HEIF iri nani pane imwe neimwe nzira itsva yefaira mafaira
Apple yakagamuchira mamiriro matsva emufananidzo wakaitwa HEIF (High Efficiency Image Format) muna 2017. Inodana kushandiswa kwayo kwefaira yefaira 'HEIC' uye, ne iOS 11, yakatsiva fomu yefaira inonzi JPEG (inonzi Jay-Peg) ne HEIF uye iyo inowirirana HEIC (High Efficiency Image Container).
Heino chikonzero nei zvakakosha: iyo mafaira anochengetedza mifananidzo muhutano hwakanaka apo achitora nzvimbo shoma yekuchengetedza nzvimbo.
Mifananidzo Kusati kwa HEIF
Yakagadzirwa muna 1992, maitiro eJPEG aive kubudirira kukuru pane zvaive, asi yakavakwa panguva apo makombiyuta akanga asiri ezvo sezvaanoita nhasi.
HEIF inotarisana nepamusoro pepikicha yekunyorwa kwekambaniki yakagadzirwa neMotion Picture Experts Group, HVEC (inozivikanwawo seH.265). Ndosaka iyo inokwanisa kutakura mashoko akawanda.
Maitiro E HEIF Anoshanda Kwauri
Pano ndipo HEIF inoshanda kune wenyika chaiyo: kamera mu iPhone 7 inogona kutora 10-bit ruvara rwemuvara, asi fomu yeJPEG inogona kungotora ruvara mu 8-bit. Icho chinoreva kuti HEIF format inobatsira kujekesa uye inokwanisa kubata mifananidzo mu 16-bit. Uye tora izvi: chifananidzo che HEIF chave nechepamusoro makumi mashanu kubva muzana kubva muzana kubva mufananidzo wakafanana wakachengetwa muJPEG format. Chifananidzo ichocho chinomiririra chinoreva iwe unokwanisa kukwanisa kuchengeta mifananidzo miviri yakawanda pane iPhone yako kana imwe iOS device.
Imwe nzira yakakura ndeyokuti HEIF inogona kutakura mhando dzakawanda dzemhando dzakasiyana dzemashoko.
Kunyange zvazvo JPEG inogona kutakura data ine chinyorwa chimwe chete, HEIF inogona kutakura mifananidzo miviri isina kutevedzana uye kuenzaniswa kwayo-inoita sechitakiti. Iwe unogona kuchengetedza mifananidzo yakawanda, uye unogonawo kuisa mutinhi, kudzika kwemashoko emunda, zvifananidzo zvidhori uye mamwe mashoko arimo.
Ko Apple ingashandisa sei HEIC?
Uku kushandiswa kwe HEIC sechitinha chemifananidzo, mavhidhiyo, uye ruzivo rwakabatana nemufananidzo zvinoreva Apple anogona kufunga nezvekuita zvakawanda nezvamera enyu iOS nemifananidzo.
Apple's iPhone 7's Portrait Mode muenzaniso wakanaka wekambani inogona kushanda neizvi. Mifananidzo inotora zvinyorwa zvakawanda zvechifananidzo uye inozvibatanidza pamwe chete kuti zvigadzire zvifananidzo zvakanakisisa pane unhu hwakakwirira kupfuura JPEG.
Iko unyanzvi hwokutakura zvakadzama zvemashoko emumunda mukati mezvigadziro zvemufananidzo we HEIC zvinogona kuita kuti Apple ishandise iyo yakanyanyisa maitiro sechikamu chezvinhu zvechokwadi zvekutengesa zvairi kushanda.
"Mutsetse pakati pezvifananidzo nemavhidhiyo zvakajeka, uye zvakawanda zvatinotora ndezvekubatanidzwa kwezvinhu zviviri izvi," akadaro Apple's VP Software, Sebastien Marineau-Mes paWWDC.
HEIF na HEIC Vanoshanda sei?
Mac uye vashandi veIOS vanoisa iOS 11 uye macOS High Sierra vachangoendeswa kunzvimbo itsva yemufananidzo, asi chete mifananidzo yavanotora mushure mekuvandudza kwayo ichachengetwa mumutauro uyu mutsva.
Mifananidzo yako yose yekare ichachengetwa mumutauro wavo wakanga uripo.
Kana zvasvika pakugovana zvifananidzo, madivaysi eApple achangoshandura HEIF mifananidzo kuva JPEGs. Iwe haufaniri kuona kuti kudarika uku kunoitika.
Izvi ndezvokuti Apple yakapa HVEC video yepamusoro mukati memhare ye iPhone ne iPad sezvo yakatanga kubudisa iyo michina. iPads, the iPhone 8 series uye iPhone X inogona kukodhirira uye kugadzirisa mifananidzo mumavhidhiyo mapurogiramu anenge pakarepo. Izvo zvakafanana kana uchibata HEIC.
Izvi zvinoreva kuti kana iwe unyoresa mifananidzo, tumira nayo iMessage, kana kuti ingoshanda pairi mune imwe purogiramu isina hutsigiro hwe HEIF, chigadziro chako chichishandura chinyararire kuJPEG munguva chaiyo uye chichiendesa ku HEIC.
Sezvo iOS nevashandi veMACOS vachienda kune imwe itsva maitiro muchaona mifananidzo yakawanda inotakura .heif filename extension, iyo inomiririra kuti inoponeswa mumutauro.
