10 Best Open Source Image Processing Libraries in 2022

In Linux, there are so many codecs, extensions, and libraries for processing images, audio files, and video files. Earlier, we have seen how to play videos smoothly on Linux with all media player codecs. When it comes to talking about the graphics and image section on Linux, you need to find out the suitable extensions or library tools for better performance. Suppose you’re a media enthusiast or you work in a sector where you need to process images in various ways. In that case, you can’t rely upon just the default image process libraries on Linux. 

Best Image Processing Libraries


Most of the image processing libraries for Linux are unofficial and third-party. But, as these applications are mostly open-source, so you don’t need to worry about the integrity; if you’re a professional Linux user, you can verify the source codes.

The image processing libraries become functional with the core connection to the kernel. You can do image filtering, coloring, face detection, playing with the structure, and mathematical and numerical operations with the image processing tools and libraries. This post will see the best open source image processing libraries for Linux.

  • You can play with texts on the image

5. ImageMagick: Image Processing Libraries


ImageMagick

As the name says, ImageMagick, this one really is a magical tool for image processing. It can do both image processing and compressing. This is a tough combination of processing and compressing. It can handle more or less over 100 types of image formats like jpeg, png, webp, svg, etc. 

Besides the regular image process tasks, you can also do rotation, vertical image vector, image scaling, and many more. This library function is written in the C programming language, and it’s built under the GPL privacy license. 

Important Features

  • You can do format transforming from one format to another format
  • It allows the user to do image compressing and composing
  • You can draw your own shapes and 
  • Creators can do little animation and do doodling with this library 
  • You can render images after your editing 
  • You can use HDR mode for better image quality and accuracy

6. LibGD 


LibGD Image Processing Libraries

The LibGD is an open source image processing library tool for Linux and other systems. This tool is written in the C programming language, and it connects directly with the core kernel of Linux. It supports both jpeg, png, Gifs, and other formats. 

Image resizing, composing, and color corrections are the primary jobs of this open source library. Image processing can be a great job when you need to do work forensic and investigating work.
