How To Install potrace on CentOS 8
Introduction
In this tutorial we learn how to install potrace on CentOS 8.
What is potrace
Potrace is a utility for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP format), and the default output is an encapsulated PostScript file (EPS). A typical use is to create EPS files from scanned data, such as company or university logos, handwritten notes, etc. The resulting image is not “jaggy” like a bitmap, but smooth. It can then be rendered at any resolution. Potrace can currently produce the following output formats PDF, SVG (scalable vector graphics), Xfig, Gimppath, and PGM (for easy antialiasing). Additional backends might be added in the future. Mkbitmap is a program distributed with Potrace which can be used to pre-process the input for better tracing behavior on greyscale and color images. potrace 1.15 3.el8 x86_64 122 k potrace-1.15-3.el8.src.rpm appstream Transform bitmaps into vector graphics http GPLv2+ Potrace is a utility for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image.

Install potrace on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
