pdf

问题 I was able to create a PDF with PDFBox (version 1.8.9) and then convert it to a PostScript file with the following code: DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PRINTABLE; StreamPrintServiceFactory[] factories = StreamPrintServiceFactory.lookupStreamPrintServiceFactories(flavor, DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType()); if (factories.length == 0) { throw new PrinterException("No PostScript factories available"); } PDDocument document = pdfGenerator.getDocument(); // Attributes

问题 R creates a session-specific temp directory in a subdirectory of TMPDIR using mkdtemp(), and removes that directory tree when R exits. This directory is used by default when calling tempfile(), and when calling pdf(). I have found that for some very long-running (e.g. 2 day) Rscript jobs, the session-specific temp directory appears to be gone. I get a "No such file or directory" error produced by plot.new(), or similar error writing to a path created with tempfile(). I've used the same code

问题 I try to sign a pdf file using my smartcard (USB token) but encounter "Document has been altered or corrupted since it was signed" error when I open the signed pdf file in Adobe. The error is not so descriptive and I'm not sure where to look at because the code seems good to me but apparently it's not.. The code that I use is: var signer = smartCardManager.getSigner("myTokenPassword"); var toBeSignedHash = GetHashOfPdf(File.ReadAllBytes(@"xxx\pdf.pdf"), cert.asX509Certificate2().RawData, "dsa

问题 I want to Export HTML to PDF using jQuery that is working fine but only for when HTML will finish in single page PDF. But I'm facing difficultly export html to PDF when there is lots of data in html and PDF pages may be more than one. My code: $("body").on("click", "#downloadPDF", function () { html2canvas($('#downloadPDFData')[0], { onrendered: function (canvas) { var data = canvas.toDataURL(); var docDefinition = { content: [{ image: data, width: 500 }] }; pdfMake.createPdf(docDefinition)

问题 I am working on a personal project where I want to have a functionality where I can pick up a pdf file from the file system and read the content of it by ANYHOW. I tried every possible library out there but nothing works and most of them no support any more whatsoever. I am testing on ios by the way. an example of my standpoint would be like: <View style={styles.buttonPdfContainer}> <Image style={styles.pdfIcon} source={require('../resources/pdf.png')}/> <TouchableOpacity onPress={() => { //

问题 I made handwritten slides using an iPad app, and found out that the line was too thin to be projected on a big screen in a room. Unfortunately that app doesn't have the ability to change the stroke widths afterwards... (geez.) But I have the exported PDF file. As a programmer I should be able to solve my problem programmatically, by changing the width of all lines on a PDF by, say, a factor of two. So, my question is what would be the easiest way to achieve my objective. Is there a Perl

问题 SwiftUI, macOS: I'm trying to get a menu item to open "default PDF viewer of your choice", with a specific bundled PDF. Here's what I have thus far: import SwiftUI import WebKit import PDFKit func Guide1(_ sender: Any) { if let pdfURL = Bundle.main.url(forResource: "Guide1", withExtension: "pdf"){ if NSWorkspace.shared.open(pdfURL) { } } } func Guide2(_sender: Any) { if let pdfURL = Bundle.main.url(forResource: "Guide2", withExtension: "pdf"){ if NSWorkspace.shared.open(pdfURL) { } } } Now,

问题 I would like the HTML from a Google Apps Script form, to get two different styles, one for the body of the email and another for the PDF file. Current code: function doGet(request) { return HtmlService.createTemplateFromFile('index') .evaluate();//not all caps but it has to match the name of the file and it doesn't - Change to PAGE } function include(filename) { return HtmlService.createHtmlOutputFromFile(filename) .getContent(); } /****** SHEET ****/ function userClicked(userInfo){ var url =
