresentable WebView but it's not working (I have worked with WebView only through NavigationList). I leave my code, but feel free to suggest better option if the WebView is not the most optimal. ButtonView import SwiftUI struct ResumeView: View { let sfSymbol: String let text: String let fileUrl = Bundle.main.path(forResource: "Resume", ofType: "pdf") var body: some View {

问题 In web app I'm using the JSPDF Autotable to build a PDF. The problem is that the data will be dynamic (I'm going to use AngularJS 1.x) and so the rows can have differents height. In some cases, Autotable breaks the last row of the page, continuing to the next one. How can I prevent this behavior, and set up Autotable to take the last row (which default would break) and bring it to the next page? This is my code: https://jsfiddle.net/9vgxvfkh/1/ I guess I have to change some settings in the

问题 I'm trying to send an email with a PDF attachment using the phpmailer class. I used this code: Within mailTo function: $mail->AddAttachment($pdffile); where $pdffile = $_SERVER['DOCUMENT_ROOT'] . "/facturen/test.pdf" Sending the mail results in an email without attachment but with: --b1_3768f40f33d9a5dec555d03a15af14f9 Content-Type: text/html; charset = "iso-8859-1" Content-Transfer-Encoding: 8bit at the top of my email and on the bottom of my email: --b1_3768f40f33d9a5dec555d03a15af14f9

问题 I'm trying to get pdf.js to work in IE. I've copied the code almost exactly from the "Hello World using base64 encoded PDF" example on the pdf.js site at https://mozilla.github.io/pdf.js/examples/. The PDF is upside down and mirrored. I've looked around and a common cause of this is re-using the canvas for multiple renders, but I'm not doing that I'm just rendering once, so I really have no idea. At the top of my html document i have: $html .= '<canvas width="600px" height="2000px" id="the
