wkhtmltox wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely "headless" and do not require a display or display service. There is also a C library, if you're into that kind of thing. NOTE for SlackBuilds.org: This is a repackage of the official prebuilt binaries and provides the same commands as wkhtmltopdf at SlackBuilds.org (which builds from source). Only one of them should be installed. The official prebuilt binaries are made with a specially patched, statically linked Qt, so the provided utilities have extra functionality, such as better margin control and multiple file convertion. This is primarily needed for Publican to work correctly.
