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.
Simply type:
python setup.py installcd test
python test_module.pyContributions are welcome, so please feel free to fix bugs, improve things, provide documentation. For anything submit a personal message or fork the project to make a pull request and so on... thanks!
