I-HEIF ibhetele ngandlela-thile indlela ifomati entsha yefayile ifumaneka ngayo
I-Apple yamkela ifomati yomfanekiso omtsha obizwa ngokuba yi-HEIF (ifomati yeSithombe esiPhezulu soPhumelelo) ngo-2017. Ibiza ukusetyenziswa kwayo kwifom yefayile 'HEIC' kwaye, nge-iOS 11, ithathe indawo yefayile yefayile ebizwa ngokuba yiJPEG (ebizwa ngokuba nguJay-Peg) kunye ne HEIF kunye i-HEIC ehambelanayo (i-High Efficiency Image Container).
Nantsi kutheni kubalulekile: ifomathi igcina imifanekiso kwimigangatho engcono ngelixa ithatha indawo encinane yokugcina.
Imifanekiso phambi kwe-HEIF
Uphuhliswe ngo-1992, ifomathi ye-JPEG yayiyimpumelelo enkulu kwinto ebeyiyo, kodwa yakhiwe ngexesha apho iikhomputha zangezona zikwazi njengokuba zikhona namhlanje.
I-HEIF isekelwe kwi-teknoloji yoxinzelelo yevidiyo ephakamileyo eyenziwe yiQela leNzululwazi yeeMifanekiso, i-HVEC (eyaziwayo njengeH.265). Yingakho ikwazi ukuthwala ulwazi oluninzi.
I-HEIF Isebenza Kanjani Kuwe
Nantsi apho i-HEIF isebenzayo kwilizwe langempela: ikhamera kwi-iPhone 7 ingabamba ulwazi lombala we-10-bit, kodwa ifomathi ye-JPEG ingabamba umbala kwi-8-bit. Oko kuthetha ukuba ifomathi ye-HEIF isekela ukukhanya kwaye iyakwazi ukuphatha imifanekiso kwi-16-bit. Uze ufumane oku: umfanekiso we-HEIF ungaphantsi kwama-50 ekhulwini kunomfanekiso ofanayo ogcinwe kwifomethi yeJPEG. Ukuxinwa komfanekiso kuthetha ukuba kufuneka ukwazi ukugcina imifanekiso emibini kwi-iPhone yakho okanye kwenye iOS device.
Enye inzuzo enkulu kukuba i-HEIF inokuthabatha iintlobo ezininzi zeenkcukacha.
Ngelixa i-JPEG inokuthwala i-data equkethe umfanekiso omnye, i-HEIF inokuthatha imifanekiso emibili kunye nokulandelelana kwayo-ifana nekhonkco. Ungagcina imifanekiso emininzi, kwaye unokubeka i-audio, ubunzulu beenkcukacha zentsimi, izithonjana zezithombe kunye nolunye ulwazi apha.
I-Apple ingayisebenzisa njani i-HEIC?
Ukusetyenziswa kwe-HEIC njengekhonkco kwimifanekiso, iividiyo, kunye nolwazi olunxulumene nomfanekiso lithetha ukuba i-Apple ingacinga ngokukwenza okungakumbi ngeekhamera ze-iOS kunye nemifanekiso.
Imoji ye-iPhone ye-iPhone ye-iPhone 7 ngumzekelo omhle wendlela inkampani inokusebenza ngayo nale nto. Imoji yePortrait ithatha iinguqu ezininzi zeesithombe kwaye zibafaka ndawonye ukuze zenze iifayile ezingcono kakhulu kumgangatho ophezulu kakhulu kuneJPEG.
Umthamo wokuphatha ubunzulu beenkcukacha ngaphakathi kwintsimbi ye-HEIC inokwenza ukuba i-Apple isebenzise ifomati egxininisiweyo njengenxalenye yobuchwepheshe obunyanisekileyo obuthathakayo.
"Umgca phakathi kweefoto kunye namavidiyo kuphazamiseka, kwaye ezininzi izinto esizibambayo zidibanisa zombini ezo zinto," kusho i-Apple VP Software, iSebastien Marineau-Mes kwiWWDC.
I-HEIF kunye ne-HEIC Work?
Abasebenzisi beMac kunye ne-iOS ukufaka iOS 11 kunye ne-MacOS High Sierra baya kutshintshwa ngokuzenzekelayo kwifomati entsha yomfanekiso, kodwa kuphela imifanekiso abayibamba emva kokuba iphuculwe iya kugcinwa kule fom entsha.
Yonke imifanekiso yakho endala iya kugcinwa kwifomati yazo yeseleko.
Xa kuziwa kokubelana ngemifanekiso, iifayile ze-Apple ziza guqula i-HEIF imifanekiso ibe yi-JPEG. Akufanele uqaphele oku kuqhutywayo.
Oku kungenxa yokuba i-Apple inikezele ngevidiyo ye-HVEC ngaphakathi kwe-iPhone kunye ne-iPad yehadi ye-hardware ekubeni iqala ukuvelisa ezo mveliso. iPads, i- iPhone 8 series kunye ne- iPhone X ingadibanisa kwaye ihlaziye imifanekiso kwifom yevidiyo ngokukhawuleza. Kuyafana nokuphatha i-HEIC.
Oku kuthetha ukuba xa uthumela i-imeyile umfanekiso, thumela nge iMessage, okanye usebenze nje kuyo kwiprogram engenayo inkxaso ye-HEIF, ifowuni yakho iya kuyiguqula ngokucokisekileyo ibe yi-JPEG ngexesha langempela kwaye uyisithumele kwi-HEIC.
Njengoko iOS kunye nabasebenzisi beMACOS befudukela kwifomathi entsha, uya kubona imifanekiso eninzi eneenkcukacha ezithwala i-heif yegama lefayile, elithetha ukuba ligcinwa kwifomathi.
