texture2ddecoder

A python wrapper for Perfare's Texture2DDecoder

Some changes were made to the original code to make it cross-platform compatible.

1. Installation
2. Example
3. Functions

Installation

pip install texture2ddecoder

or download/clone the git and use

python setup.py install

Example

import texture2ddecoder

# load sample data
data = open("astc_sample", "rb").read()

# decode data
width = 512
height = 512
block_width = block_height = 4

decoded_data= texture2ddecoder.decode_astc(data, width, height, block_width, block_height)

# load raw image data
dec_img = Image.frombytes("RGBA", (width, height), decoded_data, 'raw', ("BGRA"))
