libvips VS Jansson

After some research, I found libvips, a demand-driven, horizontally threaded image processing library. It is designed to run quickly while using as little as memory as possible.

Sharp is a fast and efficient image optimization Node.js module that makes use of the native libvips library.

h2non/bimg can handle both if the underlying libvips is compiled with support for both formats.

if you're using linux (which it doesn't seem so) there's also vispdisp https://github.com/jcupitt/vipsdisp which is based on https://github.com/libvips/libvips which will likely take over how images are decoded in the future for everything, at least methodology wise.

The magic happens by way of a library called Libvips, which contains an ultra-high-speed low-memory image resizer.

imagor uses one of the most efficient image processing library libvips. It is typically 4-8x faster than using the quickest ImageMagick and GraphicsMagick settings.

Try the solutions here: https://github.com/libvips/libvips/issues/2479

in that case maybe take a look at https://github.com/libvips/libvips

libvips v8.6+ or ImageMagick for image analysis and transformations

I'm a fan of jansson easy to use and great documentation

Context: I needed to emit rather complex compound JSON data for a C-based project I'm working on. I could do it all with sprintf(), but it got messy quickly. I looked at available libraries such as jansson and CCAN's json, but they both used malloc(), which isn't an option in my case.

I find jansson quite usable and minimal: https://github.com/akheron/jansson

JanSON has been really good for my uses. Simple, intuitive, fast.

I don't see why something like Jansson wouldn't.
