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 success = 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.
bazel test //...
Install CMake, and the run:
mkdir build && cd build && cmake .. && make
