The code for where swftools writes this out is in src/swfc.c. It occurs in
one function, s_addcharacter (included below), which gets called for a
variety of types - boxes, images, audio files, etc. Its use in export
seems to be at odds with the above documentation which indicates that it is
obsoleted by PlaceObject2, the purpose of which is to place characters on
the stage.
Since swfc is actually outputting this flag, not just recognizing it in
existing SWFs, I had hoped someone on this list (perhaps the author?) could
offer insight as to its purpose in swfc output.
from swfc.c:
static void s_addcharacter(const char*name, U16 id, TAG*ctag, SRECT r)
{
if(dict_lookup(&characters, name))
syntaxerror("character %s defined twice", name);
character_t* c = character_new();
c->definingTag = ctag;
c->id = id;
c->size = r;
dict_put(&characters, name, c);
if(do_exports) {
tag = swf_InsertTag(tag, ST_NAMECHARACTER);
swf_SetU16(tag, id);
swf_SetString(tag, name);
tag = swf_InsertTag(tag, ST_EXPORTASSETS);
swf_SetU16(tag, 1);
swf_SetU16(tag, id);
swf_SetString(tag, name);
}
}
