Description:
astcdecomp 1.0.3
ASTC_Decomp
An ASTC decoder for PIL.
The decoder uses richgel999/astc_dec to decompress the ASTC blocks.
Installation
Cython required
PIP
pip install astc_decomp
Manual
python setup.py install
Usage
Arguments
block_width: - Block width, in pixels.
block_height: - Block height, in pixels.
is_srgb: - If isSRGB is true, the spec requires the decoder to scale the LDR 8-bit endpoints to 16-bit before interpolation slightly differently, which will lead to different outputs. So be sure to set it correctly (ideally it should match whatever the encoder did).
(optional arg, default : False)
PIL.Image decoder
from PIL import Image
import astc_decomp
#needs to be imported once in the active code, so that the codec can register itself
astc_data : bytes
block_width : int
block_height : int
is_srgb : bool = False
img = Image.frombytes('RGBA', size, astc_data, 'astc', (block_width, block_height, is_srgb))
raw decoder
from astc_decomp import decompress_astc
# ASTC to RGBA
rgba_data = decompress_astc(astc_data : bytes, width : int, height : int, block_width : int, block_height : int, is_srgb : bool = False)
