lodepng-turbo is a PNG image codec that uses SIMD instructions (MMX, SSE2, AVX2, NEON) to accelerate baseline PNG decompression on x86, x86-64, ARM systems.
lodepng-turbo is a PNG image codec that uses SIMD instructions (MMX, SSE2, AVX2, NEON) to accelerate baseline PNG decompression on x86, x86-64, ARM systems. On x86 and x86-64 or ARM systems, lodepng-turbo is twice as fast as libpng, but it may be slower elsewhere. With lodepng-turbo, its highly optimized libdeflate and depng prediction routines perform significantly better than lodepng(origin) and libpng.
lodepng-turbo implements both the traditional lodepng API and the less powerful but more direct TurboPNG API.
Build lodepng-turbo with gcc/clang and GNU make.
$ makelodepng is a very easy-to-understand png library, which is the foundation of this library.
libdeflate is a very fast zlib compatible codec, and substantial decode processing is realized with this library.
SimdTests is a public domain to test SIMD optimized functions related mostly to 2D computer graphics.
