pyTGA
A pure Python module to manage TGA images. This module is compatible with Python 2 and Python 3 and we refer on the New TGA Format.
The library supports these kind of formats (compressed with RLE or uncompressed):
- Grayscale - 8 bit depth
- RGB - 16 bit depth
- RGB - 24 bit depth
- RGBA - 32 bit depth
As you can see in the example you can use the python basic types for data.
Install
Simply type:
python setup.py install
Test
cd test
python test_module.py

Example
import pyTGA

data_bw = [
[0, 255, 0, 0],
[0, 0, 255, 0],
[255, 255, 255, 0]
]
data_rgb = [
[(0, 0, 0), (255, 0, 0), (0, 0, 0), (0, 0, 0)],
[(0, 0, 0), (0, 0, 0), (255, 0, 0), (0, 0, 0)],
[(255, 0, 0), (255, 0, 0), (255, 0, 0), (0, 0, 0)]
]
data_rgba = [
[(0, 0, 0, 0), (255, 0, 0, 150), (0, 0, 0, 0), (0, 0, 0, 0)],
[(0, 0, 0, 0), (0, 0, 0, 0), (255, 0, 0, 150), (0, 0, 0, 0)],
[(255, 0, 0, 150), (255, 0, 0, 150), (255, 0, 0, 150), (0, 0, 0, 0)]
]
