Extensions / Scripts for pyFPDF (fpdf2)

This repository contains some of the original FPDF PHP Scripts that were ported to Python to be used in conjunction with fpdf2 (as well as some new scripts).

My main goal was on translating the scripts 1:1 without a focus on "pythonic elegance" or optimizations.

Some of the functions demonstrated in these scripts have already found their way into fpdf2. Whenever possible, you should use the alternatives implemented in fpdf2. On the other hand, some functions in the scripts may work (slightly) different and add value to your projects or adress edge cases.

It is possible that the scripts do not work correctly with newer versions of fpdf2 or Python! Please check the "Tested with" info for each script.

Alpha / Transparency for pyFPDF (fpdf2)

This script adds transparency support to pyFPDF. You can set the alpha channel from 0 (fully transparent) to 1 (fully opaque). It applies to all elements (text, drawings, images).

Tested with fpdf2 2.4.5, Pillow 8.3.1, Python 3.8.10

Visibility feature

This script allows to restrict the rendering of some elements to screen or printout. This can be useful, for instance, to put a background image or color that will show on screen but won't print.

Note: this feature is not supported by all PDF viewers.

Some Test on Ubuntu 20.04:

• Chromium 94.0.4606.81 (Works as intended)
• Google Chrome 94.0.4606.81 (Works as intended)
• Evince 3.36.10 (Does not display content marked for screen display, but displays content marked for printing)
• Okular 21.08.2 (Same result as for Evince)
• Firefox 93.0 (Ignores restrictions and displays all content)

Script was tested with fpdf2 2.4.5, Pillow 8.3.1, Python 3.8.10
