pdfChip in a Nutshell
This short chapter will get you up to speed with what pdfChip is and it will introduce the other chapters so that you can decide whether you want to read this introduction from cover to cover or jump to specific chapters instead.
What is it?
But pdfChip also understands extensions to the HTML and CSS languages which allow it to support features that regular HTML and CSS would not have an answer for; this includes support for pagination, extended color spaces, metadata and much more.
The output of pdfChip is a high-quality PDF document. The high-quality aspect means that:
- the PDF code is highly efficient, so that documents with many thousands of pages can be generated that are still very compact. The conversion engine is optimised so that it doesn't generate unnecessary content and includes elements which are used multiple times only once in the PDF document.
- the PDF can be generated in such a way that it is immediately usable for publishing, print production, archival and other professional uses. The ISO PDF/X and PDF/A standards are supported, custom metadata can be included, colors can be specified correctly for a wide range of applications etc…
A Command-Line Application
pdfChip does not come with a user-interface. Instead it has to be controlled through its command-line interface (or CLI), either by using it in a terminal or command-prompt window, or by integrating it through scripting or a high-level programming language. With its lack of external dependencies, small footprint and fast operation, this makes pdfChip especially suited for integration in web-based or cloud-based applications where it can be used to turn any information into high-quality PDF for further processing.
How does it work?
pdfChip <Path to HTML file> <Path to PDF file>
Assuming in a terminal window you are in the folder where the pdfChip application is installed and in that folder there is also a file called 'index.html', you could convert this HTML file into a PDF by issuing the command:
./pdfChip index.html result.pdf
The tutorial (introduced in the chapter "Learning pdfChip - the Tutorial") contains much more elaborate examples, but the command-line will always remain relatively simple. Of course the real power (and complexity) lies within the HTML file that is converted.
Built on WebKit
Because pdfChip converts HTML into equivalent PDF documents, it is built on top of the WebKit rendering engine. WebKit is the name of the open source web browser engine, used for example by Mac OS X and Safari. Because pdfChip is built using the cross-platform QT framework, it uses the QT WebKit variant to do its work.
Because the HTML object model is rather limited when seen in the context of professional publishing workflows, print production workflows, or archival workflows, the WebKit implementation in pdfChip has been extended. A variety of additional HTML elements and CSS attributes have been introduced to allow generating PDF objects that cannot be described correctly with standard HTML and CSS. The chapter on “Main Features” describes many of these extensions in principal; the pdfChip Reference Manual details them.
