Overview

The package supports most notable file formats used in Arma 3. Reading is implemented for all supported formats, but writing is only available for some, where it makes sense.

ArmaIO does not come with in-depth authoring utilities. The data is read and presented in relatively thin wrapper structures, with minimal transformation of the data structures of the files themselves. As such, ArmaIO is most suited to be used as a middle layer to handle file IO in a more complex authoring application built on top of it.

Supported formats

• PAA
  • reading
  • processing with Pillow
  • DXT1
  • DXT5
  • ARGB8888
  • ARGB4444
  • ARGB1555
  • AI88
• RTM (plain)
  • reading
  • writing
• RTM (binarized)
  • reading
  • conversion to plain

Note

The modules coming with this package were originally developed as part of the Arma 3 Object Builder plugin for Blender. They are released in this standalone package to facilitate independent use, and easier maintenance.

Requirements

To use the ArmaIO package, Python 3.11 or higher is required.

For some operations, the package depends on NumPy. Some of the extra features might require further dependencies. These are indicated in their respective documentations.

Installation

The preferred method to install ArmaIO is through PyPI, where both wheel and source distributions are made available.

python -m pip install armaio

If not yet published changes/fixes are needed, that are only available in source, ArmaIO can also be installed locally from source, without any external tools. Once the repository is cloned to a directory, it can be installed with pip.

git clone https://github.com/MrClock8163/ArmaIO.git
cd ArmaIO
python -m pip install .

Example

from armaio.paa import PaaFile
from armaio.paa.pillow import open_paa_image  # extra, requires Pillow

paa = PaaFile.read_file("texture_co.paa")
print(paa.format)

with open_paa_image("texture_co.paa") as img:
    print(img.getpixel((1, 2)))
