Understanding PDF Format

We have been working with PDF files since 1999 and developed complex software to display PDF files. We have learnt a lot about the PDF file format in that time and share our knowledge in the articles below.

There are also a large number of technical terms used with PDF so we have created a Glossary of Terms with all the keywords.

If you are interested in using our software to display your PDF documents (we can rasterize them, convert them to HTML5 or SVG, or provide a complete Java PDF Viewer) pdf why not setup a call with us and see if we can help?

Here is an overview of the topics covered in this article:

Install cloudflared
Create /etc/systemd.system/cloudflared-proxy-dns.service with contents:

[Unit]
Description=DNS over HTTPS (DoH) proxy client
Wants=network-online.target nss-lookup.target
Before=nss-lookup.target

[Service]
AmbientCapabilities=CAP_NET_BIND_SERVICE

if i have a distribution of numbers from 0 to 800, some less than 1, what is the best way to put them on a scale from 0 to 1

To normalize a distribution of numbers from 0 to 800 to a scale from 0 to 1, you can use the min-max normalization technique. This method scales the data based on the minimum and maximum values in the dataset. Here's the formula for min-max normalization:

normalized_value = (value - min) / (max - min)

In your case, the minimum value (min) is 0, and the maximum value (max) is 800. So the formula simplifies to:

normalized_value = value / 800
