intensifies VS piet

It looks like you already found a solution and imageproc is out of date, but I'll plug an open source solution I had which accepts an image upload and adds [x intensifies] and makes the image shake, just in case it's useful as reference. https://github.com/JosephCatrambone/intensifies Looks really closely related to what you wanted? Maybe?

You can even check https://github.com/linebender/piet and https://github.com/RazrFalcon/tiny-skia. They are pure rust libraries. Skia as a whole is a big binary to add.

First, at the deepest level, we are moving away from Piet, which is a cross-platform 2D graphics abstraction. Under the hood it uses whatever the standard OS API is. Instead we will be using Vello which we have been building as a research project for years already. It is starting to near its v0.1, which is very exciting. Fundamentally it is a novel GPU accelerated 2D rendering engine with a strong focus on performance. It is not ready for benchmarks yet, but we're confident it will deliver. If you're curious, you can check out the Vello roadmap for 2023.

you can use piet, although that is more of an abstraction over existing, platform-dependent libraries. So not really pure rust, but definitely cross-platform.

Piet is the backend for the Druid UI framework. It is indeed cross-platform. The SVG backend looks like it would work without an OS, but I'm not sure the value of a GUI toolkit without an OS anyway :)

Piet can render text. You can use Piet_common with the BitMapTarget to generate images Here is an example.

Piet (https://github.com/linebender/piet) should work.

So the 3 I'm looking at right now are 1. druid 1. piet 1. bevy

It relies on piet 2D graphic library; on Linux that means GTK/Cairo 2D primitives
