HEIC ku-JPG — Ithuluzi Lamahhala Ku-inthanethi

Kungani uguqule i-HEIC ibe yi-JPG

Kusukela ngo-2017 amadivayisi e-Apple agcine izithombe ku-HEIC, ifomethi egcina ikhwalithi ephezulu kufayela elincane kodwa engavulwa izinhlelo eziningi ze-Windows, abahleli bezithombe abadala, amafomu ewebhu, namathuluzi okuthumela imilayezo. Ukuguqulela ku-JPG kukhiqiza ifayela elivuleka yonke indawo, kusukela ku-imeyili nesoftware yamadokhumenti kuya cishe kuyo yonke indawo yokulayisha iwebhusayithi. I-HEIC kuya ku-JPG ihlaziya okwangempela ngenjini ye-heic-to egcinwa ngokusebenzayo bese iyiphinda iyifake njenge-JPG, ukuze ukwazi ukwabelana noma ukulayisha isithombe ngaphandle kwamaphutha okuhambisana.

Isebenza kanjani inqubo yokuguqula

Leli thuluzi lifunda ifayela lakho le-HEIC bese liliguqula lisebenzisa i-WebAssembly esebenza ngaphakathi kwesiphequluli. Isithombe esiguquliwe sidonswa ku-canvas bese sithunyelwa njenge-JPG ngekhwalithi oyikhethayo phakathi kuka-60 no-100 amaphesenti. Ngoba i-decoder yakhiwe nge-WebAssembly yesimanje kunokuba kube ikhodi endala eyayincike ekuhlolweni kwezintambo, isebenza ngaphansi kwe-Content Security Policy eqinile ngaphandle kokunciphisa ukuphepha kwesayithi. Isithombe ngasinye sicutshungulwa kumemori bese sinikezwa ngqo kuwe njengokulanda.

Ikhwalithi nosayizi wefayela

I-JPG yifomethi elahlekelayo, ngakho-ke isilayida sekhwalithi silawula ibhalansi phakathi kokucaca nosayizi wefayela. Ukusetha okungaba ngu-90 amaphesenti kugcina isithombe sibukeka sifana ncamashi ne-HEIC yokuqala ngenkathi kukhiqizwa ifayela elilawulekayo, futhi ukusinciphisa siye ku-60 amaphesenti kwenza ifayela libe lincane kakhulu ukuze lisetshenziswe nge-imeyili noma kuwebhu. Amafayela e-HEIC avame ukuba uhhafu wosayizi we-JPG akhiqizayo, ngoba i-HEIC icindezela ngokuphumelelayo, ngakho-ke lindela ukuthi i-JPG eguquliwe ibe nkulu kancane kunomthombo.

Ubumfihlo nokuphepha

Izithombe zakho azilokothi zishiye idivayisi yakho. Ifayela le-HEIC liguqulwa futhi liphinde liguqulwe endaweni esipheqululini, ngaphandle kokulayishwa, ukugcinwa, noma ukwabelana. Le ndlela yasendaweni kuphela ibalulekile ezithombeni zomuntu siqu, ngoba ungaguqula izithombe zomndeni, izithombe-skrini, noma izithombe eziyimfihlo ngaphandle kokuzinikeza iseva yomuntu wesithathu. Uma uvala ikhasi amafayela asuswa kumemori ngokuzenzakalelayo.

Ukusekelwa kwesiphequluli nedivayisi

I-HEIC to JPG isebenza ezinhlotsheni zamanje ze-Chrome, Firefox, Safari, ne-Edge ku-Windows, macOS, Linux, Android, ne-iOS. Ayikho uhlelo lokusebenza noma isandiso esidingekayo. Ungaguqula izithombe eziningana ngesikhathi esisodwa, futhi isakhiwo esiphendulayo sigcina isilayida sekhwalithi nenkinobho yokulanda kufinyeleleka esikrinini esingu-375 pixel. Ukuguqula isithombe esisodwa se-iPhone esingu-12 megapixel kuvame ukuqeda emizuzwini embalwa.

Mayelana nefomethi ye-HEIC

I-HEIC, okuyisifinyezo se-High Efficiency Image Container, iyifomethi yesithombe esinganyakazi ye-HEIF standard futhi ibilokhu iyimfomethi ezenzakalelayo kuma-iPhones nama-iPads selokhu kwafika i-iOS 11 ngo-2017. Isebenzisa uhlobo olufanayo lokucindezela olusebenzayo njengamavidiyo esimanje, okuyivumela ukuthi igcine isithombe ngekhwalithi ephezulu cishe engxenyeni yesikhala se-JPG efanayo, futhi ingaphinda ibambe izinto ezengeziwe njengamamephu okujula nama-bursts. Ububi ukufinyelela: I-Windows idinga isengezo ukuze ibuke i-HEIC, futhi amawebhusayithi amaningi, abahleli, nezinhlelo zokusebenza zengxoxo zimane ziyenqabe. Ukuguqulela ku-JPG kususa lokho kunzima ngenkathi kugcinwa isithombe esibalulekile.

Amathiphu okwabelana ngezithombe ezigquliwe

Gcina isilayida sekhwalithi eduze kuka-90 amaphesenti lapho isithombe sizophrintwa noma sibukwe eduze, bese usinciphisa siye ku-70 amaphesenti lapho udinga kuphela ifayela elincane ukuze wabelane ngokushesha noma ifomu lewebhu. Guqula ngamaqoqo lapho une-albhamu yonke, njengoba leli thuluzi licubungula ifayela ngalinye ngokulandelana bese liwalanda njengama-JPG ajwayelekile. Khumbula ukuthi ukuguqula kususa izinto ezengeziwe ze-HEIC njengedatha yokujula, kushiye isithombe esiyisicaba, okuyilokho amawebhusayithi amaningi nabamukeli abakulindele. Gcina ama-HEIC akho okuqala kudivayisi yakho uma ufuna ukugcina amafayela amancane nanoma yiziphi izici ze-Apple kuphela.

Indlela Yokusebenzisa HEIC ku-JPG

1. Vula isiguquli se-HEIC to JPG esipheqululini sakho.
2. Engeza isithombe esisodwa noma ngaphezulu se-HEIC noma i-HEIF kusuka kudivayisi yakho.
3. Setha isilayida sekhwalithi ye-JPG phakathi kuka-60 no-100 amaphesenti.
4. Linda ngenkathi isithombe ngasinye siguqulwa futhi siphinde siguqulwe endaweni.
5. Landa izithombe ze-JPG ezigquliwe.
