HEIF zoo dua nyob rau hauv txhua txoj kev tshiab cov ntaub ntawv duab tuaj yeem ua tau
Kua txais ib tus qauv tshiab hu ua HEIF (High Efficiency Image Format) hauv xyoo 2017. Nws hu nws cov ntawv siv 'HEIC' thiab, nrog rau iOS no 11, hloov cov ntaub ntawv hu ua JPEG (pronounced Jay Peg) nrog HEIF thiab qhov sib thooj Hli (High Efficiency Image Container).
Ntawm no yog vim li cas nws tseem ceeb: cov hom ntawv khaws cov duab nyob rau hauv zoo dua thaum noj ntau ntau qhov chaw cia.
Dluab ua ntej HEIF
Tsim muaj nyob rau xyoo 1992, hom ntawv JPEG yog qhov zoo tshaj plaws rau nws yog dab tsi, tab sis nws tau tsim nyob rau lub sij hawm thaum cov computers tsis muaj peev xwm ua tau li niaj hnub nim no.
HEIF yog ua raws li kev yees duab zoo nkauj uas tsim los ntawm Motion Picture Experts Group, HVEC (tseem hu ua H.265). Tias yog vim li cas nws muaj peev xwm nqa cov ntaub ntawv ntau heev.
HEIF siv li cas rau koj
Ntawm no yog qhov twg HEIF siv rau lub ntiaj teb tiag: lub koob yees duab hauv iPhone 7 tuaj yeem ntes cov ntawv xov xwm 10-ntsis, tab sis hom JPEG tsuas tuaj yeem ntes xim hauv 8-ntsis. Uas txhais tau hais tias lub taub hau HEIF txhawb txhawb lub koob meej thiab tuaj yeem siv cov duab hauv 16-ntsis. Thiab tau txais qhov no: HEIF duab yog kwv yees li ntawm 50 feem pua me dua cov duab qub tau txais kev cawmdim hauv JPEG hom ntawv. Cov duab thev duab ntawd txhais tau tias koj yuav tsum muaj peev xwm muab ob npaug rau ntau cov dluab ntawm koj lub iPhone lossis lwm yam cuab yeej hauv iOS.
Lwm qhov zoo dua yog tias HEIF tuaj yeem nqa ntau ntau hom ntaub ntawv.
Thaum JPEG tuaj yeem nqa tau cov ntaub ntawv uas muaj ib qho duab, HEIF tuaj yeem nqa ob qho tib si thiab cov duab lawv-nws ua zoo li lub khob. Koj tuaj yeem khaws ntau yam duab, thiab tseem tuaj yeem tso suab, qhov tob ntawm daim teb xov xwm, duab thumbnails thiab lwm yam ntaub ntawv nyob rau hauv.
Yuav Siv Cov Kua Siv Heev Dab Tsi?
Kev siv lub HEIC li lub thauv rau cov duab, cov yeeb yaj duab, thiab cov ntaub ntawv txog cov duab txhais tau hais tias Apple yuav xav txog ua ntau ntau nrog koj cov koob yees duab iOS thiab cov duab.
Kua iPhone 7 tus Portrait Mode yog ib qho piv txwv zoo li cas lub tuam txhab yuav ua hauj lwm nrog qhov no. Portrait Mode captures ntau lub versions ntawm ib cov duab thiab stitches lawv ua ke los tsim ntau portraits zoo dua ntawm ntau dua zoo li JPEG.
Lub peev xwm nqa qhov tob ntawm cov ntaub ntawv teb hauv lub thawv lub thawv duab yuav ua kom Kua siv lub tshuab ua kom siv los ua ib feem ntawm cov kev paub txog kev muaj tiag uas nws ua haujlwm rau.
"Cov kab ntawm cov duab thiab cov yeeb yaj duab yog qhov muag plooj, thiab ntau yam peb ntes yog ob qho tag nrho ntawm cov khoom no," said Apple's VP Software, Sebastien Marineau-Mes ntawm WWDC.
Yuav ua li cas HEIF thiab HEIC Ua Hauj Lwm?
Mac thiab iOS users txhim kho iOS no 11 thiab macOS High Sierra yuav tau tsiv mus rau qhov tshiab duab hom, tab sis tsuas yog cov duab lawv ntes tom qab lawv txawj kho tshiab yuav cia rau hauv hom tshiab no.
Tag nrho koj cov duab qub yuav muab cia rau hauv lawv cov duab uas twb muaj lawm.
Thaum nws tawm los sib qiv dluab, Apple's devices yuav tsuas hloov HEIF cov duab rau hauv JPEGs. Koj yuav tsum tsis txhob pom qhov chaw transcoding no.
Qhov no yog vim tias Apple tau muab HVEC video txheem hauv iPhone thiab iPad kho vim nws xub pib ua cov khoom. iPads, iPhone 8 series thiab iPhone X tau xa tawm thiab txiav txim siab cov duab nyob rau hauv video hom yuav luag tam sim ntawd. Nws yog tib yam thaum tuav lub taub hau HEIC.
Qhov no txhais tau hais tias thaum koj xa email tuaj, xa nws nrog lub iMessage, los yog cia li ua haujlwm rau nws hauv ib qho uas tsis muaj kev pab txhawb nqa HEIF, koj ntaus ntawv yuav ntsiag to hloov mus rau JPEG hauv qhov tseeb thiab txav mus rau HEIC.
Raws li iOS thiab macOS cov neeg siv mus rau hom tshiab koj yuav pom ntau thiab ntau cov duab tuav lub npe .heif extension, uas qhia tau hais tias lawv tau txais kev cawmdim hauv hom ntawv.
