How can I create images from pixels definitions ingame ? (rgba)

[Tchernobill]

I have an algorithm that extracts data from the game engine and I wanna synthetise it as an image storing data in RGB and Alpha.

I could also store it as text and use an external tool to do the text to image conversion, but this would remove some options.

 

1/ Snippet

From internet I found https://github.com/wyozi/lua-pngencoder that seems to do the job but requires "bit" base library that seems not accessible to my mod.

Anyone has any idea how to use "bit" in a pz mod ?

Also I intend to produce BIG images and I'm not sure it will do the trick. If it does I am afraid of lua performances.

 

2/ Ingame tools

2a/ ImageUtils.saveImage

This function is based on an ingame Texture type.

It only seems to work for creating "png" but I am totally ok with that.

One Texture constructor seems promising for use from lua:

public Texture(String var1, int[] var2);

How can I fill var2 with my RGBA values ?

 

3/ Any other idea on how to create images ingame is welcome.
