[ FRAME ] <pocet_chunku 1b><delka frame 3b>
[CHUNK] <cislo_akce 1b><delka_chunku 3b> !pozor delka je 3 bajtova (tj 16MB)
0 - PRADNY CHUNK
1 - LZW FULL SCREEN
2 - MGIF DELTA
3 - HICOLOR PALETE
4 - SOUND TRACK
5 - TEXT TRACK
6 - MGIF COPY
7 - SOUND INIT
Popis Chunku:
PRAZDNY_CHUNK - muze obsahovat soukrome informace
LZW_FULL_SCREEN
- ihned za hlavickou nasleduje LZW komprimovany obrazek
v rozliseni 320x180 256 barev
MGIF_DELTA
- cely blok je LZW komprimovany. Po dekomprimace blok obsahuje
dva druhy informaci. Prvni DWORD je ofset od pocatku dat
ktery ukazuje na zacatek graficke informace. Po tomto
DWORDU jsou ulozeny data o umisteni grafickych bodu v obrazu
Prvni byte znaci, kolik je nutne preskocit slov. (tj *2 byte)
Dalsi byte znaci, kolik je nutne zapsat slov (tj *2 byte)
Po tomto bytu je nutne prenest presne tolik slov z
grafickeho bloku na obrazovku. Dvojice bajtu se opakuji
dokud ani jeden z nich nema nejvyssi 2 bity nastavene.
Pak tento byte znaci ze uz na radce nic vic neni. Dolni cast
byte (tj 6 bitu) pak udava pocet radku, ktere je treba pre-
skocit. (nula=zadny).
HICOLOR PALETTE
- Prvni byte znamena pocet aktivnich barev. Pak nasleduje
paleta ve formatu xRRRRRGGGGGBBBBB. Rozdil oproti vsem
beznym paletam je v tom ze neni treba v palete udrzovat
barvy, ktere uz na obrazovce jsou, protoze zmena palety
se neprojevi na jiz zobrazenem obrazku.
SOUND_TRACK
- Kazdy frame obsahuje zvukovou stopu. Je to RAW format.
Pro verzi MGIF97 zde je zvukova informace ulozena ve
zvukove kvalite 16-bit stereo 22000Khz, ovsem komprimovana
na 50% jako MUS.
TEXT_TRACK
- Navic je ve mozne ve frame umistit textovou zpravu (titulek)
Prvni WORD udava dobu zobrazeni (pocet frame).
Pote nasleduje text zakoncen znakem 0;
MGIF_COPY - Za timto CHUNKEM je ulozen blok dat v nezakomprimovanem
tvaru(tj 57600byte);
