Documentation

Overview

Package wuffspng decodes PNG images with Wuffs, Google's memory-safe image decoders, compiled from the vendored single-file C release wuffs-v0.4.c (google/wuffs commit 7f70dda95c77b10c087c0908790837b5e9c15713, licensed Apache-2.0 OR MIT; see LICENSE-APACHE and LICENSE-MIT).

On a MiSTer it decoded real 512x700 cover art 2.8 times faster than image/png, with identical pixels. Builds without cgo report ErrUnavailable so callers fall back to image/png.
