pdfkit

问题 I´m working on an app with Apple's PDFKit and have managed to put some Annotation-Buttons with a working PDFActionURL , which open the iOS standard browser after tapping on them. Unfortunately, I did not find a working solution, how to open the associated links in an In-App-Browser or to load it in a webview. After tapping the AnnotationButton PDFKit automatically opens Safari and I haven´t found a property or another way concerning iOS to influence this behavior by manipulating f.e. the

问题 I have a PDFView that's set to use a pageViewController: let pdfView = PDFView() let pdfDoc = PDFDocument(url: Bundle.main.url(forResource: "test", withExtension: "pdf")!) pdfView.document = pdfDoc pdfView.autoScales = true pdfView.displayDirection = .horizontal pdfView.usePageViewController(true, withViewOptions: [:]) Whenever I swipe to get to the next page, said next page is blurry for half a second before it's rendered sharply. That is quite annoying. Can I somehow preload the pages? I

问题 My wkhtmltopdf PDF output of a page with several Highcharts charts on it is missing some elements of the charts, primarily all of the simple straight lines, including tick marks, grid lines, column borders, legend borders and the lines in my line/spline charts (data points display).

问题 I'm having trouble generating a PDF out of a html page. I'm using PDFkit. In the process of installing it, I noticed I needed wkhtmltopdf. So I installed it too. I did everything PDFkit's documentation said to do.. and now I'm getting this error when I try to load the PDF. Here is the error: command failed: "/usr/local/bin/wkhtmltopdf" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-"

问题 I'm building an app to edit PDFs on iPad. I'm trying to implement the dragging of the annotations with a panGesture recognizer that I added to the superview of the PDFView. The problem is that the new rect bounds of the annotation gets assigned but the changes doesn't reflect on screen. Here is my code: @objc func handlePanGesture(panGesture: UIPanGestureRecognizer) { let touchLocation = panGesture.location(in: pdfView) guard let page = pdfView.page(for: touchLocation, nearest: true) else {

问题 I'm trying to write metadata to a pdf file using the following python code: from Foundation import * from Quartz import * url = NSURL.fileURLWithPath_("test.pdf") pdfdoc = PDFDocument.alloc().initWithURL_(url) assert pdfdoc, "failed to create document" print "reading pdf file" attrs = {} attrs[PDFDocumentTitleAttribute] = "THIS IS THE TITLE" attrs[PDFDocumentAuthorAttribute] = "A. Author and B. Author" PDFDocumentTitleAttribute = "test" pdfdoc.setDocumentAttributes_(attrs) pdfdoc.writeToFile_

问题 After adding annotation to PDFPage (and rendering it on a screen), there is no way to update its appearance on PDFPage / PDFView . To reproduce the problem: Create PDFAnnotation and add it to the PDFPage : let bounds = CGRect(x: 20.0, y: 20.0, width: 200.0, height: 200.0) let annotation = PDFAnnotation(bounds: b, forType: .widget, withProperties: nil) annotation.widgetFieldType = .text annotation.backgroundColor = .gray annotation.font = .systemFont(ofSize: 18) annotation.widgetStringValue =
