Aspose.Pdf is a .NET PDF component to write PDF documents without using Adobe Acrobat. It supports form field creation, document, text and page properties, color space, text, heading, and attachment settings. It lets you create PDF documents by using its API with XML templates and XSL-FO files. It also converts HTML, XSL-FO, and MS Word to PDF. Other features include image formats and security features, hyperlinks, the ability to add footnotes, automatic fitting to content in a table, decimal Tab stops, HTML tags, and keeping paragraphs together when breaking pages.
PDF Automation Server (PAS) can receive PDF documents from multiple sources concurrently, including email, FTP servers, and local or network folders. Processes can then be defined independently for each document source to perform a number of different functions on the documents. Finally, PAS can route the original or modified document to multiple destinations, including folders, printers, email, and FTP servers. PAS supports the following PDF processing functions: printing, setting security, conversion to images, merging, flattening, and extraction of form field data, importing, exporting, and flattening of annotations, text extraction, assembling, splitting, merging, digital signatures, and stamping.
PDFXMLRPC enables client-server PDF creation from text over the Internet or an intranet, running over XML-RPC and HTTP. It consists of a library that you can use to create an XML-RPC PDF server, a library that you can use to create an XML-RPC PDF client, and clients created using these libraries. The client can send text to the server repeatedly, using XML-RPC method calls. The server converts that text to PDF content, and in response to a different method call from the client, sends that PDF content back to the client. The client then saves that PDF content to a local PDF file.
CPDFTK is a commercial, supported implementation of pdftk. It is a set of command line tools for manipulating PDF files with the same interface as the popular open source pdftk tools. It can split, merge, linearize, scale, rotate, crop, encrypt, decrypt, watermark, bookmark, annotate, attach, and impose files.
Aspose.Words for SharePoint allows you to convert documents within the Microsoft SharePoint applications. It supports multiple document formats like PDF, DOCX, DOC, RTF, MHT, TXT, XML, ODT, EPUB, and XPS. It is designed to be used with Windows SharePoint Services and Microsoft Office SharePoint Server 2007 (standard and enterprise). You can also use different valuable options during conversion setup like converting files in subfolders or saving destination folder options.
The Hummus PDF Writer library allows you to generate PDF files. It was developed with a principal “one-off” method of generating PDF files. Adhering to this idea, it is both fast and retains a low memory signature regardless of how large the file grows. The library has a set of high level features for adding content to a PDF, including creation of pages; drawing primitives and any of the simple PDF operators for drawing content; embedding of PDF, JPEG, and TIFF images; Unicode text support with Type1, TrueType, and OpenType fonts; and defining reusable objects using XObject Forms. You can also use the library as a PDF parser. The library is very extensible. It is easy to implement more PDF features by using the lower level set of methods, which provide access to the PDF building blocks themselves. Adding a feature requires you to be familiar with the PDF formatting of that feature, but will not require you to write the basic PDF building blocks, as the library handles this.
jPDFFields is a Java library for working with interactive PDF forms in both AcroForm and XFA formats. It allows your application to get and set field values, and can import and export to the FDF, XFDF, and XDP formats. It can also "flatten" fields in a document. (Flattening is the process of merging the fields into the PDF content layer so the information is retained, but as static PDF content.) jPDFFields is built on top of Qoppa's proprietary PDF technology, so it is 100% Java and does not require any third party software or drivers.
