How to render HTML and graphics on top of existing PDF using wkhtmltopdf

Question

I have these inputs:

• an HTML page
• an Existing PDF, and some more HTML/stuff I want to draw on top of that PDF (text, html, circles)
• an HTML Page

I want to render a 3-page PDF, and have them all be displayed on in a single PDF.

In other words, my question is How do I use an existing PDF as a template for more input

Can this be done from PHP and how?

Answer 1

不幸的是，使用wkhtmltopdf，您无法修改/编辑现有的PDF。

With a custom XSL using this code, you could easily do it.

The backend rendering engine is XSL FO based which supports injecting a PDF as a background image.

So easy, I did you a sample. Go to this page:

Click the Open-> PDF button. The "Top Secret" PDF is injected as a background, the HTML overlayed on top. You can use this solution to combine your HTML, PDF and HTML+PDF in any way you wish.

In fact, with HTML, this Javascript and a little customization you could have a document that was:

start document

format HTML div
format HTML div with this PDF background
format another HTML div
inject this entire PDF
format another HTML div with a different PDF background
inject a different entire PDF
...

end document
