jsPDF can't get any styling to work

阅读更多关于 jsPDF can't get any styling to work

I'm new to using jsPDF but and for the life of me I can't get any css to apply to this thing! I've tried inline, internal, and external all to no avail! I read in another SO post that since it's technically printing stuff to a file I need a print style sheet, and that didn't work either. I have a very basic page that I'm just trying to get any CSS to work with: JS: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> <script type="text/javascript" src="jspdf.js"></script> <script type="text/javascript" src="./libs/FileSaver.js/FileSaver.js"></script> <script type

Convert canvas to PDF

Is it possible to directly convert canvas to pdf using JavaScript ( pdf.js or something like that)? Is there another possible way like canvas to img and then img to pdf? Can you give me an example? You can achieve this by utilizing the jsPDF library and the toDataURL function. I made a little demonstration: var canvas = document.getElementById('myCanvas'); var context = canvas.getContext('2d'); // draw a blue cloud context.beginPath(); context.moveTo(170, 80); context.bezierCurveTo(130, 100, 130, 150, 230, 150); context.bezierCurveTo(250, 180, 320, 180, 340, 150); context.bezierCurveTo(420,

问题 I have a couple of PDF template files with complex content and several blank regions/areas in them. I need to be able to write text in those blank regions and save the resulting PDFs in a folder. I googled for answers on this question quite intensively, but I didn't find definite answers. One of the better solutions is PDF::Toolkit, but it would require the purchase of Adobe Acrobat to add replaceable attributes to existing PDF documents. The PHP world is blessed with FPDI that can be used to

问题 I'm creating a PDF using Flying Saucer (which dumps out CSS/HTML to iText to a PDF) and I'm trying to use CSS3 to apply an image header and footer to each page.

Best C# API to create PDF [closed]

阅读更多关于 Best C# API to create PDF [closed]

Can you recomend any PDF API for C#. Free is the best, but i dont mind paying for it. Update: I'm not sure when or if the license changed for the iText# library , but it is licensed under AGPL which means it must be licensed if included with a closed-source product. The question does not (currently) require free or open-source libraries. One should always investigate the license type of any library used in a project. I have used iText# with success in .NET C# 3.5; it is a port of the open source Java library for PDF generation and it's free. There is a NuGet package available for iTextSharp
