Blend2D's Blazing-Fast PNG Codec: Outperforming C/C++
2025-03-26
Blend2D library introduces a new high-performance PNG codec that significantly outpaces other C/C++ implementations. Optimized for the DEFLATE algorithm's inherent limitations, this decoder achieves speed improvements through fast decode table construction, optimized decoding loops, and clever use of literal pair techniques. Benchmarks demonstrate superior performance in PNG image decoding, even surpassing the speed of some QOI decoders in certain cases. The project is fully open-source and welcomes contributions.
