New user with questions about programming with krita

[oscar_adalid]

Hello, it is possible to program brushes with scripts, as it happens in firealpaca?

1. Can someone provide me with a simple example that paints a round brush with the tablet?
   A simple example and how to program is appreciated.
2. Is there a function get_pixel and put_pixel?
   3.If so, I would like to implement them in krita. If it is very difficult, I don’t know how to program it here, I can show an example of them and someone expert in programming implements it, they should only pass my algorithm to krita.
   All the best.

No it’s not possible to script brushes and there’s no easy way to programmatically paint. That’s not what the scripting support is meant for in Krita.

There was a merge request for expanding the API to draw programtically. Although I don’t know if it had brush support

KRITA does not support doing this now. You can refer to this post:

[proof-of-concept] Scriptable Brush

[Lua Scripted Brush for Krita] Explanation This is a quick experiment that I did for fun. It demonstrates a way of making scripptable brushes via Lua. In the video I played with drawing speed and drawing angle. I’d really wanted to use pressure, but I don’t have my tablet with my dev environement I chose Lua because it’s simpler to embed in C/C++. I hacked the pixel engine by adding a new “dynamic sensor”, which exposes other sensor values and run a lua script to calcu…
