The two libraries we'll be using here are While we could use reportlab to draw the entire PDF, it's easier to design a template using external tools and then simply overlay the dynamic content on this.

We can use pdfrw to read our template PDF and then extract a page, onto which we can then draw using reportlab.

That allows us to overlay custom information from our app directly onto an existing PDF template, which we save under a new name. The page contains a number of fields which are to be filled. In this tutorial, we'll write a PyQt form which a user can fill in and then write that data out onto the PDF at the correct place.

The template is in A4 format. Save it in the same folder as your script. If you have another template you'd prefer to use, feel free to use that. Just remember that you'll need to adjust the positions of the form fields when writing it.

Qt includes a QFormLayout layout which simplifies the process of generating simple form layouts. It works similarly to a grid, but you can add rows of elements together and strings are converted automatically to QLabel objects.

Our skeleton application, including the full layout matching the template form more or less is shown below. The above will give us the following layout in a window when run. You can already type things into the fields, but pressing the button won't do anything yet -- we haven't written the code to generate the PDF or hooked it up to the button. The process is as follows The code is shown below, this doesn't require Qt, you can save to a file and run as-is.

When run the resulting PDF will be saved as result.
