Mayelana HEIC

Amafayela e-HEIC ahlinzeka ngokucindezelwa okungcono kune-JPEG kuyilapho egcina ikhwalithi yesithombe, esetshenziswa amadivayisi e-Apple.

Ukusetshenziswa Okuvamile

  • Izithombe ezithathwe ku-iPhone naku-iPad
  • Isitoreji sezithombe esisebenza kahle endaweni
  • Izithombe Ezibukhoma kanye nokulandelana kwezithombe

HEIC Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele HEIC?

I-HEIC (Isitsha Sesithombe Esisebenza Kakhulu) ifomethi yesithombe esekelwe kuzinga le-HEIF elisetshenziswa yi-Apple.
Yebo, futhi lokho kuyinto eyodwa efanele ukwazi mayelana nefomethi. Ukugcina ngalunye kuphinde kuqhube umbhalo odlulile kusithombe esivele sidlule kulo, ngakho-ke ama-artefacts axhunywe - abonakala njenge-blocking ngaphesheya kombhalo kanye nama-haloes ezimbozweni ezinzima ngemuva kwekhulu elincane leminyaka. Hlela kusuka ku-master engalahleki futhi ukhuphule ku HEIC kabili, ekugcineni, endaweni yokuvula futhi ugcine kabusha ifayela elifanayo. I-HEIC igcina izithombe eziqinile ezicindezelwe yi-HEVC - imindeni efana ne-codec esetshenziswa kwividiyo - futhi ingaphatha izithombe eziningi, i-map yobubanzi kanye nokuhlela okungalimaza kwifayela elilodwa.
Ngaphakathi kuka-80 no-90 nganoma yini umuntu uzoyibheka. Ngaphansi kuka-75 i-artefacts iqala ukubonisa ku-skin, i-sky kanye nanoma iyiphi indawo enkulu ehlanzekile; ngaphesheya kuka-95 i-file ikhula ngokushesha ngenkathi akukho muntu okwaziyo ukubona ushintsho. Isilungiselelo asiyimpahla yesithombe, kuyisinqumo mayelana nale mpahla engaphandle ekhethekile — ngakho khetha lapho ihele lizohamba khona, futhi gcina okuyinhloko ngesikhathi esilandelayo lapho ufuna impendulo ehlukile.
Kufomethi enye ekwaziyo ukubukeka, yebo — amaphutha ngefremu ngayinye kanye nokubalwa kwe-loop kugcinwa kwifayela futhi kuthunyelwe. Kufomethi ehlala khona ifremu eyodwa kuphela ephila, ngokuvamile i-first. Kuvidiyo i-loop flag ayikwazi ukubuyela lapho, ngoba umdlali ukhetha ukuthi uphinde. Khangela isivinini sokudlala ngemuva lapho i-frame rate ishintsha: i-rate eqinile ingafinyelela kuphela amaphutha aguqukayo nge-frame.
Kuncane njalo ngonyaka, kodwa ibanga liyiqiniso. Usizo lwesofthiwe lwafika ngokushesha; usizo lwehardware luvela kuphela ngezinto ezintsha, futhi ifoni, i-TV noma umdlali phambi kwakho ungase uqale ngokulula. lapho kuxhaswa khona kungcono kakhulu kunalokho okuhlobene nefomethi eshintshanayo, ngakho-ke kufanelekile ukushintshana ukuze kuthunyelwe futhi kufanelekile ukushintshana ngaphandle kokusebenza. HEIC igcina isithombe esingu-1/2 sobukhulu be-JPG elinganayo esezingeni elifanayo elibonakalayo, ngemibala engu-10-bit kanye ne-alpha channel ekhona.
Akuna. Ifomethi yavela Apple futhi yilokho izinhlelo zayo nesoftware kukhiqiza ngokuzenzakalela, kodwa amafayela ngokwawo zivamile futhi ukufunda kahle elsewhere ngethuluzi elifanele. Ukushintsha lapha kwenzeka kuseva, ngakho akukho QuickTime ukufakela, akukho Apple hardware futhi akukho platform-specific codec pack ihlobene nanoma kuphi kwinqubo.
Ngenxa yokuthi iziphequluli zisebenzisa uhlu oluncane lwefomethi yesithombe futhi HEIC ingaphandle kwayo — ihlobene nokuhlola, uphrinta noma ukuguqula umfutho womsebenzi ngaphezu kwe-web. Ihele alilahleki; lingenakho umbhalo oguqula ikhasi. Ukushintsha ifomethi yesithombe se-web-native kuyisinqumo esincane futhi ngokuvamile kwenza ihele lincane kakhulu. HEIC ifakwe ipatenthi futhi ihlala ivunyelwe: amabhuleki angeke abonisane nayo, amawindows adinga ikhodekhi engeziwe, futhi amafomu aphezulu ambalwa avumelani nesizinda esibanzi.
Kunzima kakhulu, futhi kufanelekile ukuqonda ukuthi kungani: isithonjana siyisihloko, ngenkathi ama-bytes ngaphakathi kufakwe ngefomethi eyodwa ekhethekile. Ukushintsha igama kwenza ihele igama lakhe lithembisa okuthile okuqukethwe kwayo akusho ukunikela, futhi noma yini evula ihele noma liyiphoqa noma liyifunda kabi. Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda uphinde
Kuncane nje. Ama-pixels athathwe yimingwane yonke ekhona: ukukhululwa noma ku-interpolates, okugcoba ama-edge, noma kusetshenziswa i-AI upscaler, okuthuthukisa imingwane efanelekayo engazange ibe ku-original. Okubini kulungile ngenyathelo ephakeme yesibili noma njalo futhi akukho okuguqula ithumbnail ibe yi-poster. Qala kusuka ku-copy enkulu onayo futhi ushintshe ubukhulu ngezansi lapho ukhetho lukhona.
Isuswa ngokuzenzakalela. Ukufaka kanye nemiphumela eguqulwe ihlala kumaseva ethu cishe amahora angama-24, oshiya isikhathi sokulanda imiphumela, bese isuswa ngokuzenzakalela. Ukudluliswa kuhamba nge-HTTPS emigwaqweni emibini. Akukho muntu ofunda okuqukethwe, akukho okuhlobene, futhi akukho okudluliswa kunoma ubani.
Ngokuvamile amasekondi. Amafayela amancane asebenza ngokushesha, futhi izimo ezithatha isikhathi esingokoqobo ziyizinto ezisebenza umsebenzi ongokoqobo: ukurekhodwa okude okudinga ukuphinde kwenziwe ukukopela ifreyimu ngefreyimu, idokhumende elihlolwe lihamba nge-character recognition, noma iqembu elikhulu kakhulu. lapho ukuguqulwa kuphinde kuhlanganise idatha ekhona ihlala ngokushesha kungakhathaliseki ukuthi ihele likhulu kangakanani, ngoba akukho okuzosuswa.
Layisha phezulu ihele lakho ngokulisusa kwikhasi noma ucofoze ukubheka, khetha ifomethi yesikhishwa, bese uqala ukuguqulwa. Ihele eliguqulwe likulungele ukulayisha uma liqediwe.
