3. Functions

Installation

pip install etcpak

or download/clone the git and use

python setup.py install

Example

from PIL import Image
import etcpak

# load image
img = Image.open(file_path)

# get image data
img_data = img.convert("RGBA").tobytes()

# compress data
compressed = etcpak.compress_to_dxt5(img_data, img.width, img.height)

Functions

• all functions accept only arguments, no keywords
• the given data has to be RGBA for the RGB function as well
