Ku-GIF okanye kungabi yi-GIF?
Iifayile ze-GIF zisetyenziswa kakhulu kwi-intanethi, kunye nezinye iifom zefayile ezinjengeJPGs kunye ne-PNG. I-GIF isingqamaniso seFayili yokuTshintshana kweeDiskrikhi esebenzisa indlela yokunciphisa idatha yedatha eyanciphisa ubukhulu befayili ngaphandle kokulahleka kwexabiso. I-GIF ingaqukatha imibala engama-256 ukusuka kwi-24-bit ye- RGB yesikhala sombala, leyo-nangona loo nto ingava ngathi imibala eninzi-impela ipalali elinganiselwe eyenza i-GIF iluncedo kwezinye iimeko kodwa ezingalunganga kwabanye.
I-GIF yaqale yaqulunqwa yiCompuServe ngo-1987 ukuya kwaye iyasetyenziswa ngokubanzi kwi-intanethi ngenxa yokuphatheka kwayo kunye nobukhulu obuncinci, ukwenza i-GIF ifumaneke kuyo nayiphi na isiphequluli nakweyiphi na indawo, kwaye ikhawuleze ukulayisha.
Xa ifomethi yeGIF isebenza kakuhle
I-GIF, echongwe nge-.gif isandiso sefayili, ngokuqhelekileyo iyona khetho ekhethekileyo kwimifanekiso enombala oqinileyo, obhaliweyo kunye nemilo elula. Imizekelo iza kuba amaqhosha, imifanekiso okanye amabhanki, umzekelo, ekubeni banemizila enzima kunye nemibala elula. Ukuba usebenza neefoto okanye ezinye iimpawu ezibonisa ukukhishwa kombala, i-GIF ayilona nto ibhetri yakho engcono kakhulu (cinga i-JPG endaweni yoko, nangona i-JPG ingabonakali ukuxinzelelwa kokulahlekelwa yi-GIF).
Ngokungafani neefayile zeJPG, iifayile ze- GIF zixhasa imvelaphi ebonakalayo . Oku kuvumela iifayile ze-GIF ukudibanisa nemibala yangasese yewebhu. Nangona kunjalo, ekubeni iipekseli zinokuba yi-100% ecacileyo okanye i-100% opaque, awukwazi ukuyisebenzisa ngokucacileyo, ubeke izithunzi kunye nemiphumo efanayo. Ukufezekisa loo fayile, i-PNG ifanelekileyo.
Enyanisweni, i-PNG, imele i-Portable Network Graphics, ithathe ukugqithiswa kwe-GIF njengendlela ehamba phambili yefayile yefayile. Inika uxinzelelo olungcono kunye nemisebenzi eyongezelelweyo, kodwa ayixhasayo iifayile, eziphi iifayile ezisetyenziswa ngokuqhelekileyo.
GIF ezinomxholo
Iifayile ze-GIF zingaqukatha izilwanyana , ukudala iifayile ezibizwa ngokuba yi-GIF eziphathekayo. Ezi zidlalwa kwiwebhsayithi, nangona zingasetyenziswa ngokubanzi njengoko zaziqhelekile. Uyakhumbula imihla ye-animated "ekwakheni" imifanekiso? Lezo zaziyi-GIF eziphambili ze-animated.
Kodwa kusekho ukusetyenziswa okuqhelekileyo kwezi ziboniso. Zingasetyenziselwa kwizikhangiso, ukuthengisa i-imeyile okanye i-demos elula ye-diy-naphi apho umfanekiso wesimo nje awuyi kuyenza inkohliso.
Awudingi iprogram yemveliso ebiza kakhulu ukudala i-GIF ephathekayo. Enyanisweni, unokwenza ngokukhululeka usebenzisa enye yezixhobo ezininzi ze-intanethi, ezifana ne-GIFMaker.me, makeagif.com okanye i-GIPHY.
Abanye abasebenzisi bewebhu bavaliwe ngopopasho olukhulu, nangona kunjalo, ke sebenzisa le fomathi ngokucophelela kwaye ngokukhawuleza, kwaye apho kuya kuba nefuthe elikhulu.
Indlela yokubiza i-GIF
Uninzi lwabaqulunqi balichaza i-GIF ngolukhuni "g" njengelo gama elithi "unike." Okuthakazelisayo, nangona kunjalo, umqhubi walo uSteve Wilhite weCompuServe wayefuna ukuba kuthethwe nge-soft "g" njenge "jif" njengeJif yebhanan. Izwi elidumileyo phakathi kwabaphuhlisi beCompuServe kuma-80s "Abathuthukisi be-Choosy bakhetha i-GIF" njengomdlalo kwi-adan yebhanti ye-peanut yelo xesha.
