wkhtmltopdf

问题 I'm looking to start with an initial PDF file, one that has graphics and text, and then take some html code which has dynamic values for some user input, generate that as a PDF, hopefully either using the initial PDF as a background, OR somehow running a PHP script afterwards to "merge" both PDF where one acts as a background to another. I have some code that renders an HTML formatted PDF: (using DOMPDF) $initialpdf = file_get_contents('file_html.html'); $initialpdf = str_replace(array( '

In HTML format the report is displayed fine. I did some research and found that downgrading the wkhtmltox to version 0.21.1 would solve this problem.

问题 I'm trying to print pages, using wkhtmltopdf, that are protected by auth filter in Laravel. I'm using the standard session cookie -- in config/session.php: 'driver' => 'cookie', 'cookie' => 'laravel_session', But passing the session cookie does nothing, i.e: $ wkhtmltopdf --cookie laravel_session [cookie value] http://myurl.com/protected test1.pdf just prints the login page. Anyone know if there is some special stuff that needs to be done when passing auth cookies to laravel, or what else i

问题 I'm using CFPDF to merge multiple PDFs together. The PDFs were created using wkhtmltopdf 0.12.1. In most cases the code works fine, but 2 of my documents error whenever merged together. My online searches came up empty and I'm really at a loss.

问题 I'm wondering how i can go about reducing the font size on the generated table of contents. I've read and reread their documentation here: https://wkhtmltopdf.org/usage/wkhtmltopdf.txt The bit i'm confused on is: The generated XML document can be viewed by dumping it to a file using the --dump-outline switch. For example: wkhtmltopdf --dump-outline toc.xml http://qt-project.org/doc/qt-4.8/qstring.html qstring.pdf I'm having difficulty understanding how to translate to my own project, and what
