astc-codec is a software ASTC decoder implementation, which supports the ASTC LDR profile.

Example usage:

#include <astc-codec/astc-codec.h>

// ...

std::vector<uint8_t> astc = LoadMyASTCData();
const size_t width = 640;
const size_t height = 480;

std::vector<uint8_t> result;
result.resize(width * height * 4);

bool result = astc_codec::ASTCDecompressToRGBA(
    astc.data(), astc.size(), width, height, astc_codec::FootprintType::k4x4,
    result.data(), result.size(), /* stride */ width * 4);


Install Bazel, and then run:

bazel build :astc_codec -c opt

astc-codec has been tested on Mac and Linux.

Run Tests

bazel test //...
