ispc_texcomp_py
Python bindings for ISPCTextureCompressor.
Installation
pip install ispc_texcomp
Building
ispc has to be available in the PATH for setup.py to work.
Usage
from PIL import Image
import ispc_texcomp_py
# get the rgba data (of an image you want to compress)
img = Image.open(fp)
rgba = Image.tobytes("raw", "RGBA")
# create a RGBASurface
stride = img.width * 4
surface = ispc_texcomp_py.RGBASurface(rgba, img.width, img.height, stride)
# compress the surface (no profile)
# BC1
bc1_compressed: bytes = ispc_texcomp_py.CompressBlocksBC1(surface)
# BC3
bc3_compressed: bytes = ispc_texcomp_py.CompressBlocksBC3(surface)
# BC3
bc4_compressed: bytes = ispc_texcomp_py.CompressBlocksBC4(surface)
# BC5
bc5_compressed: bytes = ispc_texcomp_py.CompressBLocksBC5(surface)
# compress the surface (with profile)
# BC6h
# profile options:
# veryfast, fast, basic, slow, veryslow
profile = ispc_texcomp_py.BC6HEncSettings.from_profile("fast")
bc6h_compressed: bytes = ispc_texcomp_py.CompressBlocksBC6H(surface, profile)
# BC7
# profile options:
# ultrafast, veryfast, fast, basic, slow,
# alpha_ultrafast, alpha_veryfast, alpha_fast, alpha_basic, alpha_slow
profile = ispc_texcomp_py.BC7EncSettings.from_profile("fast")
bc7_compressed: bytes = ispc_texcomp_py.CompressBlocksBC7(surface, profile)
# ETC1
# profile options:
# slow
profile = ispc_texcomp_py.ETCEncSettings.from_profile("slow")
etc1_compressed: bytes = ispc_texcomp_py.CompressBlocksETC1(surface, profile)
# ASTC
# profile options:
# fast, alpha_fast, alpha_slow
profile = ispc_texcomp_py.ASTCEncSettings.from_profile("fas", 8, 8)
astc_compressed: bytes = ispc_texcomp_py.CompressBlocksASTC(surface, profile)
