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)
