SWF Anatomy The structure of a tag Tag Header Type Length Tag Content When the Flash Player encounters a tag with an unknown type, it skips it Extensible Forward compatible Sunday, 25. April 2010
SWF Anatomy Data types used by SWF A tag’s content is made up of various data types. The exact format for each tag is defined in the SWF spec. Some of the data types are rather obscure: Integers Numbers Bit arrays Others UI8 FIXED UB[nBits] String UI16 FIXED8 SB[nBits] RGB UI24 FLOAT FB[nBits] RGBA UI32 FLOAT16 RECT SI8 DOUBLE MATRIX SI16 SI32 EncodedU32 Sunday, 25.
