etcpack (for python)
A cython wrapper for etcpack that integrates etcpack into Pillow as codec.
Install via
python setup.py install
- Cython is required
usage example
from PIL import Image
import etcpack
#needs to be imported once in the active code, so that the codec can register itself
raw_etc_image_data : bytes
mode = 'RGB'/'RGBA' # depending on the ETC mode
args = (x, ) # x depending on the ETC mode
img = Image.frombytes(mode, size, raw_etc_image_data, 'etc2', args)codec table
| ETC mode | arg | mode |
|---|---|---|
| ETC1_RGB_NO_MIPMAPS | 0 | RGB |
| ETC2PACKAGE_RGB_NO_MIPMAPS | 1 | RGB |
| ETC2PACKAGE_RGBA_NO_MIPMAPS_OLD | 2 | RGBA |
| ETC2PACKAGE_RGBA_NO_MIPMAPS | 3 | RGBA |
| ETC2PACKAGE_RGBA1_NO_MIPMAPS | 4 | RGBA |
| ETC2PACKAGE_R_NO_MIPMAPS | 5 | R or A |
| ETC2PACKAGE_RG_NO_MIPMAPS | 6 | RGA |
| ETC2PACKAGE_R_SIGNED_NO_MIPMAPS | 7 | R or A |
| ETC2PACKAGE_RG_SIGNED_NO_MIPMAPS | 8 | RGA |
| ETC2PACKAGE_sRGB_NO_MIPMAPS | 9 | RGB |
| ETC2PACKAGE_sRGBA_NO_MIPMAPS | 10 | RGBA |
| ETC2PACKAGE_sRGBA1_NO_MIPMAPS | 11 | RGBA |
notes
- compression isn't implemented
- RG is untested
