Has anyone used a service that offers an API to render PDFs? Would you recommend it? PDFcrowd renders superb pdfs, and I'd love to integrate it to my codeigniter project.
Any advice? If somebody has done this, would you mind sharing some helpful hints/code?
Perhaps not what you were looking for, but PrinceXML is an application which you can embed in a web-server as a service. It has very good CSS & HTML support and a great layout engine.
It can be used as a command-line app, in Java, PHP, ASP, etc.
Suggest to look at http://www.web2pdfconvert.com/pdf-api.aspx Online Web to PDF API, fast and produce excellent PDF.
I found TCPDF easy to install and use - it also comes with a lot of neat extra's, such as QR code generation.
