That file contains // the entire Wuffs standard library, implementing a variety of codecs and file // formats. Without this macro definition, an optimizing compiler or linker may // very well discard Wuffs code for unused codecs, but listing the Wuffs // modules we use makes that process explicit. Preprocessing means that such // code simply isn't compiled. // // For Skia, we're only interested in particular image codes (e.g. GIF) and // their dependencies (e.g. BASE, LZW). #define WUFFS_CONFIG__MODULES #define WUFFS_CONFIG__MODULE__BASE #define WUFFS_CONFIG__MODULE__GIF #define WUFFS_CONFIG__MODULE__LZW #include "wuffs-v0.2.h"
