| # astc-codec |
| |
| 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); |
| ``` |
| |
