pdf.js

问题 My problem may seem a bit vague (it is to me too), but here is my attempted explanation of it. A few months ago, I implemented PDF.js in my web application. It was really useful, and I am using it for interactions with my clients. Suddenly, last week, my clients reported to me "Aw, Snap" messages in Google Chrome on their PCs when they try to launch PDF.js. I have an iMac and two PCs at home, so I decided to test this out. When I used Google Chrome on my iMac to launch PDF.js, I found it

问题 I know of a similar question to this one: Pdf.js: rendering a pdf file using a base64 file source instead of url. That question was awesomely answered by Codetoffel but my question is different in that my PDF is retrieved via a RESTful call to my Web API implementation. Let me explain... First, here's a basic way to use PDF.JS to open a PDF via a URL: PDFJS.getDocument("/api/path/to/my.pdf").then(function (pdf) { pdf.getPage(1).then(function (page) { var scale = 1; var viewport = page

问题 PDF.js is the latest library from Mozilla, and is a standards-based PDF renderer that is written entirely in Javascript. Currently you cannot access the generated HTML, and the library can only be used as a viewer. Is it possible to use PDF.js to statically convert a PDF to its HTML equivalent? Considering it renders in a browser, it must be HTML+CSS, and the JS would be used only for navigation. After converting it to HTML I plan to use our existing HTML workflow to import/index/consume the

问题 In the given code only else condition is running every time. I have used pdf.js library and trying to break the pdf in chunks. I user this code on server side but it seems like only else condition is running and perhaps isset($_SERVER['HTTP_RANGE'] returns null . So the pdf gets loaded in the first go itself . if(isset($_SERVER['HTTP_RANGE'])) { $fp = @fopen($filepath, 'rb'); $size = filesize($filepath); // File size $length = $size; // Content length $start = 0; // Start byte $end = $size -

问题 I'm using mozilla/pdf.js to display a pdf in a webview in my Android application. The framework doesn't need any internet connection to render the pdf. If downloaded the .js file and everything so it can use that. Still every time I want to open a new pdf Android opens the default browser with the wireless settings dialog. After closing the app and opening it again the PDF is rendered. My internet connection both wireless as data is disabled, so it doesn't need anything of internet, I'm sure

问题 I'm having a problem extracting text from a pdf using PDF.js. I'm using a PDF that was exported from Excel, and thus has multiple rows/columns. Here's the function I'm using to get the text: gettext: function(url, name){ var self = this; var data = url; console.log('attempting to get text'); return pdfjs.getDocument(data).then(function(pdf) { var pages = []; for (var i = 0; i <= 1; i++) { pages.push(i); } return Promise.all(pages.map(function(pageNumber) { return pdf.getPage(pageNumber + 1)

问题 I am using pdf.js. Fetching the Text I get blocks with font info Object { str: "blabla", dir: "ltr", width: 191.433141, height: 12.546, transform: Array[6], fontName: "g_d0_f2" } Is it possible to get somehow more information about g_d0_f2 . 回答1: Notice the PDF.js getTextContent will not and not suppose to match glyphs in PDFs. The PDF32000 specification has two different algorithms for text display and extraction. Even if you can lookup font data in the page.commonObjs, it might not be

问题 With pdf.js is there a way to programmatically change the current page of a PDF being viewed? For example, a call to change the current page to page 5. (I know that I can initially set the page by specifying the page number in the URL, but I want to change it programmatically after it has been opened.) 回答1: PDFViewerApplication.pdfViewer.currentPageNumber is a getter and setter. Examples: // Go to page 5 PDFViewerApplication.pdfViewer.currentPageNumber = 5; // Move two pages forward
