阅读更多关于 Generate PDF on the server from Google Maps API?

问题 We have a hosted web app that uses the Google Maps API for various types of geographical reports, using a combination of the javascript API for adding markers and shapes, plus KML overlays for other layers. There's some demand from customers for turning these into nice downloadable & printable PDF maps. I'm not sure where to begin with that.

Export HTML to PDF (C++, Windows)

阅读更多关于 Export HTML to PDF (C++, Windows)

问题 I am looking for a redistributable component to convert HTML to PDF. I would - at the moment - like to avoid using a "PDF printer", as this requires a printer installation and some user "playing around" in the printers panel might break that feature. The HTML is available in a Browser control or as external file. The HTML is normally fairly simple, but customers can create their own templates, so a "good range" of HTML should be supported. Should be accessible for an automated process from C+

阅读更多关于 itext xmlworker with javafx htmleditor

I created a simple JavaFX (2.2) FXML project. I am trying to convert a html string to different Elements and add them to a Paragraph in my PDF document generated by iText. As HTMLWorker is deprecated, I use XMLWorker. It does seem to work with a own written simple html string, e.g.: StringReader in = new StringReader("<html><body><p>test</p></body></html>"); However, when I try to use the html string generated by the JavaFX HTMLEditor control, I receive following message: Caused by: java.lang.NoSuchMethodError: com.itextpdf.tool.xml.html.pdfelement.NoNewLineParagraph.setMultipliedLeading(F)V

问题 I'm creating generator of pdf documents in Ruby on Rails with Prawn gem and I came up with issue that when I have Chinese, Japanese and Cyrillic chars they are displayed incorrectly.

Now this isn't the issue, but the fact that my documents will include all different possible chars that gTLD supports. Question 1: Do you know any font for generating pdf documents that will

阅读更多关于 Disallow editing but allow page extraction in Java iText / PDF

问题 I'm using iText to generate PDF files. I want to disallow editing of the PDF, but allow the reader to extract pages. Here's my code to set encryption: writer.setEncryption(null, null, 0xffffffff, PdfWriter.STANDARD_ENCRYPTION_128); The third parameter specifies permissions. I'm using 0xffffffff instead of the individual iText flags ALLOW_PRINTING etc. This will ask iText to enable everything. But this is what I get in the PDF file: I should think I should be allowed to enable extraction but
