vips 8.7.4 Multithreaded image processing system with low memory needs
VIPS is a demand-driven, horizontally threaded image processing library. It's particularly good at processing large images, working with colour, scientific analysis, and general research & development.
Compared to most image processing libraries VIPS needs little RAM and runs quickly, especially on machines with more than one CPU core. This is primarily due to its architecture which automatically parallelises the image workflows.
